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?

Jeff "Honda said it would introduce seven new 0 Series vehicles by 2030, with the first models scheduled to reach the market in 2026." My take on this is the earliest these would be on the market is 2026 If then. I think Honda is going to drag their feet on this and 2030 is a more likely date. Honda is probably going to wait and see what the competition does before they do anything.
ToolGuy It is called a vehicle assembly plant. The parts come from all over. This part came from a supplier in Mexico, and they had a spill. There are lots of ways to mess up a part. One would think that people interested in cars would eventually pick up on this sort of thing, but I probably expect too much. Carry on.
ToolGuy Ok, the age isn't scary, the mileage isn't scary, but the badge is. But hang on, it has the bigger engine, no turbo, 'new' tires, the headlight doesn't scare me (I was wrong, slightly scary), bulbs and speakers I can do, new window regulator is under a hundred bucks, the transmission issue was scary but seems manageable (if it goes away when warm), AC issue intrigues me, headliner is easy (if what I'm thinking). I'm at $1,800 and will probably regret it but there it is.
28-Cars-Later Artistic design that resonates with people (your styling sucks Honda, so are you holding back on us?)Automated driving and advanced driver assistance systems that ensure safety and peace of mind (no one wants this)New value of EVs as a “space” for people (wouldn't any vehicle fit this definition?)The joy of driving with the feeling of oneness with the vehicle (you should already be doing this)Outstanding electric efficiency and performance (finally something relevant)
Dave M. some I think were done right were the Mini, PT Cruiser, Fiat Spyder, and 2nd gen New Beetle. The GTO, HHR, SSR, and Thunderbird were missed opportunities.
