Don't think so Rudi. My supplier has quite a network of restaurants that supply the 'waste cooking oil'. In the summer I run it straight (B100) in my IH 444 (7.3 Power Stroke), has a hint of fried clams and donuts in the exhaust. It sorta turns to pudding near freezing, so I pretty much use petro diesel in the winter. There is no 'road tax' in RI if it's made here, so it's more than $.30 a gallon cheaper. http://newportbiodiesel.com/
It is a very good cleaner, but will remove some paint and it didn't play well with the old cooler I used to wash the tranny parts.
