Does anyone know what octane is required in the 1000? I looked around and cannot find it anywhere....Cheers!

I imagine it was designed to run at all octane levels, however, any performance mods can change that very quick. If it were me, I would likely run 91 all the time.

I was trying to see if I could get a definitive answer for you, however, no luck yet.

If the Commander is rated for 87 octane, anything more will not make a difference. You see, on EFI machines the fuel map is set in the ECU and will not recognize or benefit from using a higher octane. Now if you get a programmer you can set a new octane rating and that will give you a couple of extra ponies. People do the same thing with cars all the time. The car is rated for 87 but they buy 91, and their wasting their money. Some think they will do it anyway because they think it is a cleaner fuel, and that's not true either. Now if your engine is rated for 91 and you use a lower rated fuel, that is definitely bad for an engine and you will get a ping. You guys can google it too, there's a ton of info on it. I don't know what the Commander's rating will be but I know the Outlander is rated for 87, which makes me think the Commander will be too.

This does not answer the actual question, however, it does give some insight in regards to octane ratings.

The Ciommander requires regular gas. Higher octane is typically designed for higher compression motors and actually burns cooler than than regular 87. You do not gain anything by using higher octane than a motor is designed to run on. In a lot of cases you actually lose HP.
