I always used 90 octane which was more like 87 or 89 untill the prices rose so I filler my 94 HO auto with 92 octane this is what I noticed:
1- smelled different
2- Higher mpg
3- Better performane
4- (this is the strange one) it Wont start as easy as before when the car is cold it doesnt start from the 1st time unless I keep cranking for 10 sec.
I tried to turn the key twice so I can force more fuel from the fuel pump but still.
Is the higher octane level detonates later than the lower one so it needs more compression to start the engine or I need to change my wires , spark plugs.
ps: just changed my battery with a Varta 65 Amp instead of my usual 55 Amp ( installed it the day before I filled her with 92 )
