I have a 2007 GMC 5.3 truck that has just over 80,000 miles on it. ABout time for an oil change, and was wondering what weight of oil I should put in it for the winter?

Or, can I run 0W30 all year and not worry about it?

Thanks!

I run mostly 5w30 in my 5.3L & did one round of 0w-30. Either will work just fine...

There are very few 0w30 oils available in the States but the most appropriate one would be Mobil 1 Advanced Fuel Economy 0w30 and yes you can use it year round.


Just to be sure for the sake of the OP's engine, he's done 80k in ~6 years, which is about 13k a year (might be less, might be more).

If you are going literally year round, then for 0w30, Mobil only recommend you go to the manufacturer's oci.

Mobil 1 Extended Performance 5w30 on the other hand is guaranteed for 15k. Mobil also refer to EP as Ultimate Protection as opposed to Superior for the AFE so it's a tier higher (in marketing at least!)

There is a great deal at Pep Boys for the more exotic Mobil 1s right now.
 
M1-Good choice on oil--Say LocoEngr, I used to live just north of you up in Montana in the Shields river valley and used to do some hunting down in the Bighorn mts. and had friends that once lived in Ranchester.

Welcome to BITOG!

Yes you can use 0w30 all year, but the only readily available 0w30 is Mobil 1. It is awesome stuff.

NOTE: Castrol also makes a 0w30, but it is on the very thick side of 30, almost a 40. It is often referred to as GC or "German Castrol" here on BITOG. But remember you probably DO NOT want this oil. It is only sold at Autozone.

These are the only readily available 0w30 oils that are sold in stores.

Mobil 1 0w30 is perfect for you. However, any synthetic 5w30 should do, especially Mobil 1's own 5w30.

Good luck!

You certainly can, as others have indicated. Are you running synthetic already, though? If you're running a synthetic, there are few reasons not to switch to a 0w-30, considering the truck is likely past warranty, eliminating any concerns about the GM numbered specifications. If you're running conventional, though, there's not a lot of reason to switch to a synthetic 0w30 unless you're planning on extending your OCIs or do a lot of unaided winter starts.
 
I'm sorry but I have to again sound a note of caution as several people have said unequivocally that Mobil 1 Advanced Fuel Economy 0w30 can be run year round.

The OP could be doing 13k a year. Mobil 1 Advanced Fuel Economy 0w30 is only warrantied to manufacturer intervals.

Mobil 1 Extended Performance 5w30 however is warrantied to 15k.

It is also Dexos approved, has a higher VI, lower viscosity at 100c and 40c (can't find it's MRV at -40c).

Compare for yourself:

You won't find an MRV at -40C for it because the MRV for 5w oils is listed at -35C.

OK, can't find an MRV full stop!

I thought he meant year round as in all year, and not for a one year interval. If he plans on following the owners manual for the oil change interval suggested there, them IMO Mobil 1 Advanced Fuel Economy 0w30 is the better choice.

One could always request that data from XOM, but my experience with this process is that they aren't all that forthcoming unfortunately.

Agreed in that case. Indeed, I read Wyoming but not Minnesota in the title, so Mobil 1 Advanced Fuel Economy 0w30 could come into it's own if Minnesota hits it's record lows of ~-40f/c.

In fact, the OP should advise if he expects the car to get up to temp or not in winter. If not, would he be even better served by Mobil 1 Advanced Fuel Economy 0w20?
 
A friend of mine lived and worked in Sheridan, Wyoming years ago. When he was living in Sheridan, he bought a new Mercedes from a dealer in Denver. My friend would only let the dealer in Denver do his oil changes on the new Mercedes. By the time he drove all the way down to Denver and then drove back to Sheridan, it was almost time for him to get another oil change!
