I live in ny and the weathers been hot and i'm going to the strip the next 4 weekends and i'm due for an oil change what weight should i use. I normally just run mobil 1 5w30 but i was told for going to the track i should run mobil 1 15w50 what do you think. I'll end up doing another oil change at the end of the month just becuase it will be a hard month.

I don't see any problem running regular 5w-20. I mean, think about it. When you floor it on the highway and tach it out are you worried about your oil? Same thing as going to the track. You should be alright.

I would run mobil 1 5w 30
i really dont like the 5w 20 crap ford says to use and neither do the mechanics! The ford dealership i live near has had 8 engines this summer come in due to lack of viscosity during hot summer days. The 5w 20 thins out too much in hott weather

I agree with Modular2v. I don't think the 5w-20 Motorcraft would be good enough for track use in the hot weather. Mobil1 makes some decent stuff and their 5w-30 oil is probably thick enough. You could always try Mobil1's European formula oil that is 0w-40 in weight. I'm sure it would work good if you wanted to try it.

Personally, I'm an Amsoil man and I use Amsoil 5w-30 with no problems at all.

Keep the 5w-30 in it and have fun racin'. You shouldn't have any problems with that oil. After trying AMSOIL's 5w-20, 10w-30, and now the 5w-30, my car seems happiest with the 5w-30.

I'll let the warranty run out before changing to a 5-30.

merc they are not going to void your warranty for running 5w 30 instead of 5w 20..... before 2001 ford required no less than 5w30 be put in their engines! the last time i checked the rods, crank and pistons havent changed much in the 4.6 since 2001...yes i know there are 6/8 bolt cranks and such and yes i know there were windsor blocks b4 2001 but you get my point

They can not void your warranty for running 5w-30. If they try to, they must prove it is what caused the problem that is under dispute. Many people also assume that when using a Synthetic oil and synthetic oil filter, you must change it every 3-5k miles to meet OEM specs to keep your warranty. This as well is false. If you are using a synthetic motor oil and synthetic filter and Ford(or any other company) trys to void your warranty for this, they must prove the oil is bad and it not being changed by proper changing intervals was the cause of the problem. This can be solved by a simple oil analysis. If the oil analysis proves the oil is not contaminated and it was not the problem, then they can not deny your warranty.

There is also a debates that have been done over at Modular Depot concering 5w-20 being too thin in certain applications and it has resulted in motor damage over a extended period of time.
