91 octane
91 octane or better. Its on a sticker on fuel filler door.
You need to put some heat in your gas tank; sounds like you have water passing through the fuel injecters dirt in the intake manifold/throttle/air flow meter
their really is not a specific fuel octane mix. if you just run premium in it, it will be fine, but if you do put octane in, just put a little bit in it. because it could make your fuel too rich and foul out your spark plugs.
depends on the wrong fuel you put in it. There are a lot of different fuels. In general, if you put the wrong fuel in the engine, if its a higher octane it will over rev and blow up. If its a lower octane, it will puddle and flood the system.
what do you mean wrong fuel did you put diesel or 89 or 93 octane in it when it runs on 87
Depends on the SUV. Most were not intended for it.
Simple, If you engine requires 91 octane, and you put 87 in it, you will experience a degradation of engine performance, due to the lower octane having faster burn properties. If your engine requires 87 octane and you put high octane (90-91 octane) fuel into it, you will NOT see a performance boost, and may even see a slight decline in performance. What 99% of all people don't know is that High Octane fuel actually burns more slowly, than lower octane fuel. This property, allows higher compression prior to detonation, hence more performance at combustion.
They are additives that you put in your gas tank when it is full to clean your fuel system or improve the octane rating of the fuel.
regular octane 87 will do fine u can put higher octane if u wish
Try running it on 87 octane. If you detect pinging move up to 89 octane. If it still pings you will have to go to 91 octane.
It runs. High octane is what is required by high compression engines in order to prevent pinging. Unless you put the hi octane fuel in the oil filler. Then it will only briefly run before it explodes.
No. 91 octane is the minimum. I notice a huge difference in the way a Cadillac runs on 87. I always put 93 octane in Cadillac Fuel systems.
