I just bought my better BHAF nanfiber air filter and was going to pickup some amsoil for my next oil change but drew a blank on which weight to use. Currently the truck has 179,000 and I run Valvoline PB 15/40 and change it every 5,000. If I were to go to Amsoil, which weight 15/40 or 0/40 or 5/30?
Thanks
Chris
