    I couldn't imagine running a motor oil for 20k miles in these things. Given the tight clearances and 3 qt sump that oil would shear down to an unacceptably low viscosity. I would need to see repeated used oil analysis to change my mind.

I want to do compression on it one of these days. It is a bit clacky when warm and occasionally uses 1/2 qt between changes. It's at 494k km(307k miles) right meow.

    I change my oil twice a year in the turdmobile and ol' lady's dumpstermobile. The truck gets an oil change every other year or so? It's slightly overdue...
    That's what I do too, every 12k km. I just feel like these basic ass engines can take a beating.

    Thanks for sharing all that! Sounds like Mobil 1 is working out well for you.

    I'd walk up and say "You did change my mind, now I'm offended."

    My mantra is, "I try my hardest to not be offensive and even harder to not be offended."

    I feel like if I was political and Canadian, I'd be considered conservative, but in the states, I'm considered liberal.

    All I know is, I'm very much politically erect.

    Well, that doesn't sound unreasonable to me. I just drained my oil at a 7,500 mile interval, and same as above. The oil level was still at the top. The oil didn't look "clean" like new oil, but it looked like it was carrying a very manageable amount of suspended particles and looked quite healthy. A 7,500 mile oci on mostly suburban driving doesn't concern me the least. It's probably overkill, but I'll stick to the manufacturer's recommendation.

    So, with some explanation from minibishi2, I think he seems to be aware of what he's doing, and I doubt he's doing any engine killing harm. More power to him!

    However mb2, Fummins knows his stuff. I'm betting his reply is based on various others that have posted same or similar things as you, but didn't follow up or explain their rationale. He B OK.
