Your Preferred Motor Oil?

Isn’t it 5-1/2 quarts with the filter?

 

[OR VietVet]

I use the taller filter but I have always added 6 quarts with no problems.

The 5.7 takes 5 quarts and the 5.3 engine takes 6 quarts.

OK, that clears it up. Thanks, Vet!

I switched to Triax Fluids over a year ago. TRIAX LUBRICANTS Available on Amazon.

I use the TRIAX SYNERGY SRT 0W-20 Full Synthetic (triaxlubricants.com) in my 2016 Tahoe. (8 quarts)

2015 5.3 takes 8 qts

Hi Everyone. One quick actual experience:

2012 Tahoe 5.3 200K miles. I noticed lower oil pressure at idle after about "50% oil life remaining". I had used Castrol Edge full synthetic and Fram TG filter.

Based on a recommendation here a few months ago I switched to Mobil1 and the Mobil1 filter. The comment (I can't find) said the Mobil1 filter was superior. Now at "10% oil like remaining" the idle pressure stays the same as when new. (I usually change at mileage and 20% remaining, but I just did a long trip and was at 10% when I got back.

THANKS for lotsa help I've gotten on this group!

No one has called me on it yet but I use the Amazon basics 10w-30 full synthetic with absolutely no problems. Made at the same plant as Mobil 1 and in side by side tests on numerous sites, it either has tied Mobil 1 or beat it in many tests.

But yea, another "what oil should I use" thread. Yawn!

Has anyone really ever had a problem with any oil that they are aware of? Any oil will get you through the first 100k and by then nobody knows why anything happens

I usually use olive or canola oil and i have a rubber hose with a hose clamp where the filter should be. Then i have the other end of the hose hooked to the oil pick tube. Works great

Heated topic...

Mobil 1 in gas engines.

I switched over and have been running it for as long as I can remember now (20 years?) never an mechanical engine issue since, in multiple trucks and cars, high mileage and working trucks.

That’s my 2c.

Hey i have a 01 yukon 5.3 and was using 5w30 castrol/castrol high mileage since like 2009. Just in the past year or two i switched to castrol full synthetic high mileage. Never had a problem with my oil pressure, it would usually run around 40 at idle. Mostly used k&n and puralator filters. My vehicle is at 331,000 miles.
What weight oil are you running?
