    20% OLM sounds like a reasonable spot for a warranty plan

    '23 GMC 6.6L GAS - Oil Analysis and OCI Questions

    Thanks for the info. What was the reason you went from a relatively new '21 to a '24? The '21 is a very nice truck.

    Sounds like we have similar uses....towing a TT in 100F+ temps, towing my fishing boat weekly, plus all other common truck uses! When I purchased....I drove the truck home 150 miles from dealer in 119F!!

    '23 GMC 6.6L GAS - Oil Analysis and OCI Questions

    I'm new at this oil selection/analysis, as I have not purchased a new truck in many years where I can service and record from new. I want to take great care of my investment, as best I can: 2023 GMC Sierra 3500HD; 6.6L GAS/6 Speed Trans; 4x4; Crew Cab; Short Bed After doing some reading on the...

    Thanks! I was a Ford guy and this is my first modern GMC. So far, I like it! Probably my last truck, so I want to maintain it as such (severe duty maintenance).

    Mobil 1 - Advanced FS VS Truck/SUV for towing?

    Perhaps I should also consider EP....it's just that Truck/SUV claims it is for higher temps when towing

    2023 GMC 3500HD-6.6L GAS/6Spd Trans - Motor Oil/Filter Choices?

    10 speed trans became standard on 6.6L Gas in 2024. I specifically wanted the 6 speed.....more simple, proven durability, and less expensive to repair when the time comes...because it will come

    2023 GMC 3500HD-6.6L GAS/6Spd Trans - Motor Oil/Filter Choices?

    The same thing happened to me about 8 months ago on my previous truck. '03 F-350 V10....Motorcraft FL820S oil filter...leaked at seam....my first time ever seeing this! I, too, change my own oil for 44 years and have never seen this!
