well... I'm knew to biodiesel... and I just bought this car... here in nocal we have several available biodiesel outlets.... I assume these biodiesel places are using some sort of filtered vege oil It seems to suit my car just fine although the price is .50 higher than regular diesel
per gallon that is...

but I imagine that might change as the economy might get better.... I don't have the ability to do the waste oil thing... only bio or real desiel from someone who sells it... it seems I get 25 mpg on the bio or maybe better but not much i'm not sure arab oil will get better mileage....from my past experience with 300cds

thanks for you input... i think the additives are just intended to clear the injectors and maybe boost octane a bit but what do I know!
