What exactly do you mean by a a real heatexchanger?

A heat exchanger before lift pump.try omarsales .com Love Crtaft never got the oil hot enough.Thats why I have injection line heaters also.

Basically you need to heat the VO to burn it correctly. People shoot for 160*F. There are two options for heat, coolant and electric. Coolant typically isn't not hot enough to boost the VO temps enough, so most people have electric heat as well. I have a coolant tube through my VO tank, coolant lines bundled with my fuel lines from the rear to the front, a coolant heated fuel filter, and a midranger coolant heater(Arctic Fox brand). For electric heat I have a vegtherm, and injector line heaters. I'm a big supporter of injector line heaters. They boost the VO temps after the injection pump so you're not heating up the IP a ton.

Depending on what Lovecraft system you ended up with, the only heat you've probably got is a coolant heated fuel filter. Which only heats once the engine is warm. So in the morning you've got fuel lines, fuel filter, IP, and injector lines full of cold VO. Cold VO = DEATH to the engine.

I think your poll is missing an option.

*Keep system and add to it/improve it.

Many do not agree with the lovecraft system. In a warm climate it will work although not ideal over all.

If you wish to continue using vegetable oil, consider adding a second tank whether for diesel or veg oil, but either way, the best method is 2 tank. You'll need switching valves and additional fuel line.

There is alot of emotional opinion on the subject. If you have no use for the equipment, remove and sell. Consider flushing the fuel system regardless.

best of luck.

Consider updating your profile to show location, and year, make model info in your signature.

Alright, so how would I add a switch to change from the main diesel fuel to the vegetable oil. I've seen these in kits, but would it be easy to make one my self?

Also where exactly is the heat exchanger placed? This is what i got in mind:


VO(Warm engine) Diesel(cold engine) ->(switch)-> heat exchanger -> pump -> injection lines with heaters

My lovecraft seems to have the lines from the radiator going around the engine in a sort of loop with T connectors.

So theoretically the Love craft isn't really that bad of a system, its only gets a bad rep because its missing some essential components?

Here is a flow chart of my VO system. Some folks loop the return fuel, back into the IP instead of sending it back to the tank. This can cause problems when you get air in the system. It can be hard to purge out, but others don't have a problem. The looped return has the benefit of keeping the hot oil in the engine bay rather than sending it back to the tank and having to reheat it again.

no offesnse, but you really need to read more. There is so much info about this your brain will explode. Try Youtube, most videos suck, but you'll get the point. There is so much info available.

You could build a space ship yourself if you had the ability. But why not just buy the valves. $50 each at Greasecar.com OR go the manual route and use ball valves and switch over yourself. The electric valve method is superior though.



IN the engine compartment somewhere. Plumbed in prior to the diesel/VO switching valve.


Once you better understand the 2 tank system you will add elements to your flow chart above.


Bingo !

(But really its missing more than half the needed components, that is why it gets a bad rap from those that support VO as fuel)

Keep in mind there is a contingent of enthusiasts on this site and else where that feel that VO is the death juice from the devil himself. Many wouldnt use VO as fuel if it were handed down from God himself.

make your own opinion.

That's why I created the alternative fuel forum! to keep the members that use want to use VO softly buffered from those that don't use it.

win/win!

After doing a decent amount of research, I can say I have formed a well educated opinion

I am somewhat against WVO now, I am now planning on trying to run a Bio diesel processor at my house. I was thinking about selling my lovecraft system in order to gain some money for my biodiesel processor. Does anyone have any good plans for making your own homemade biodiesel processor?

Actually, from what I can tell about 98 percent of participants in Mercedes groups on the Internet.

Regrettably there was for quite a while a steady stream of Craigslist ads for Mercedes diesels that had, indeed, been condemned to early deaths by half-wit experiments with WVO/SVO. (I bought one and tried to do CPR, to no avail.) This supplied the denyers with weekly fodder for ill-informed quips and sarcasm.

I have run 100% WVO in all my Diesels for years (about 8) now with no ill effects. Weather permitting of course. Granted I live in a much warmer climate than you do and that helps greatly. Most of the people who fail at WVO usage have no business opening the hood of a car. That's if their lucky enough to get the hood open.
The same people seem to always have "bad luck" with cars or mechanics but don't seem to recognize the common denominator, THEM

Fattyman I agree.
There are others out there that have had great success running WVO in their 'Benzs.
Many thousands of trouble free WVO miles can be had from these cars if the proper equipment is used/maintained, and the oil is filtered properly.

I have an 87 300sdl with LC installed. I used WVO for about a year. I got the oil from a local sushi joint. I filtered it and it was very labor intensive. The car ran fine for a while, and then the car would have a lot of trouble climbing hills (Like a VW bus). I determined that it was too labor intensive to run on WVO gathered from my local sushi joint and it very messy. At that point I switched to just straight Diesel and asked my mechanic to address the power issue. He cleared out something in the turbo (not sure), but it had some get up and go after that. Now I am leaving a puddle where ever I park. The puddle is diesel leaking from the Lovecraft convertion. I want ot go back to stock. Any advice on how much work this is and how much I should expect to pay?
