Is there really a difference, formula-wise, between "Diesel Purge" available through most of the mail order places and just using straight fuel additive like Diesel Kleen available right around the corner?
My car is running great, at least I think, because I don't have anything to compare it to, so I just want to clean the injectors for the first time. Also, any pics of the infamous banjo connector that I should be looking for an cleaning?
thanks!
