You are in fact THE ignorant moron here !
You talk out your ass because you don't really know sh*t !
What, do you drive your moms car ??!!

Do you even know how to read ?!
The question was "Will it damage your engine"
The fu**ing answer is NO.
Modern engines adjust the timing to compensate for different octane gasolines.
Get your head out of your A*S !!

"One knock damages an engine" ??!!
You are an idiot.

Good article and good information !
Unfortunately this forum is swarming with idiots who can't even read or think rationally.
Everything they know has been gleaned off the internet.
I doubt that 95% of the members here have ever even picked up a book or know anything about being a true car mechanic, which I am.
Ignorant Fools !!

Why so aggressive? This is what the owners manual says "Use of a gasoline with a pump octane less than 87 can lead to engine damage." So the answer may as well be YES.
