    Tesla just laid off entire new vehicle team and supercharging team

    I will agree with you on this. Not a single poster. Including yourself. All we can do is speculate but only Elon knows the plan. As the company founder, largest shareholder and CEO, he can do what he wants with it, as it should be. He has many options with the charging network. Sell it, spin...

    Auto-Braking required in 2029

    - - = + ... Thanks for confirming my statement makes perfect sense. Of course it does.

    Auto-Braking required in 2029

    This rule is dumb and will cost more lives than it will save. There are times when you need to "push through" an obstacle. Like when you find yourself on a railroad crossing and the bars drop. Or through an angry mob. Or through a snowbank. The list is endless. Also, these systems are...

    Walmart M1 5w-40 Euro pack of 3 for $24.47 Seems to be working again.

    Fedex delivered all 6 jugs just now! Awesome deal. Shipment originated in FL (to TX) so more likely it was a price mistake rather than regional clearance. Happy! Thanks OP!

    Walmart M1 5w-40 Euro pack of 3 for $24.47 Seems to be working again.

    Ordered two 3-packs of 5W-40 for shipping, delivery on Sun. Let's see if I receive 6 jugs or only 2.

    Valvoline Advanced Full Synthetic 0w-20 5 quart jug @Walmart online $11.49

    Still available but too thin for me. Thanks for posting!

    Walmart DeIcer washer fluid 1.50 /gallon

    Good find. In Texas, Walmart doesn't seem to carry Peak Asian nor the SuperTech de-icer. :(

    Oil is Oil

    Yes. Just like "car is car" but clearly some cars outperform others. In programming terms, all instances of "Oil" belong to the same class, however, they have different properties. class Oil { constructor(baseoil, additives) { this.baseoil = baseoil; this.additives = additives; } }

    Tribologist discusses 0W8 motor oil

    My primary concern is camshaft lubrication. PF's lubricity test is a close as it gets to simulating cam lobe on slipper pad action. I don't pay any attention to the cold oil race, etc. These photos of an intake camshaft and rocker arm from one of my cars. The result of using 5W-30 "energy...

    Tribologist discusses 0W8 motor oil

    1st prize for the most pathetic post here. No arguments, only personal insults. Instant ignore.

    Tribologist discusses 0W8 motor oil

    PF's lubricity test setup is clearly far more rudimentary compared to the tech that LSJr has at his disposal and I do take the results with a grain of salt. That said, it does provide a set of data points that I view as valid. The results are consistent with more advanced lubricity tests. There...

    Tribologist discusses 0W8 motor oil

    Thanks for the link. Interesting stuff, especially under References. So the rare, expensive, unobtanium additives are Ionic Liquids. If I understand correctly, these are basically salts in liquid state which supposedly have friction/wear reducing properties but their chemical stability is still...

    Tribologist discusses 0W8 motor oil

    So according to the chart he shows, 0W-8 requires a large dose of super-rare, expensive, unobtanium additives to perform on par with an off-the-shelf 5W-30. I will watch the follow-up UOA reports with interest. He seems to be well aware that the only reason Toyota is pushing 0W-8 and long oil...

    Moly or Boron preference?

    I prefer ZDDP around 1500 PPM. I pay no attention to B/Mo levels. Many lubricity tests show that high(er) levels of ZDDP lead to great reduction in wear. In this lubricity test, two Castrol oils of the same viscosity were tested for wear. The oils were identical in composition, only the levels...

    Does Pennzoil have a racing/high ZDDP oil?

    I asked thIs question in the Pennzoil Q&A thread and the answer directly from Pennzoil was NO. Also, the Pennzoil API oils tend to have the lowest amount of anti-wear additives like ZDDP of all the brands. Many VOA tests of PP 5W30 repeatedly show Zn levels around 540ppm, which is below the...
