is premium fuel better/worse for a regular car?

Did you know that you can save fuel and run your car on water
The Biologist questioned:
my brother has ongoing using premium fuel for his honda civic (which does not demand premium), in view of the fact that doing so, his fuel efficiency has improved by 15%, I’ve heard some say that premium fuel for a fixed engine is not excellent & vice versa, is it right?

Depends.
Engine compression dictates the octane looked-for. Too low an octane rating will yield pinging (predetonation) and eventually end an engine. Too high an octane rating is atrophied as heat in the exhaust manifolds.
Premium (91 octane) is looked-for only for normal motors, and some luxury vehicles; here must be no difference in the mpg when using a privileged octane very than the not compulsory 87 octane…why waste the superfluous $$
An engine that does not demand premium fuel gains nearly not anything by using it. If your brother is being paid better gas mileage it is in view of the fact that he is hypermiling which earnings driving for best mileage. He may not even realize he is doing it but he really wants to judge in the premium fuel thought and subconsciously accelerates more gently, anticipates reasons to coast and slow,drives slower, etc. Using premium fuel won’t hurt the car, but it will cost more per mile to handbook. Even using fixed in cars requiring premium won’t commonly harm the engine as long as it doesn’t ping or blow when using it.
The owners manual for any car gives the not compulsory octane level for the car. Running a privileged octane is only excellent to sterile the logic out once and a while. One tank each couple months is all you need to do that.
Fuel burns heating up air which in turn pushes the piston. Low feature low octane fuel and air mixture detonates it pings and knocks. The blow force not even be audible high frequency and to quick to see but a blow feeler hears that blast and retards the flash timing to limit flash blow ping. That cuts down the gas mileage. running high octane in a fixed gas motor will not hurt the motor it just force not have ample compression pressure to use all of the fuel each intake, compression, potential, exhaust logic. I skepticism that a car that got 32 miles a gallon on fixed may maybe boost as much as 15% on premium fuel. But just 2 or 3 more miles a gallon is all it takes over a 13 to 20 gallon tank to make the superfluous cost of better gasoline even out. It is best that you look at the gas filler door and consult your owners hand book before choosing what fuel you want to use. Both of my cars say “premium fuel not compulsory” on the fuel doors and in the owners manuals
in a honda civic, don’t use premium fuel. here are ZERO benefits for you. its a waste of cash. it doesn’t boost mileage, he’s probably just imagining it. only use premium in engines with high compression. if you place a turbo on your civic, then you’d need premium. additional than that, just use fixed. and yes you can use fixed if you have premium fuel in the tank if you were wondering.
