The mother of all 2IS gas discussions. Premium or Mid-grade (merged threads)
This is the mother of all 2IS gas discussions.
Please post your "should I use only premium or can I use mid-grade or regular gas" questions here if you can't find the answers and opinions you seek from the posts already here.
I've merged several discussion threads on this exact topic together here & will add this to the FAQ.
Keep in mind some of the earlier posts are from just before the 2IS was formally released and specs known (such as compression, etc)

What Type Gas Expected for IS350
Since this will be a V6 engine, do you think it will take regular or premuim gas. Man, gas prices are still way up there & it's killing me.
I know my Lexus V8 baby uses only premuim gas. Since the new IS350 will have over 300 hp do you expect it to take premium?

I think Lexus will definitely RECOMMEND 91 or higher octane. However, I do think running 87 will be possible but with degraded perfomance. It would be silly if people get stranded in some remote area just because premium fuel is not available . Just my two cents.

Yes, no doubt. As with most cars since the early 90s it will probably have knock sensors to retard timing when using lower octane gas.

most luxury brands recommend Premium (91 Octane). As some have said, with both engines using such high compression ratios, premium probably should be used. It's a pet peeve of mine when people don't put the recommended/required fuel in their car. I know a 1998 Audi A4 1.8T owner who puts 87 Octane in his car when 91 is pretty much the needed octane (it's a Turbo, I don't understand his logic!) Off Topic, but I figured I'd share.
