Car Forum / Volkswagen / Water Cooled Volkswagen Cars / February 2007Veggie Oil Jetta?
Can I run a 2004 TDI on Veggie Oil? I'm having a running debate about this. Thanks in advance. David Yes you can. There's numerous ways to do so. All of which can work effectively for a while to forever. None of which are cost effective for one lonely VW diesel getting 50 mpg. . Even if you get used restaurant oil for free to convert to diesel in your garage. The setup is about $3000 for primo equipment that will run your car forever. And wont trash your pump , ever. It messy and you need room. Your car of choice is also a poor candidate, Over a non turbo TDI VW. Because if you go a cheaper route, then making your own self lab tested diesel from vegy oil. And you screw up your diesel pump, its at least $800 for another used . Over $3000 for a dealer to get you one. An older A2 or A3 pump can be had for $75 bucks. If you have a diesel truck,or some more diesel vehicles. Its worth it. Unless your looking for a project. Then cost don't matter , then. The bottom line is. Its been done , Its all proven to work. There will be no issues if you do your homework and buy good equipment . Last time I looked into this it was about a buck a gallon to make real diesel. All cost included. And about 3 years return on your investment on one lonely diesel VW. Based on my driving mileage. Good Luck. > Can I run a 2004 TDI on Veggie Oil?

True. The "T" still stands for "turbo". -- Mike Smith I was guessing on the second word. I thought I was correct about the first word. ;-) >Actually, TDI = Turbo Direct Injection - the fuel is injected directly into >the cylinders instead of into the intake manifold. [quoted text clipped - 9 lines] >>> >> TDI TurboDieselInjection > Actually, TDI = Turbo Direct Injection - the fuel is injected directly into > the cylinders instead of into the intake manifold. ALL Diesels, turbo or naturally-aspirated, inject the fuel directly into the combustion chamber. That's how their ignition is timed. No Diesel injects into the intake manifold. VW might call it TDI because of the direct injection, but that's not because it's special or unique to VW engines. >> Actually, TDI = Turbo Direct Injection - the fuel is injected >> directly into the cylinders instead of into the intake manifold.

Early VW 1.6 and 1.6 diesels do not inject directly into the combustion chamber. Instead, the fuel is injected into a pre-combustion chamber where combustion starts. The burning gasses then spread into the combustion chamber. These engines are referred to as IDI for indirectly injected. Non-turbo directly injected engines are referred to as DI and turbo directly injected engines are referred to as TDI. Search IDI and VW and you can learn about them. >>>Actually, TDI = Turbo Direct Injection - the fuel is injected >>>directly into the cylinders instead of into the intake manifold. >>ALL Diesels, turbo or naturally-aspirated, inject the fuel directly >>into the combustion chamber.

A pre-combustion chamber is part of the combustion chamber. >> Actually, TDI = Turbo Direct Injection - the fuel is injected directly >> into the cylinders instead of into the intake manifold.

The "Direct Injection" refers to the fuel being injected directly into the combustion chamber instead of a *prechamber* not the intake manifold. Most Diesels up until recently injected the fuel into a prechamber. http://en.wikipedia.org/wiki/Indirect_injection nate  Signaturereplace "roosters" with "cox" to reply. http://members.cox.net/njnagel >> Over a non turbo TDI VW > >"Non-turbo TDI"? Huh? In some other markets, VW sells or sold non-turbo direct injection diesels. They were called SDI instead of TDI (S of suction instead of T for turbo).

David I was under the impression that the 04 uses a different injection system that makes it even a less likely candidate than the 2003 and earlier. Payback is pretty poor and some report goofed up injector pumps that are pretty costly. Debate might be more rabid at www.tdiclub.com |
