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

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

    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!

    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?
