It was my understanding that 5w-30 was a thinner oil than the 10w-30 and there for gives better MPG because it is easier to pump and move around than a thicker oil.
I dunno.... im just talking out my bum hole
Probably wouldnt make any difference

My 97 Silverado has had Mobil1 10W-30 in it for 9 years now since the 1st oil change and runs great with the original engine

everyone knows that the cap says 5w-30... but if you read your manual (it's that instruction book looking thing that came in the trucks glove box) it actually tells you that in warmer climates it is acceptable to use 10w-30. it's amazing how much research you people do without starting with the very basics first... hell, put the manual on the back of the toilet tank for a week, it makes decent reading material
Down here we may see temps below freezing 3-4 times a year for a couple of hours at a time. By using 10w-30 it may help with some of ya'lls oil consumption issues. Don't get me wrong, my truck uses a little, but it's barely noticable.

I've been using 5w-30. Have 29,000mi now. Engine uses no oil between oil changes.
Both 5w/ 10w-30 weight engine oil will get to a oil viscosity of 30 when the engine is at operating temperature.
So the comment about using 10w-30 to reduce oil consumption is void. The last number would need to be 40 or more to reduce oil consumption.
At start up the engine oil that reads 5w-30 will be at a viscosity level of 5 until the engine warms up. It is great for colder climates. The oil stays thin until the engine gets up to temp.
The oil that reads 10w-30 will start out at a viscosity level of 10 until the engine gets up to temperature at which it eventually will get to the viscosity level of 30.
So, down south (Where temps stay mostly warm) for 3 seasons, you can use 10w-30. During the winter season you might need to go to 5w-30.
I'll just use the 5w-30 for all 4 seasons.

I just use Mobil 1 5w-30 all the time, and it does use a lil oil inbetween changes,, but thats because it gets the crap run out of it.
My friend uses Delo 400 15w-40 in all their vechicles 93 Suburban 350 w/250k miles with 0 problems, 2001 Suburban 5.3, 2004 1500HD 6.0, 2004 Z71 5.3. and all their tractors, 4wheelers, Cotton pickers, Corn pickers, they get it by the 55gal drums so thats just what they use in everything.
Around our house we use Castrol GTX 5w-30 in my moms camry and sisters camry but my truck gets Mobil 1.
my brother just mixes what ever oil he can find for his 77 chevy.. yea he is a genious.
