We are shutting down for a hard earned break from 18th August and back on 1st September, any online purchases will be dealt with when we get back, if there are any high priority emails we will endeavour to answer during this period.

 We had a fantastic time at: on 18-19-20th July 2008, we would like to thank all at Land Rover Monthly Magazine for letting us exhibit our wares in the LRM marquee, we had great response and a 1000 of our promotional leaflets were given out from our stand. The charity raffle (proceeds and charity will be announced in due course) to win a full kit: KIT001 plus Stainless tank tray DVT021 and low level sensor DVLL2 worth a total of £603.78 was drawn at 14.00 on Sunday and the lucky winner, with ticket number 158 (AU 834926) is Mark Thrower of Colchester who will receive his kit in a couple of days, unfortunately he was not present at the draw so we notified him by phone today, after a little scepticism as we announced he was the lucky winner (how many people have had a phone call and someone asks to check you personal details as you have won a wonderful prize? It makes you a little wary, anyway, once he found out this was a genuine phone call, the mood lightened considerably!), he is over the moon and will be fitting his kit to a 200TDi. We would like to thank everyone else who contributed to the charity raffle and wish you better luck next time.

We also converted this beautiful new Defender 300TDi everything went very smoothly and as usual our Veg Kit Demo Rig was a great attraction.

We are proud to announce our new controller. From now on it will be included in each and every kit we supply and fit, see the range of kits HERE. This builds on the extremely well proven two tank system with over 7000 vehicles already converted (yes that's correct, OVER SEVEN THOUSAND), to make it truly a formidable world beating system.

The new controllers electrical system will allow auto or manual switching to vegetable oil and is easily configurable for looped (short cycle) or return systems (long cycle). The controller also has a new wiring loom, which allows for quicker and simpler installation.

ISO 9001:2000 CERTIFIED

By far the most common 12v 8mm kit and tank combination is KIT001 at £530.97 VAT inclusive, take advantage of our Special Offers and buy KIT001 online to claim a free coolant hose kit, all in all, tremendous value.

heater, (please do not confuse these solenoids with lesser makes, these are top quality, designed for long service, high throughput and installation flexibility and they do not stick. Better than six port motorised valves as they cannot be timed independently), Discreet Dashboard Switch Console (50mm high x 70mm long x 22mm deep) with Vegetable oil green LED, system up to temperature green LED, Diesel-Therm heater operation amber LED, system flushing amber LED and with the additional option of a Low Level tank float switch a red LED to indicate auxiliary tank is low on fuel, for the optional low level float switch DVLL2 see HERE; of course the "still switched to veg" warning sound is still incorporated to remind the driver that they have not yet flushed back to Diesel, relay and plug/socket wiring loom, with Quick Purge timer and additional extra relay bases for optional return and pump installation, Fuel Tubing, Accessory Bag including clips, lugs, ferrules, fuse etc. KIT001 also includes: 22l tank for start-up diesel with additional outside air vent to prevent smells inside vehicle, Tank Straps.

All this for £530.97 VAT inclusive.

Note: 22 Litre tank is intended for start-up diesel, vegetable oil goes into original Diesel tank! This is probably why this kit combination is so popular, because the tank takes up little space, and you utilise the existing tank so there is no loss of range. It is of course possible to use the original tank for start up Diesel but usually this requires a larger auxiliary vegetable oil tank, you can choose which tank suits best HERE. If you wish to provide your own tank and require only a kit, choose from the range HERE.

Dear Sir

I bought a 3 year old Skoda Felicia in August 2000, and DieselVeg converted it to run on vegetable oil.

It has a Lucas pump, so I am careful to use new oil, or well filtered used oil.

It has run now for 3 ^1 /_2 years with no problems.

I've done 65,000 miles since the conversion, it had done 14,000 on diesel before that.

Possibly that's the most for a car with a Lucas pump.

Hi guys.

2nd January 2007- 137,500miles- 5 1/2 times around the world ON RECLAIMED VEG OIL!! and the engine as sweet as it ever was after sticking stringently to the maintenance programme advised by Dieselveg- DO YOU NEED ANY MORE PROOF?? This is the very best of motoring!! I thank God for the day I walked into your workshop! Hey guys, Nick , Clive and Andy, Have a brilliant 2007. May you all be  millionaires and may all your problems be small. 

A VERY GRATEFUL CUSTOMER.

Hi,

Here is the email as requested regarding the rover, I will email pics at a later date if required. I may well pop down from Telford over the next two weeks or so. I have experimented with various routing of pipe work on the rover, to get the best from the kit, ie so you dont use to much diesel to prime the pump etc etc, if you want to know more just drop me a line. You can chop and change the email if you require to suit yourselves.

Around 5 years ago I purchased a Vegetable oil conversion kit from Dieselveg to fit to my Rover 825D (VM engine) 1995, the kit has been super reliable to date (3/10/06) and is capable of being transferred to another type of vehicle if required.

Now the interesting bit... the car has ran extremely well (same performance etc) with no problems on clean 100% veg oil for 100,000! yes 100,000 miles! Saving me lots and lots of money!! And of course being better for the environment. The Rover now has 230,000 miles on the clock.

Around one month ago a core plug sprung a leak (common problem with the Rover 825D) so the cylinder heads had to be removed (unfortunately I didn’t take any photographs) The pistons, bore and cylinder heads ( the rover has 4 separate heads) were all as clean as a whistle with no apparent wear or gumming up, as rumour has it! The injectors were in excellent condition, having done over 130,000 miles in my possession, and I have never had to change them. So why fix something that’s not broken so I put the original injectors back in the vehicle.

The vehicle is now back on the road saving me money for every mile I drive (oh, and of course being better for the environment)

Also please remember that the veg oil kit in my possession is of an older design and having done my home work the newer kits now supplied are more user friendly.

Just for those that maybe interested the early Range Rover 2.5D and Jeep Cherokee 2.5D have the same VM engine which appears to be an ideal candidate for veg oil.

Jason.

Dieselveg Bio-Band

The Bio-Band© Silicon Filter Heater (see right) was especially developed by Dieselveg after numerous calls and requests from haulage companies and private individuals alike regarding Bio-Diesel usage. Bio-Diesel is relatively trouble free in summertime but in cold temperatures gelling up of the fuel at the filter frequently occurs, this causes restriction of fuel flow, resulting in poor starting and running performance.

ATG Gear Pumps

Gear pumps with variable pressure for use as assist / lift pumps and for systems where a higher pressure pump is required e.g. in-tank pumped common rail. Read More

Bioplantrix IDH1224 Electronic Induction Heating for Injection Pipes.

We are getting TRULY ASTOUNDING results using this heater, take a look at the following graphs which were produced during testing the system on our Toyota Surf, we fitted temperature probes and recorded the data, once with the Bioplantrix unit switched on then the following day we did the same journey with the unit switched off. See Graph with unit switched on. Then compare this with Graph with unit switched off. Print these two documents out then you will be able to see them side by side TOTALLY AMAZING we are sure you will agree?

The system was developed to directly heat high pressure injection pipes to increase injecting temperatures. Read More

Why should I convert, isn’t it easier to mix?

We are finding more and more that potential veg oil users are being given misinformation on exactly what they should and should not do to properly achieve their goal, in an effort for you to become responsible users rather than abusers we decided this article must go onto our home page. Like it or lump it, as ever we tell it straight and to the point.

We have been asked so many times “what mix of veg oil would suit my vehicle”, “cant I just throw it in the tank” or “my mate has been running pure veg oil with no problems”, many people state “my mate says”, its funny how many “mates” are experts isn’t it? We have always answered this type of question with a shortened version of the contents below.

First of all let’s get down to the basics of running diesels on veg oil. SVO (straight vegetable oil) is many times thicker than diesel at ambient temperatures, the lower the temperature i.e. in winter, the thicker the SVO, in summer, the thinner it is, but even then it is still many times thicker than Diesel.

The mechanics for successful combustion for SVO is very simple, once it is heated to normal engine temperatures around 80°C + it burns similarly to Diesel.  But it really is no use heating veg oil and squirting it into a cold unmodified engine, the net effect is cold start problems as outlined in the following paragraph. Everything, the engine and the SVO going into that engine must be at a similar hot temperature.

There are many common misconceptions about running diesels on veg oil, just because the vehicle appears to start and run ok with a mix on an unmodified engine, then it must be OK? WRONG. It must be stressed at this stage that the following should be read in conjunction with our section on injection pumps.

Vegetable oil ONLY burns cleanly when hot, so when mixing, most of all potential damage will be caused when starting from cold, when the fuel is forced through injectors, the fuel is thicker thereby putting tremendous unnecessary strain on the fuel system pump and injectors, at least shortening their life, the cold veg oil part of the mix does not fully atomize, you need a fine atomized spray of fuel for clean combustion, larger droplets than intended will form, when they are larger they become incombustible, now large droplets of incombustible fuel have to go somewhere, some will be thrown out of the exhaust causing unnecessary pollution and acrid smell, some accumulates on the internals of the engine running the risk of carbon build up which can stick piston rings into their grooves and can damage surfaces on bores. The remainder will find its way down the bores into the engine oil causing greater engine oil contamination  than normal.

ALL diesel engines have a certain amount of fuel to engine oil contamination to a greater or lesser extent dependant upon many things, pre-combustion chambered engines tend to suffer less than direct injection engines. This is why, on any diesel, when engine oil is changed it immediately appears black again, this is soot / carbon deposits amongst other contaminates. When diesel contaminates engine oil it thins it out then most evaporates, when veg oil contaminates it thickens due to polymerisation and there is no evaporation. When engines are started from cold on SVO or a mix this ingress can be greatly accelerated. If you find that the dipstick level is rising the sump is filling up, it is a sure sign that your engine oil is being contaminated with veg oil, if left unchecked an overfull sump can cause damage. A simple test for polymerisation is to dip then get sample oil between thumb and forefinger, if it is sticky, CHANGE THE OIL, with converted engines in good condition this does not usually happen until normal service mileage is due, if at all. With converted engines we recommend engine oil changes every 5000 to 6000 miles, a good mineral based oil or semi synthetic oil is ok for some engines but a high spec plant based engine oil such as Plantomot 5w40 as offered here is even better as these oils resist polymerization well, conserve energy and are rapidly biodegradable. We advise use of these oils especially on higher powered engines and direct injection types. In extreme cases where the engine has gone way over its service interval and/or engine is not in good repair the engine oil can turn to sludge. BE WARNED.

This all usually happens gradually over time so is not immediately noticeable, it is the false sense of security in which “my mate says” everything is hunky dory. Because there is usually no real noticeable difference except for maybe more smoke out of the exhaust than would be normal but of course “my mate” isn’t bothered is he? He’s at the front driving and the exhaust’s at the back in some other drivers face, of course this is where it really detracts and puts other road users off, and gives us a bad name, because they really do smell strongly of burning cooking oil, or should I say unburned cooking oil, there is a vast difference in the smell of veg oil when it is being burned properly, the faint smell of a barbeque with no more smoke than when running on Diesel is what it should be like.

The above scenario will be lesser or greater in proportion to the amount of veg oil mixed, the ambient temperatures at which it is used and the tolerance to veg oil of the particular engine, generally older pre-combustion type engines will be more forgiving, for instance the older type Mercedes pre-combustion engines are the most tolerant due to their particular unique design than the more modern direct injection engines. With common rail and equivalent PD type engines and those with in-tank lift pumps (some in-tank lift pumps are barely capable of pumping diesel let alone SVO!) and engines with Lucas type distributor injection pumps you can really get into trouble very quickly.

Another problem is that most diesel filters are either inadequately heated or not heated at all causing veg oil to wax up and hinder or stop fuel flow.

Mixing a small amount of veg oil to an unmodified diesel is, however, undoubtedly beneficial. Five percent would probably not hinder combustion and would aid fuel system lubrication. There would also be an improvement in emissions, similar to that of the same bio-diesel mix which is widely sold at the pump.  We reason that why go to the extraordinary bother of making bio-diesel with all the nasty chemical processes that go with a loss system only to mix it with 95% Diesel? May as well just add 5% Pure Cold Pressed Rapeseed Oil but that’s another story!

Taking what common sense tells us into consideration, I am sure that many of you will have come across some great claims on the net, on eBay etc so we will just take a little more time to explain a few further points

There are many claims by “fly by night manufacturers” of spuriously designed gizmos, “fit this widget and you can start on SVO no problem”. We say you cannot cold start on SVO without some detriment in an unmodified engine period. For instance take the lesson from above, now many so called engineers seem to think that firing up a glow plug in the fuel line will aid starting, this simply is a wildly inadequate modification. Worst still many believe this drivel. How is this even remotely possible? You have several kilograms of cold metal, tubing and fuel and a 150 watt glow plug is instantly going to set the scene for a successful start up? No way, it is just enough to un-wax a filter, granted it may be better than nothing but glow plugs are designed to glow almost white hot for short periods of time, they are not designed for fuel to run over them constantly, this is why you will find that they will fail regularly, also with such high temperatures the risk of carbon build up and break off is very high, whatever you do do not put one of these in front of your injection pump without a high temperature filter to catch any debris (please don't get confused with ATG's diesel-therm which is specially designed for fuel to flow over them, they are built to ATG's specification by glow plug manufacturers, they cannot be bought anywhere in the world other than from ATG or their approved dealers, we are their UK agents, they are used as part of a kit along with  a 2500w or more rated coolant heat exchanger). We have made very simple calculations and to be able to do what these makers claim even a small engine will need somewhere in the region of 2,500 watts of power for a clean start if used in the right areas. So 16 glow plugs in a line? Don’t think so, that’s over 200 amps on a 12v system! That’s not forgetting of course the cold veg oil still in the high pressure lines, the cold injection pump, the cold piston tops, the cold bores, the cold everything else!! The only way to make a clean start other than conversion is to pre-heat the whole engine, one way is to use a “night heater” either electrical mains or diesel whereby the engine is heated via heating the vehicles cooling system, with a few tweaks this could be a very successful way to do it but in practice it really is not the preferred method, these systems are expensive and you would need maybe half an hour of heating prior to starting at each and every cold start, the energy used is pretty phenomenal considering it is largely being wasted on a stationary vehicle, for instance if you preheated your vehicle 2 times daily, once to get to work then again for the return trip you would use the equivalent of at least 10 full boiled kettles, or over 7 days lighting for an entire house in energy value EVERY DAY!

Conversion really is THE only feasible, rational answer to running veg oil successfully. Some choose to convert the fuel. We choose to convert the vehicle. With a two tank kit, you start on diesel, run as normal and only introduce veg oil at the correct time/temp, run for as long as necessary, the system is then flushed back to diesel ready for the next morning’s start-up, this completely and neatly eliminates the above problems. In some cases a single tank conversion is possible where injectors and other ancillaries are modified to better atomize veg oil. Many millions of miles have been successfully done using these tried and trusted methods in UK and by a factor of at least 20 in Germany, indeed they already have an approved fuel standard for Cold Pressed Rapeseed Oil.

It’s up to you we can only try to help you make the right decisions, you may well reason that if the vehicle was an old banger of little value then its not worth conversion as it will probably be scrap in another few thousand miles, well yes there is a point but I really would not want to be behind you in a traffic jam first thing in the morning.

We are not selling conversions for fun, it is not a gimmick it is a genuine solution offered to a growing sustainable market. If you’re going to do it and there are many reasons why you should, do it in an informed responsible manner. Do it properly.

We have been very busy converting lots of new vehicles.

As ever we have been keeping up our Conversion Photo's diary and have introduced Hundreds more Conversion Photo's (see the What's New column to the right of this column), whilst one or two of you might not want a long list of converted vehicles with lots of shots of engine bays and pipes we are sure the vast majority of you and of course us at Dieselveg (why else would we go to this considerable time and effort, we decided even before the formation of Dieselveg yr2000 to photograph everything) want this kind of archive and consider it a valuable resource, not only because it shows many DIY'ers where to fit components and to what standard to aspire, etc. but ABOVE ALL it instils a confidence in Dieselveg that no other conversion company in the world can hope to come close to, indeed most seem to just keep on prettifying their sites without adding any real content, maybe because they have no real content, we say bollocks to the frills and lets give the customer what they want. The proof is out there in cyberspace, in our web pages, in every single photo that we publish. This is what we live and breath - laid bare for all to see. With hits in our Conversion Photo's pages running at around 300,000 per year and rising fast, we are encouraged to carry on bringing you this invaluable service. The DIY'ers section is also extremely valuable to inspire others in the pursuit of their personal goals, so all you DIY'ers out there please carry on and send as many photo's and fitting experiences as you can. To the minority of those of you who consider our photo's section a waste of time, simply do not look at them! Any comments for or against or indeed improving the service of the above please e-mail - conversionphotos@dieselveg.com
