The factory recommends 5W30 for V-6 motors. Granted there's not a lot of difference but IMO I think I'd stick with the factory recommended viscosity.

oh
people! your motor will not just fall to pieces if you put an oil with a 5 point weight difference in it. let people do their research and make thier own decisions and conclusions, and if you have an opinion, like Greg here, perhaps you'd like to validate your opinion by telling us WHY it's asking for trouble, instead of just saying it.i personally use 5W30 and wouldn't think that 10W30 would offer much protection, especially at colder temps. search some forums, there is enough reading material to keep you busy for years.

The reason for the thread is... i have an '05 GT with 15,000mi on it. For the last 5,000mi i have been getting about 30sec of start-up noise. I have tried full syn both 5-20 & 5-30 the syn makes the noise worse. FoMoCo 5-30 blend seems to keep the noise down. The closer i get to needing an oil change (3,000mi) when the oil is older and thicker it's really not so bad. So... i thought if i put 10-30 blend in it might do the trick? I have taken it to three dearlers, and guess what, they all say it's normal.

I think it's bottem end, as soon as it starts getting cold outside it gets worse. Come winter time, i'm going to camp out at the dealer. But whats wierd is some time you never hear it.

Might wanna get a oil analisys next oil change. Id say keep a real close eye and ear on your engine and fluid levels. If you wanna be really scientific about it make a log of the days temp and amount of time it goes on for its intensity. My hearts out to ya and the stang, dont ever like to hear of one having problems especially ones hard to diagnose.

If you're developing engine noise, it sounds like you want to protect your warranty, stay with what Ford specs for your car. Don't give them the chance to give you the runaround because you used the wrong weight oil.

Well I may be way off here but, I would think the pump and oil flow areas are set for the 5W20 syn blend then going to a thicker viscosity could actually slow the oil delivery under cold startup. Also, I would think it might cause statring problems in the colder climates in winter. JMO

STANGSTER IS RIGHT. do NOT give them a reason to deny you when you take it in for a problem. if Ford says use 5w20 then use it.
also, use the Motorcraft oil filter too. C Y A
I used to work at Honda R & D last year for 3 years. There are reasons they specify to use certain oil wts and viscosities. there are more parts in your engine than you may think that react differently to certain oils.
they have new materials every year....so we must adapt and not think of the old ways we used to.

Wally is on the right track... These are not the push rod (loose tolerance) motors of the past. IE. 5.0 / 5.8...
The new mod motors have less tolerances or slop. They are machined much more precisely. Today's motors require the oil viscosities to be thinner in order to penetrate the tighter gaps between parts. If you your oil is to thick, it can not penetrate to lubricate properly. Motor go boom, boom.

Are you sure that's not the "bell housing rattle" issue (where the bottom two bolts are missing, causing the annoying metal-on-metal clanging on startup)?
