i have a Question about Duralube, ProLong and all those other Aftermarket oil additives
Are they as good as AmZoil? they swear up and down that they are the best, and that they make the break down of oil less and last longer.
any Experience with them???
They are all crap and gunk up your engine. The only product that I had sucess with is the Engine Restore which you pour in your car to relube the seals in the engine and make compression better.
