Which engine oil do you use?

Walmart always has a sale on mobil 1 full synthetic-i usually get a 5 quart jug for 22 bucks.I do use rp for oil filter.

Whichever named brand full synthetic is least expensive, but a few dollars isn't of concern. Generally Mobil 1, Valvoline or Castrol. This time at 93,000 I decided to try high mileage version hoping it might help preserve the oil tight condition. Actually did it at 25% oil life remaining on the DIC to beat the winter weather. Just in time because it's 35 degrees and 30 mph wind today.

I'm not a fan going by the oil life DIC, mileage is what I go by.
Usually every 6K or 12 months which ever comes first.
On my 07 Yukon Denali 6.2, I use Castrol synthetic blend 5w30, GM specs suggest 5w30.

Maybe it's our usage of the Chevy but the DIC always shows a change due quite a bit before 6,000. On the other hand, our other car tracks the miles and notifies at the set mileage rather than try to judge what kind of driving we do.

Full Synthetic. Valvoline High Mileage, usually.

Well... craft or not, Blue Ribbon is the best beer.

As for oil, in the 06 Tahoe 5w30 orielly dino juice and delco filter. 126k miles

06 Silverado Delco filter and currently 10w40 orielly conventional as a test to see how pressure does over the life of the oil change. 5 or 10w30 doesnt carry the pressure I'd like to see when hot after about a 1000 miles. But the truck also has high mileage and before I got it, was driven a while with a bad oil pump oring so I'm sure the bearings arent in fantastic shape. But its always had orielly oil since new and it's made it to 400k so the oil cant be that bad.

My 95 F150 5.0 coming up on 300k gets oriellys sae 40 in the summer and 10w40 in the winter and a Motorcraft filter.
Another truck that wasnt cared for before I got it. 150k on it when I got it in 2010 and the original plugs were in it along with the original wires ( had the date on them from the factory). Oil was water thin cold so I cant imagine what it was hot. If I run anything less than some sort of 40 weight it holds 25 psi at 2000 rpm and 10 at idle vs 45 and 25 respectively.

So, unless it's on stupid clearance like the case of Pennzoil sae 40 I got for $11 I dont run fancy oil just good filters.

Lots of idling and city driving?

You only drive 6k in 12 months?
