Now I know why I didn't get much sleep last night.

No, you nailed it.

I'm lucky I have a Shell non-ethanol station near the house. Is Shell's 93 Premium you guys' choice?

And: do you have any problems finding non-ethanol gas where you live? I have no problem here, but it's frustrating trying to find non-eth in other places like the DFW metro, for example.

Don't get me started w/ that Ethanol crap, it's almost 100% where I live and the highest octane I can get is 91 at Sams club which didn't use Ethanol until last year and at least doesn't carry it year round (yet). Whatever % of Ethanol is added is the % decrease you'll get in gas mileage, what a bunch of snake-oil that junk is.

Most delusions need validation, and for some people attention = validation, so they proudly declare Teh Crazy in public. Getting laughed at doesn't really matter, because attention is good, regardless.

They're kind of like trolls, except that actual trolls are motivated to p1ss people off for the fun of it. (Because Psychotic.) Either way, the end result is the same: people get p1ssed off when stupid people say stupid things under the delusion of being vastly smarter than everyone else.

Ever hear of the Dunning-Kruger Effect? There's quite an ah-ha moment when you see it.

I am, however, concerned with how I'm going to regain the brain cells I lost by reading this thread.

This is an urban legend. Ignore these people and let them pay 30 cents a gallon more for Chevron gas (use the Costco Amex and save 2% more).

I've been using Costco gas years and have put 100K+ miles on more cars than I can remember with 0 issues.

3.10 is high? I just paid 3.60 for gas in CA, and its ethanol blend with 91 octane..

Theres a race gas station around where I live that sells 87 all the way up to 100. The 100 is over 6.00 a gallon!

JinV36

alright. Cause Im using Amex and as low as 2% is, I am thankful for that haha. People say the chevron is the "only" real premium gas but I always liked Costco. I also like how it's classified for members only, in a way.

But yeah Costco gas is always ~10-30 cents cheaper than most gas stations for me, especially chevron

I'm now convinced that Telcoman primarily posts to get a rise out of our otherwise peaceful, helpful community . And, he succeeds.

Soooooo... I'm running 89 Octane... Am I making a mistake? I've only had this car for 2 weeks and trust me, I've been through the "search" and other posts... Nothing CLEARLY states whether I'm screwing myself or not...

Flakman

As stated previously. Premium is not a recommendation by Infiniti, it is a requirement. The cost differential per tank is about $4 to $5. Yes, maybe you could run 89 and not have issues, but that's a risk you will have to calculate for yourself. If you drive spirited, you'll likely see/feel the difference sooner and more often with predetonation and pinging. I personally do not know as I will put nothing but premium in the tank unless absolutely necessary. For me, though I bought used, I paid more than I have paid for a vehicle in a long time. I'm not going to jeopardize the best car I've owned for $5 per tank of gas.

paulmnly

Very true... So If I make the switch now to 91... You think it would be ok? I understand the whole "predetonation" issue and don't even want to deal with it...

Flakman

I don't think you should suffer long term issues over a short time like that. This is what I have gathered. Long term predetonation/pinging can cause excessive heat and wear as well as issues with plugs and valves which is what the higher octane gas is required to prevent. It helps with performance, but only with regards to reducing the pinging which will reduce performance. The ECU may do what it can to compensate for the pinging by messing with timing etc, which is not what you want either. The higher octane doesn't burn faster or more efficiently, so the gas itself does nothing for performance. The increase in octane is specifically to prevent the pinging.

Hope that helps. It helped me understand better for sure.

I'm totally with you on that one. Couldn't have said it better. I guess Baltimoreans think a like.

I say burn it if you got it Now I just got to get some Torco 110 octane. Actually that would probably be a waste since our motors aren't set up for it and the higher detonation could cause overheating.
