[s-cars] Gas Prices

[Bruce Mendel]

That's pretty much true, except:

1. Some pinging is not audible.....and the ECU might be cutting back on
timing and boost prior to your being able to hear it

2. Detonation on a high-boost, high-revving engine can be more damaging than
on an NA big block, so better safe than sorry.

I've been told by a veteran (25+ years) auto mechanic that the only
reason any would ever need/use higher octane fuel, other than for racing
purposes, is to reduce or prevent pinging.

In other words, if your car doesn't ping don't waste your money on
higher octane for normal driving purposes.

I suspect I'll be receiving rebuttals to this.

In Europe they say "recommended : 98 RON", "95 RON is possible but with
lower performance and worse gas mileage"...

98 RON is about 93 R+M/2
