    Aftermarket Air Mass Meters

    Why do you think your new aftermarket MAF sensor is not working? Any discussion of MAF sensors or engine closed loop control in general needs to start with MAF sensor reading at idle and LTFT under a constant load - like driving 30mph down a long street. If you can log MAF volume x LTFT x rpm...

    "Fuel Efficiency Standards Are Dead"

    You need to be a little bit careful on this calculation, simply because its in USD's so its calculating the changes in currency as well as the change in GDP. A house in Germany doesn't go up 20% in euro simply because the Euro is down 20% in dollar terms from a year ago. However some things...

    Oil changing questions I should have known by now but don't

    1) If your not having to top off between changes I would not worry about oil consumption. I more or less know by how much comes out. On my Nissan's 5.5 quarts go in, more then 5 quarts come out. Close enough. If you have an oil burner keep track of how much you top up between changes. 2)...

    All these other coins make no sense to me. At least Bitcoin has some transparency and is scarce. When you can make a meme coin out of thin air your really just trading Tulip bulbs that won't grow. IMHO. But again, what do I know. How about Fartcoin? Yes its a real coin - before you all hit...

    Supertech filters discontinued?

    Auto OEM's don't make filters. Motocraft are M&H or were. Champion used to make the AC Delco. Maybe someone here knows if still? Mopar is also M&H - or used to be. If you believe somehow they pay closer attention to the OEM ones I suppose. Up to you. I'll pass.

    Relic from the lubrication industry

    ESSO is 1972 at latest. Very cool.

    Supertech filters discontinued?

    I agree completely and bought WIX North Carolina made filters exclusively for decades. Unfortunately the USA made ones no longer seem to meet any minimum standards of quality control, yet the Chinese and Vietnamese made ones are impeccable. 🤷‍♂️ If you want USA made I think many have gone to...

    AN 124 escape from Kyiv

    Good. If you haven't seen the footage of the drone attacks deep in Russia, its worth a watch. Just search "ukraine drone attack on russian planes" or anything like that and lots of videos will pop up. Given they destroyed the Antonov AN-225 - the largest plane ever flown, I call it karma...

    Supertech filters discontinued?

    Pretty much I think. The MP's went away a year ago - equivalent to the Champ XL. A couple showed up here with manufacturing defects anyway so no loss really - I did use them back in the day. I have one left I will likely toss. Move on to some variant of Premium Guard. All things First...

    Toyota ... warped rotors

    I have owned exactly 1 Toyota. Its in my signature - 6 years, only 46K miles, most of it my wife's commute. The brakes are still silky smooth. Maybe its all that driving on the shoulder during rush hour you Bostonites find acceptable. Do they still allow that?

    "Fuel Efficiency Standards Are Dead"

    the CAFE footprint formula is at least part of it. How much gas you can burn is based partially on the footprint - or the track x the wheelbase. The bigger the car - the more CAFE allowance. The safety mandates are another part. Lots of companies make small cars for off-shore markets - but...

    Not only did they have the pandemic money in 2021 / 22 - they were also very close to the peak number of retirees. Due purely to demographics - I believe 2024 will end up being the peak ever retiree's. There just aren't enough people under 65 now to ever catch up. So everything retirement -...

    I bought AMZN, GOOG and QQQ somewhere near the bottom of the second April pullback. Well it didn't seem like the bottom at the time - was already way back up. But it looks really good now. I think its people trying to get out of the dollar and into real assets - of which there are not too...

    I agree that Ford has some really good engine tech. That is why Toyota agreed to swap their hybrid research, undipsutedly the best at the time, for Ford's engine research. Unfortunately Ford is plagued by the thing that has always plagued Ford - QC and other cheeping out - like refusing to...

    Please define American car company? Toyota's largest market is USA. Same for Mazda, Subaru, and Nissan. Ditto for everyone really unless China is, which there on-shoring their Auto Industry so its not the largest market anymore. BMW is the only one I know of headquartered outside of China...

    21 RX350 and a PulseTech XC400

    Majority of your test results are at way to high of charge. Your testing with a residual. Your headlights are not taking enough off. Should be at 12.66 (full charge on 6 cells) or less. So that will inflate your health number and such. Still the battery looks good to me because the internal...

    Battery replacement estimate

    That’s probably the most reasonable “shop supplies” estimate I have ever seen - comparatively.
