You need to use premium fuel, the fuel u are using can cause predetonation, and cause knock. Which will ruin your engine
It could be that you are not using high enough octane gas in it?
You are only supposed to use 87 octane fuel in the ZX2 escorts according to the owners manual. I haven't noticed a difference if you use a higher octane rating
If you mean "leaded" gas (it it's even available), then the answer is no. It will damage the catalytic converter. Infiniti recommends and octane rating of at least 91. An octane rating of 87 can be used temporarily, as long as you don't accelerate abruptly and only fill the tank partially full.
Sounds like the heat shield on the catalytic convertor or the muffler has broken free on one of the mounts and is rattling from the increase in R.P.M.'s.Dont rule out Knocking. try some higher octane fuel or some octane boost.
absolutely....you can mix any octane with any other octane
There is no octane in gasoline... it is the equivalent of octane.
NOS octane booster
Yes, the higher the compression ratio, the more octane the fuel has to be. Anything over 10.0:1 has to be 91 or higher. However, if performance is not an issue, than you can use any type of fuel you want, but car will not accelerate fast and its torque curve will be very bad. Using low octane fuel in a high compression engine will also cause knocking (pinging, pinking). This will cause damage if continued.
It has no octane rating.
Octane is a hydrocarbon.
Octane has not special application excepting the so-called octane number.
65% of 87 and 35% 93 to make 89 octane gas
