Hey Everyone, This is for all you Mercedes Diesel car owners... For those of us with diesels up to 1999. If you are daring, please test this and see if you got any fuel mileage improvement. I did the test on my 95 E300D. I had a little problem with my fuel mileage... keep getting like 25 or 26 MPG when I should be getting like 30 average. Marvel Mystery Oil... put 4 oz for every 10 gallons... so most of us will put in about 8 oz into the fuel tank. It will not hurt your car... it is just a thin lubricant that will add some cetane value and clean out your fuel system.
I just finished half of my tank as I don't drive that much... and I am getting 30 MPG. Just before half tank, I added some Startron, an antifungal enzymes to clean out my tank of any possible fungus and next thing I know is
32 MPG... this is all local driving, very little highway driving.My friend with 87 300SDL got similar results... he finished his tank in no time as he drives alot... and he went from 24 MPG to 28 MPG in local driving too. He usually get 25 only on highway.
Just try one tank and report back... mileage... any feeling if engine runs better... anything you can tell me.
Startron is expensive, but I want you to at least try Marvel Mystery Oil... less then $5 and you can get 4 tanks out of 32 oz bottle.
