    Adam’s ceramic coat

    Update on the ceramic coating. We haven’t had much snow thus far but still had a bunch of salt on the roads. I'm amazed at how it’s holding up. You won’t be disappointed.

    OBD2 reader/scanner

    I’m looking to get a new reader with more capabilities. Specifically one that can relearn tire position and reset the parking break along with ABS function. Does anyone here have suggestions on brand and models? Thanks

    New to forum, looking for info on the duramax mileage

    My Yukon XL has a lifetime average of 27.5 for 7750 miles. My best tank was 31.5. Now that it’s cold out it’s a little worse. I haven’t towed yet.

    Air bags for 2023 gmc Denali 1500

    Question. My boat and trailer weigh in at 6600 pounds. Do I buy the 8000 pound capacity hitch and have some room for heavier loads?

    Adam’s ceramic coat

    Since my Yukon was new and never waxed all I had to do was wash it really good. If you have some miles on you're vehicle they say to wash with something that will remove any wax and then clay bar it. Bottom line a clean canvas. The tough part for some might be that you have to do it in the...

    3.0L Overall

    So there are a lot of people out there that seem to have a variety of issues from rear main leaks to long crank issues and a few things in-between. I was told once that bad news travels at the speed of light and good or no news tends to stays unreported. So the bad news has me a bit nervous but...

    Adam’s ceramic coat

    Update on the ceramic coating. Great stuff! Holding up way better than any polish or wax I've ever used. Winter will tell the true story.

    Not feeling good about the PF66 filter

    Not really. A bit disappointed. I'm good knowing I have better filtration but still.... On the plus side I'm really happy with the millage this thing gets. For a 6000 pound truck it's great. I haven't towed yet but so far my lifetime average is 27.4 (4900 miles). No EV in my future.

    Not feeling good about the PF66 filter

    Yes. I already have the sample kit. Going to give it another few thousand miles and send it in.

    Not feeling good about the PF66 filter

    I'm a bit concerned about the filter being the low but I don't really have any other options. I'm thinking about putting a shield around it. As far as cleaning up the oil it has cleaned it up some but not as much as I had hoped. I did some research and found that particulate size is .5 to 2.5...

    Not feeling good about the PF66 filter

    The bypass filter is supposed to filter at 2 microns. We’ll see?

    Not feeling good about the PF66 filter

    I have only driven about 300 miles since installing the bypass. No significant difference. Hopefully more miles will yield a measurable improvement. I’ll keep you posted. Does anyone know what the particle size of the soot would be?

    This might help to understand how this system works.
