I haven't used this on my diesels. Not sure if it would be good for them or not, as it actually gets burned in the combustion process. It does make for quite a show on gas cars. After the car drains the can, you are supposed to let the car sit for awhile (15-20 min). Then go drive it. Remember in the old days the saying.."blow those cobs out"... well, you'll see what that means.

Maybe someone here would have experience using this product with their diesels, but personally, I have not.
