5w-30 is whats recommended. I think it says it under the hood somewhere. My Mach has 5w-20 (not sure why the newer model require thinner) written on the oil cap.

I have a question as well if ya don't mind a little high jacking.. I'm looking at doing an oil change on my cobra today, which oil would guys recommend for a 131k mile 5.0 engine, also I was planning on buying a can of sea foam to put in the crank case to give her a lil cleaning before the change, how many miles should I drive with the sea foam in the crank case?

I recommend Mobil 1. It's a very good oil.

I ran seafoam through the oil once on my Cobra. I put it in the night before I planned on changing it and drove around that night, probably around 50-60 miles. Changed it first thing the next day.

How did it act? I have been reading to run it through 3k miles or so, seems a little to long too me. Also what weight should I go with?

 

[CY98Cobra]

You couldn't tell it was in there. No unusual noises or noticeable change in how it ran.

3k seems a little long to me too. I don't think I'd go over 500 miles before changing.

What weight of oil? I believe 5.0's call for a 10w-30. I could be wrong because it's been a long time since I've messed with anything other than a modular.

Ford changed to a thinner oil for one reason only...C.A.F.E.(combined average fleet economy). The thinner oil gets better fuel economy which helps meet strick gov't standards.

I use 10w30 Mobil 1 and it eliminates blowby.

German Castrol 0w-30 may just be the finest oil around my friends.

I looked for the German Castrol here but can't find any. It's all made in America.

I buy my German Cstrol from this merchant when the AutoZone near me doesn't have any. The webiste is down today, but they definitely have the 0w-30 German Castrol.

There's a very reputable SVTP member on here, his name is QUADCAMMER and he has done plenty of wear tests in the 0w-30 German Castrol to show that it protects significantly better than the other motor oils out there. His results are legit as far as I'm concerned and won't spare any cost for my baby.
