I run synthetic and usually still change it around 3k miles. I really don't worry about it if I'm a coule hundred miles, but whats 40 bucks for oil and a filter, it's just added insurance.

Why I ask is because I put a new stroker in my truck. I spent quite a few extra bucks for the forged and internally balanced engine, so I want to treat it right. I am about ready to change over to synthetic, but dont know which grade to choose. The engine is new (only about 3.5k miles) I am currently running Mobil 5w30 dyno oil. Oil pressure at cold start up reads at about 60psi on the gauge, and settles down to around 40 after being warmed up. On very warm days oil presure will settle down to 25-30psi according to gauge at idle. (not sure of accuracy on the electric oil press. gauge) What grade and type of oil do you guys reccomend? I hear that Mobil's 30wt oil is on the thin side, but dont know any other alternatives. Would running their 10w30 be better even though its a new engine? I plan on doing oil analysis in the future and see if they reccomend anything also. Thanks for the help!!!!
