How can that be? The oil pan is the same across all the years.

Dipstick. Not you either. The literal dipstick. They changed from year to year. At least thats what we've concluded in another thread after making the comparisons. I think there was also a oil pan depth change sometime, not sure though. Rjstaaf made the comment about it. You can refer to the thread, it should still be floating about.

I'm confused on my 2002 GT... the oil filler cap says 5w-20 in big yellow letters.

??? so is this or is it not the correct grade of oil?? You guys seem to contridicting each other???

I agree it is confusing. I do know that Mobile 1 claims, directly on the containers of 0W-20, that it is 'approved by Ford as replacement for 5W-20'. I saw that last night when I went to Walmart checking Mobile 1 synthetic oil prices.

With that said, I've heard people in newsgroups say that the old Ford recommendation for oil for the 4.6L was 5W-30, but the reason for the change in recommendation was that the 5W-20 is less of a polluter, as per the EPA. So it was apparently pressure from EPA to change from 5W-20 to 5W-20, but 5W-30 is actually a better oil, better for longer engine life(just not for the environment). I've decided to stick with 5W-30.

If I was in the north, I'd definitely consider 0W-20 based on what people have been saying in these newsgroups.

the only reason ford has switched to 5w20 is to get slightly better gas mileage for cafe requirements. too thin 5w30 for me mobil 1. once break in is completed.

I for one have used 5w 30 synthetic since new.
I just read an article on oil at this site where they do talk about the lighter weight oils lasting longer, have a look.

So what's the verdict then, if your car tells you to run 5w-30 on the cap that you should be running 0w-30 if you wanna stick with synthetic, or 5w-30 synthetic??? I live in new york where it gets below freezing, but i never drive the car in the winter. sorry but this thread is just confusing me??

As for your brother, has he played with his ECU? In front of the ECU are 3 wiring harnesses. One of those harnesses lets the Oil Pressure gauge work. Make sure they're all snapped it.

5w-30 is a multi-viscosity(weight) motor oil where as 0w-30 is a straight weight motor oil. I dont think there is really an advantage to running one over the other but you can buy each in fully synthetic. Take your pic.

If you dont drive your car is severe cold weather, then a straight weight motor oil will be fine. Straight weight oil is "supposedly" better for performance applications since it offers superior protection under harsh race conditions as opposed to multi-viscosity oil.

These oil threads always make me . How about someone tries 3qts of 0W-20 and 3qts of 5W-30 and mixes them together?

I like the Amsoil 0W-30 oil. I've used it exclusively, and I've never had any problems (30,000 miles so far).

For a multigrade oil, the first number is the viscosity when you first start the engine. You want this number to be as low as possible, so that the oil will quickly flow to the moving parts. "0" is always the best for the first number.

The second number is the viscosity after the engine has finished warming up. The best number for this second number is debatable, but probably 20 or 30 is fine for a late-model Mustang GT.

An Amsoil tech told me that Amsoil 0W-30 is far superior to Amsoil 5W-20, so I use the 0W-30.

I like true synthetics, because they have a higher film strength than dino oil, for better protection of moving parts.

What is with you guys? Are all of you some kind of oil scientists or what? What do you mean by "it seems to be too thin" or "I haven't had any problems" since I changed oil. What is too thin? What kind of problems were you expecting? If you use a high quality oil like Mobil1 0w20 and they say on the bottle it is recomended for new Fords, don't you believe it? Take advantage of the newest technology to give your engine the best while you might even pick up a few horsepower. If you can't get with it, go back to using straight 50w like they did in the fifties! Geesh!!!
