On every post about WVO,there is always talk about ruining your engine. Coke build-up in the rings ect. You will have to rebuild your engine. My question is-who has the most miles on a MB,running unheated WVO. I want to know how many miles before I might ruin my engine. Are talking 100000 miles before I need to rebuild? So guys who has the most and has anyone every rebuilt an engine because you run WVO.

there is a guy on the grease car forum called one tank i belive.. i know him personally and he is a nut but he says he has run 10k miles with no coking and such. rebuilding the engine should probably done when its needed .. maybe 500k miles. the coking deal can be delt with if it is true.. just do a diesel purge then follow up with some power service diesel kleen in the grey bottle or some 44k if you can find it.

Unfortunately doing a purge is not going to make the problem go away. I dont know why this is such an issue. If you want to run WVO then by all means do it, but heat the oil 160-180 degrees. I think most people who dont either dont want to spend the money or think that coking wont happen to them. You would have to save lots of money to make getting another engine worth while.

It is a pain in the butt to heat the oil. It is your opinion that you will ruin the engine.Have you ever seen an engine that was run on wvo.Then pulled the head to see what it looked like on the inside. I am not looking for opinion- I want miles and what does the engine look like.

Mercedes does a lot of testing, far more then any individual could ever do.

I'll begin to consider WVO, when I can flip open my MB owners manual to page XXX and it talks about it, and says its ok to use.

I surely would have invested $1500 in my car to get the kit from Greasel installed but I don't have the time to go around collecting WVO. So, since that's the situation for now, I won't be getting into it. Now, if some company is selling filtered WVO for a good price then I might change my mind, but as far as I know there isn't such a service -- yet!

my engine has 262k miles but only a small fraction of them are on wvo..
I have started keeping track of miles now... I drove 348 this week on wvo only and only in the fuel tank... I will keep you up todate on the miles..

This thread is long overdue. There are at least 2 distinct camps here and opinions are strong on both sides of the fence.

Even though I'll be following this thread, the fact that someone clocked a few thousand or even 10k miles on unheated wvo is statistically insignificant. Thats only 1/25th or 1/30th of the lifetime of a reasonably well cared for engine runnin on diesel.

Finally, I seriously doubt that if anyone killed an engine using WVO they would own up to it here.

I had a rusty heap of a 300D I ran on mostly WVO (heated, but not well) for a summer and fall. It was already a little tired, smoked a lot, but when I changed oil I noticed it was very sticky and reluctant to flow.

That observation was one of many that led me to make biodiesel instead.
