Was in autozone today, overheard something I didnt know before. A guy was buying 10w-40 oil for his car, the clerk told him not to get it. According to him, it's obsolete, fair enough. But the reason it's obsolete? Because although 10w-30 and 10w-40 weigh the same, 10w-40 requires the engine be hotter for the oil to "run". Apparently a lot of engines were overheating because people were running 10w-40 (he said this, not me) and the engine had to run hotter for it to work.
Also while in the checkout line, my dad asked him about spark plugs for his outback, how the manual recommended not using platinum. Clerk said "yea german cars are weird like that", he told the clerk subaru was japanese, and he responded "oh they're japanese now?".
