1984 MERCEDES-BENZ 300 TURBO DIESEL, 1978 CHEVROLET K20 CUSTOM DELUXE
Hello, i just changed the oil in my car with amsoil 15w40. I was amazed at the sound difference with the full synthetic. The motor feels more cushioned and i feel good about high rpms with the high quality oil. I use this oil in my tractor and i keep that at full rpms for hours while i use it and it runs great. I highly recommend this for anybody looking for an excellent high quality full synthetic oil for there diesel or gasoline car. I was lucky enough that my local Napa stocks the stuff. I have not seen it anywhere else so i assume that most people will have to order it online.
