My owners manual tells me to use regular grade gas which I think is 87 octane. Any benefits to use a higher octane gas? Will the higher octane burn hotter or cooler and what is better for the engine?
The key words here are CAN PRODUCE. If you have a stock sled that is designed to run on 87 octane you will NOT gain power by using 92 octane. That's the reason race sleds use advanced timing and increased compression. Race fuel runs cooler so you can run higher compression and still be safe. If you do run 92 octane in your firecat you will probably not notice a difference in power. If you run 110 race fuel you probably will notice a DECREASE IN POWER. It will also be tough to start cold. Horsepower = heat and if you run cooler fuel you lose heat. So the answer is no you will not gain power by increasing octane unless you do the proper mods. You may gain some safety, but do you really the factory has the motors tuned so the recommended octane isn't safe???the cooler ur engine is the more power it can produce[/b]
