    279,000 miles - Mitsubishi Mirage engine teardown - top end vs pistons

    An engine that small isn't exactly loafing when it powers a car at a sustained 70+ mph, especially if there are hills involved.

    My 75k OE air filter

    Same here. My air filter looked cleaner than that when I last peeked, which was at about the same mileage.

    Synthetic oil question about length of time not miles

    There's little reason to count the years, as long as you aren't making any short trips between the long ones.

    Why/ why not run oil level at MIN?

    The title question would be a perfectly reasonable question if slightly rephrased as "Why not run oil level near the MIN mark." That is unlikely to do any damage IF the user is careful not to let the level fall below that level and isn't taking turns near the limit.

    Unique Mahle filter construction

    Sometimes the "gasket holding piece" appears to be spot-welded on.

    Free oil change on Dealer !! good or bad ??

    It varies. Some dealers will use appropriate oil, but others will cut corners. When I went for one of my "free" oil changes, I asked the dealer what oil they use. She said it is bulk Toyota 0W-20 made by Exxon, which was true as best I can tell. It shows up on the receipt as a Toyota part...

    Oil age doesn't seem to matter

    FYI, live trees generally stand, not sit.

    Oil age doesn't seem to matter

    Yes, total time in the engine is irrelevant, but time spent running under adverse conditions (cold, very hot, or contaminated) is not. Manufacturers list maximum allowable time as a simplified way to cover frequent short trippers. Oil is going to be in worse shape in the engine that is used...

    Here's a trick for pre filling filters

    The dry start "every X thousand miles" is a little more worrisome than the "one every start" (with leaky anti-drainback valve) because in the latter case there's still some oil in the filter, absorbed by the media, and below the lowest inlet opening (assuming a spin-on filter in horizontal-axis...

    Hengst oil filter inflow holes changed, should I use this new filter??

    In other words, it's irrelevant---although much-discussed.

    Here's a trick for pre filling filters

    It's very odd and inconsistent that conventional BitOG wisdom holds that pre-filling a completely dry new filter is pointless, yet at the same time a fully functional anti-drainback valve is essential to prevent some of the oil from draining out of the filter between starts.

    Those with 150,000 miles or more, check in

    Ok, I'm "checking in" now because the odometer of my Prius passed 150,000 indicated miles today. The engine shows no apparent degradation of any kind since I got the car ~109k ago. 150k is not high mileage.

    10k on Fram Orange

    It looks to me similar in construction to the US-made version of Extra Guard 10358 (smaller cartridge for smaller Toyotas)---which is remarkably similar to the Walmart version. Besides the US version and the Argentina version, there's also a China version of the Extra Guard 10358. Only the...
