Reccomended Oil For 2001 yukon

[quake.9999]

Hey all,
Any recommendations for motor oil for my 01 4x4 with 140k, Im thinking full synthetic but are the high mileage oils worth a look.

I use Mobil 1 High Mileage 5W-30.

Shell T6 synthetic gallons for $21 at walmart, best oil for the money hands down!

Just curious, why would you want to run heavy duty diesel oil in your Tahoe?

I don't like syns in engines over 100k, seems they make leaks way worse. I run Pennzoil a lot, so I choose Pennzoil Platinum for the SS (40k on engine), and the Yukon and Durango get P High mileage in the gold bottle.

Synthetics only find leaks that are already there. Being they are made of uniformed molecules they are able to exploit weak spots in the gasket materials. This can happen with an engine that has 10 miles on it or even 100 thousand miles. So that part does not matter. I have several vehicles with way over 100k running on synthetics and none of them have leaks.
