Oil change: synth vs. dino
i have always put standard oil into my car for no good reason really just a small money saver. i want to start using synth now but ive always wondered if the changing rulkes applied to synth as they did to dino (every 3k or so). also. should i be using what it says on the oil cap because i've been reading around this part of the forum and it seems a lot of people are using either 5-w30 or 10w-30.
thanks in advance,

Well I was thinking mobil-1. It seems to be a popular synthetic an all I see are positive comments from people who use it. How much longer does it last about and also, will this help clean up my engine a bit from my old oil?

Truth!
and there are hundreds of UOAs on the internet to prove your statement.
Original Poster:
Conventional oils (group II petroleum) and synthetic blends (group II blended with a little group IV) are good for 5,000-7,500 miles. Motorcraft syn/blend, etc...
Cheap synthetics (group III hydrocracked - highly refined petroleum) are good for a 7,500-10,000 mile change interval. Pennzoil, Mobil 1, Castrol, etc...
True synthetics (group IV PAO and V POE) are good for 15,000 or more, depending on the formulation. Red Line, Amsoil, Royal Purple, Mobil 1 EP, etc...

lower NOACK volatility (less burn off and evaporation)
higher levels of ZDDP (anti-wear additive)
lower friction (no impurities in the base stock)
lower heat (because of less friction)
etc....
