ok so i have an 07 mustang v6 and i do all my oil changes the car has 6k miles and im wondering if i should stick with using motorcraft oil for the engine or should i spend a little more and get something else?

just get some 5w30 synthetic, Mobil 1, amsoil, Reline or RP

Mobile 1 5W30 full synthetic.
that is the only way to go.

[sm=headbang.gif] ... another oil thread... Oy vey.

Amsoil, Royal Purple, Redline and Mobil1 are some of the oils favored on the forum. Just be sure to match it up with a decent filter. PERSONALLY, I use the full synthetic to extend my oil change frequency (use the search before a thread war starts on THAT topic) but I consider the oil filter to be the more limiting factor.

However, there's nothing wrong with the Motorcraft synthetic blend that Ford puts in our Stangs.

No kidding, unless you're driving your car hard or have a lot of hp or don't want to change it that often. Just stick with the synthetic blend, it's fine. But if you do want to switch up to a synthetic, run RP with a Motorcraft filter.

just to liven up an otherwisemundane which oil should I use post - over on another forum there is a discussion as to whether using oil other than Motorcraft will screw up the variable cam timing in our cars. Anyone care to chime in on that?

I doubt that. The 5.4 uses the same type of system, I believe, and I can personally account for someone using Mobil 1 for the life of the vehicle and they are 200,000+ miles.

I've done a LOT of research on the function of the variable valve timing system and it appears that it is more oil "pressure" sensitive than sensitive to oil weight. Granted, a heavier weight oil will increase oil pressure but if you stay within a 20-40 weight I don't think it's going to affect the system. Personally I'd stick with a 0/5w20-0/5w30.
