  1. Are we in denial about the factory oil viscosity and grade specifications?

    Letting people make their own decisions is always dangerous --It's called liberty. This thread doesn't need the thought police accusing consenting adults of committing thought crimes. You and everyone else on this forum are at liberty to make the decisions you believe represent your best...

  2. Are we in denial about the factory oil viscosity and grade specifications?

    More good data. Thanks for being brave enough to say it out loud. --some folks get truly butt-hurt if you dare think independently and question the status quo. OBEY! Pretty sure the specs for bearing clearances on the early Pentastar rotating assemblies are the same as current versions...

  3. Are we in denial about the factory oil viscosity and grade specifications?

    I wouldn't. You are clearly not an edge case for your particular engine's follower/arm issues either, and you keep up with your maintenance. The VVL issue is more curious though and more closely similar to the higher pressure flat-tappet cam failures. If a better formulated oil, even if a...

  4. Which 37" tires are closest to an actual 37" inches in real life?

    TyreRawck lists the tire specs in a back-page tab. At least for Firestone and Cooper tires, if the spec says actual tire size is 33.2" and 601 revolutions/mile, it's been pretty close to accurate IME.

  5. Are we in denial about the factory oil viscosity and grade specifications?

    Awesome. One more data point, and confirmation 40 weight didn't cause phaser or VL issues on yours. Thank you.

  6. Building my own flush tail lights

    Very nice. Way to do something actually productive and then post it. Hat tip. I get Rivian vibes --neither good or bad from my perspective, just noteworthy. Maybe as a result of the forum ads.

  7. Are we in denial about the factory oil viscosity and grade specifications?

    Thank you, Flyboy2109 for offering your first hand experience. ZDDP is a great anti-wear additive from what I understand. You didn't recommend everyone shot load their oil with a 90% concentration of it, so I'll assume you trust that clever folks reading the forum can do some research and...

  8. Are we in denial about the factory oil viscosity and grade specifications?

    Yes, good eye. It peaked mine as well. My first OC will probably be this Rotella or a euro-spec 0w40. Maybe I'll even go for my bawls and commit with Rotella 5w40. We'll see how I feel at the time.

  9. Are we in denial about the factory oil viscosity and grade specifications?

    Corporate Average Fuel Economy. AKA Draconian government legislation that forces automakers to build trashier, less durable, and more dangerous automobiles, for the purpose of improving fuel economy/reducing emissions. I and all my family have also used HD diesel oil in all our gas autos...

  10. Are we in denial about the factory oil viscosity and grade specifications?

    The cam and interface damage appears to be a textbook example of insufficient oil film strength. Between the reduction in viscosity and the reduction in friction modifiers in modern xW20 and xW30 oils, are we simply refusing to accept that Jeep has sacrificed longevity for CAFE and questionable...

  11. Stellantis CEO: Earth Doesn't Have Enough Raw Material to Meet EV Demand

    Maybe an eye opening thought experiment for anyone interested —go to the EIAdotGov and convert the annual US gasoline consumption into kW. Then from the same official guberment site, compare that number to the US’s total electrical grid production. Layman’s math: US grid production, from any...
