do you guys run 5w30 like recommended or 10w30?

2003 SIERRA- 5.3 DD
1985 SWB C10- slow, future plans- shaved, painted, 6.0/4l80e
Whats the benefit of running 10w-30 as opposed to 5w-30?
2010 Silverado ECSB LS 4x4. Only mods so far are a K&N drop in filter and a Rough Country 2" front level kit
10-30 is a thicker oil, better suited for hot temperatures. 5-30 is a thinner oil used in cooler temperatures.

i gotta say, my 4.8L has 117k miles and it doesn't burn a drop that i can tell
and i check it every week religiously. the only problem i've had is one super noisy lifter

Well, I live in a rural town about 40 miles west of St. Louis, MO. Out temps at times range from below zero in the winter to low 100's in the summer. Change oil weight depending on season or just stick with 5w-30?

10W-30 will cover you for all those temperatures.

Might want to bump it up to 10W-40. This summer I'm probably going to switch to 10-40.

I have always used 5W-30 Mobil 1 in my 5.3. Got 153,000mi on it with only minor problems. Some of the new Toyotas I work on spec 0W-20 for the climate here in NE Texas.
Alot of it has to do with the amount of bearing clearance and not just temperature. The less bearing clearance your engine has the thinner the oil must be to maintain the proper flow through the bearings for cooling and lubrication. The more bearing clearance your engine has the oil will have to be thicker in order to maintain the oil film that hydraulically protects the bearing surfaces from metal to metal contact under the pressure from the combustion process. To sum this little bit of knowledge up I would recommend running what ever was speced for your engine from the oem manufacture or the bearing manufacture on a rebuild.

Good point, I didn't even think about the clearances.
