I've always been a Shell premium guy and have never had any issues. Some things I always do though. Never buy gas when they are refilling the tanks at the station, never get below a 1/4 tank, and I always buy from newer gas stations as their tanks are usually newer and less prone to corrosion.Any specific gas recommendations for the FL5? Finding 91 octane is challenging around me and I’m no fan of 10% (or greater) ethanol. Also seems that some less expensive types tend to knock even if rated as high octane.
Should I pick up 93 if it is available near me? Keep in mind my elevation is around 6500ft so I think 91 is basically 93 at that point.93 only if available near
stay away from discounted gas stations such as 7-11, race trac, Sams, wawa
stick to top tier stations with additives like shell, Mobil, chevron, Sunoco, Costco
Sounds more psychological than anything. I doubt that refilling under any of those conditions would have any noticeable effect.I've always been a Shell premium guy and have never had any issues.

Prob not in these modern times as I was taught this by a legendary Porsche sports car team boss a long time ago. It's just something I've always done. I usually fill up at the same Shell station anyways though.Sounds more psychological than anything. I doubt that refilling under any of those conditions would have any noticeable effect.
It’s been proven the engine knocks on 91 octane. Adding ethanol reduces this. The knock is probably not enough to cause long term damage but it’s still engine knock.Get the best octane you can get 91, 92, or 93, and I prefer non-ethanol as you will get best fuel economy from it. Ethanol fuels result in less fuel economy, as small as it may be.
I agree with this.It’s been proven the engine knocks on 91 octane. Adding ethanol reduces this. The knock is probably not enough to cause long term damage but it’s still engine knock.
actually perform better, so who really cares about the 10 extra miles per tank?Get the best octane you can get 91, 92, or 93, and I prefer non-ethanol as you will get best fuel economy from it. Ethanol fuels result in less fuel economy, as small as it may be.
So 92 octane fuel using ethanol performs better than 92 octane fuel without ethanol ? Octane rating denotes the resistance to knock, so a 92 with ethanol is the same as 92 without ethanol. Same applies to any octane but I just used 92 in this example.actually perform better, so who really cares about the 10 extra miles per tank?
