Piston Slap: Knockin' on Stoichiometry's Door?

Hi Sajeev,

I have a Piston Slap question: Most of the gasoline sold here in New Mexico is high altitude gas, meaning that Regular is 86 octane, Midgrade is 88, and Premium is 91. The owner’s manuals for my ’06 Corolla and my wife’s ’08 Hyundai Tucson (try not to be jealous :-) ), calls for 87 octane fuel. Am I OK to use Regular or should I take the manuals at face value and pay a dime more per gallon for Plus?

  • 28-Cars-Later Ford reported it lost $132,000 for each of its 10,000 electric vehicles sold in the first quarter of 2024, according to CNN. The sales were down 20 percent from the first quarter of 2023 and would “drag down earnings for the company overall.”The losses include “hundreds of millions being spent on research and development of the next generation of EVs for Ford. Those investments are years away from paying off.” [if they ever are recouped, emphasis mine] Ford is the only major carmaker breaking out EV numbers by themselves. But other marques likely suffer similar losses. https://www.zerohedge.com/political/fords-120000-loss-vehicle-shows-california-ev-goals-are-impossible Given these facts, how did Tesla ever produce anything in volume let alone profit?
