FWIW, all gas has sufficient detergent to keep injectors clean now. Premium has more octane, that's it. If you don't know what octane is, look it up, don't rely on the misinformed folks here.

And anyone that posts (other then you, of course) is "misinformed", I take it?

Oh is that right? Any links or articles supporting this claim?

And he's the one who posted that taking your car to anyone other than Infiniti for service will void your warranty, yet claims to use a 10K mile OCI which is outside the recommended schedule.

i heard if u use higher octane like 100 or something, ur car will go faster n louder. is that true?

The VOIDED post was sarcastic, my friend.

There is no such thing as metric octane. There are two ways to measure octane, the research and motor methods. The results are reported as RON and MON. The RON will be about 10 numbers higher than the MON for most gasolines. The US and Canada pump octane is reported as the average of RON and MON, seen as R+M/2 and also called AKI (anti-knock index). The rest of the world uses just RON. Therefore you can subtract 5 from octanes elsewhere to get the US equivalent, it's not exact, but close enough. Hence 98 in Europe or Dubai is 93 here.

Nope, for some reason, I can't find an article related to the octane measurement and the middle east. I come from the point that only the US and Canada use the different measuring system.
I have tried 100 octane in London (95US octane), however, it costs twice the regular and it is not for mass sale.

There should be a sign at the pump explaining the octane measure though.

Good Threat. Will revert back to premium gas. My car has 5k miles now, and I thought what if I tried the super-unleaded (rating 89) at Shell. Although I feel no kocking at all, I do feel the car is slightly less power, but it's ok to me. The only I worry about is, I go against Infiniti's suggestion of 91+, so I'm afraid for the long run, it may damage/rduce life of the engine. That's why I went to this forum to see what other ppl are saying. It now makes sense, that I should really not be cheaper about 10cent a gallon and go all the way to premium gas, as I have been since day-1. I probably never want to put regular unlead (87) in my tank. It's too far from recommended 91+.

Oh well, too bad, I'll have to stick to a 30cent different between 87 and 93 octane gas...for the rest of my owning G37. But I think, it's probably the right thing to do.

Thanks.

you're lucky if you save maybe $2-300/yr trying to be cheap on gas. not worth it at all.

in my car i only fill up 91 and 91 only never touched another type of gas... im wondering if i put octane boosters from 91 to like 93( each bottle is like 2i think) whats the max octane are can handle any feed back?

This is the best explanation of the differences in gasolines and what to do to keep your engine clean that I have found.
