93 Octane
Hi guys. What reliable site are you currently using to find stations with 93? My GTR is tuned for 93. Thanks

Is 93 really not available in Cali? I think I haven't come across a single non-shady gas station that has not had 93 in PA

No 93 in California. It’s almost worth the drive to Vegas to get 105 at a few stations. It’s all for the imagined effect as our cars aren’t mapped out that far. If they were I font know if I’d spend the ten bucks a gallon often.

Cali only has 91. Non leaded race gas is still available I think....but it's expensive. Over 100 octane if I remember correctly. I don't know about octane boosters...if they are still available or effective.

I had the same experience when I went to Canada. Indeed, the idle is a bit strange with 91. Some guy knew it and bought a crate of octane booster.

My GTR is stock, and my supply of 93 octane is limited in our area. But it runs like an absolute champ on Top Tier 91 octane pump fuel. One reason I'd never get a 93 octane tune tbh as I hate 'octane boosters'.

Fantastic stable btw!!!

I always use 93 octane plus a half can of boostane in all my vehicles. No problems after 10 plus years don't be afraid of the fake news about torco or boostane.

Now this begs the question. If my car is tuned for 93 and I use 91 (since 93 is not readily available here), what happens?

Well I wouldn’t do too many WOT runs on a hot day. Not without increasing the octane somehow. lol

That being said hopefully the tune has in-built tables for lower octane tune and can adapt like the OEM ECU.

Might be a good question to ask of the company who tuned the car though.
