I bought a new van to me. It is a 2002 E350 van with 135K miles and runs like a top. I've only put about 2K miles on it with valvoline 5w 20 syn. and it is doing great. I would like to switch to amsoil (or other extended drain) oil. I'm thinking I'll use the amsoil filter too. I will put about 50K miles a year on this vehicle. I'm leaning towards the ASM 0w 20 and the first drain around 15K or so for an UOA. What would you guys use?
Thanks,
Chad
