You have to watch out just because it says it's a synthetic doesn't mean it's a true synthetic. Oil company's like to claim their oil is a synthetic when it is actually petroleum base. Pennzoil and Royal Purple are such oils. I don't care what you use just make sure you know what you're truly getting. I use Amsoil and Amsoil filters I've used them for years and from the research I've done it's the best on the market made 100% in the U.S.A. It's one of few true 100% synthetics on the market another one is Mobile 1 which would be my second choice. As far as filters go first choice would be Amsoil their filters are a 4 micron filter. Next would be Royal purple, Wix, Purolator pure one. Last would be Fram or K&N they are below average at best.
