Book calls for 5w 30. I read I should go heavier with older engine. At 5w 30 I'm buring a quart every few thousand miles? Thanks

5W-30 synthetic. Mobil 1 is just fine. A quart in 2000 - 4000 miles is well within the GM curve for a relatively NEW engine - with less than 36,000 miles.

5W-30 as specified/ with proper spec (GM4718M or dexos-1). Can try a high mileage formulation to see if it decreases the loss.

I like and agree with the two comments that follow your initial post.
I REALLY LIKE THE 160K.

Wonder how much gas was burned!?!?!?

Well, a 2010 model with 160Kmiles goes about 18,000 miles a year so it's a road/highway car. Get a good -V moderate load road mileage figure and use that to calculate approximate gallons used.

Just for shits and grins, the 2018 actual cost to own/drive a vehicle was about 71¢ a mile. That includes gas, oil, insurance, normal maintenance. So that 100 mile run you just did cost you $71 in the long run.

Mine has done 17.16 mpg, calculated, over 29,962 miles. The ECM's opinion differed by -0.26%. That was with mixed driving - semi rural - moderately well behaved - no winter - auto with 3.73 diff.

9411 gallons at 17mpg or 14,500 gallons at 11mpg! Possibly 16 sets of tires. THAT'S LIVING!

Might that be about 227 gallons per tire? ie: 14500 gallons / (16 x 4) tires.
A todometer would be useful!
