    2018 Chevy Duramax L5P - 6,400 miles 37,800 miles total - Oil not changed

    I am not in any way arguing that oil analysis is not a good tool to extend service intervals. I just don’t see the point in extending the interval on an in warranty engine that only holds 10 quarts of oil. A new engine alone (not including labor) is going to cost you 6-8k dollars if it fails...

    2018 Chevy Duramax Fuel Injector Failure

    The number 4 injector on the L5P is one I keep seeing failures reported for. Often times it is just a bad connector and not the injector itself (bad injectors can and do happen occasionally).If it happens again, definitely have a look at the connector.

    PSF vs ATF

    I put a new PS pump in a 2004 GMC 2500HD in April of this year after the shaft broke off inside the PS pump. I also dropped the trans pan and changed the ATF and filter while it was on the lift. I used Delo Syn ATF HD ( TES-295 clone) in both the PS/hydroboost system and the transmission. No...

    2018 Chevy Duramax L5P - 6,400 miles 37,800 miles total - Oil not changed

    What‘s your OLM percentage? I’d be changing it by the OLM until your warranty runs out, no matter what the oil analysis says. These have a 5 year/100k mile powertrain warranty.

    2019 Tundra ATF.... Burned?

    We’ve put about 10k miles on a 2016 4Runner with a single drain and fill with Maxlife at 22k (~32k miles currently on the car). Shift feel is the same as with 100% factory fill WS in trans. I’m planning another drain and fill with Maxlife on the 4Runner at the next oil change. I also used to...

    Dex VI in Prius

    He’s had Dex VI in his Prius for 210,000 miles, being changed every 60k miles. He’s had Dex VI in his Prius for 7-8 years. Either is isn’t harming anything or the damage is already done. Either way, the vehicle is close to 250k miles, which is a respectable service life out of any vehicle...

    Lubegard in a GM transfer case?

    All the time, this truck does a lot of heavy hauling with a gooseneck and sees some off-road use while towing, so I do tow quite a bit while in 4x4. Like I said before, I think Dex VI is doing just fine and I don’t think my transfer case is dying or anything. I’m just wanting to experiment a bit...

    Lubegard in a GM transfer case?

    A family member has a low mileage 05 Trailblazer with a 4L60e. I dropped the pan and changed the filter and did a cooler line flush with Maxlife. The transmission was shifting fine before the fluid change and slightly better after. It has always shifted a little slow in my opinion, it almost...

    Would you run these oils in a 6.7 cummins?

    Do you have to do stationary/service regens on them? How often do they regen? My L5P Duramax will do a regen roughly every 8-10 engine hours regardless of miles. Sometimes I go 60 miles between regens and sometimes I go 600+, depending on what I’m doing with it. I am also curious to hear the...
