Is anybody clutching their chest on this one? I've got 600+ hours now, all on COSTCO av fuel with no issue. I fly 2x week minimum and just put new hoses on. I did not see anything new to worry about but am curious if anyone is changing their fuel regime.

Does anyone knows of non-ethanol 93 octane fuel located south side of Houston Texas?
Bucee’s used to have it however they lowered their octane to 87.

Pure-Gas.org purports to show some stations in south Houston.

If you have a 912UL you can use 87 octane or higher and if you have a 912ULS use 91 octane or higher.

Good luck

For what it's worth: someone told me some years ago that after further investigation only BP puts very little ethanol in it's gasoline - I buy BP 98 for my bird since then (Europe, ULS engine)

You can buy inexpensive ($10USD) test kit to determine % alcohol in auto fuel...

I use Costco premium exclusively except when on trips. Every 6 gallon jug is tested for alcohol content, it always runs between 6-8%. On trips if I can find auto gas close to the airport I always test it before pouring it in. The plane during my ownership has flown 725 hours in the past 35 months, a little north of 3000 gallons. I am based in SoCal with typically very HOT summers. Only once I suspected a situation similar to vapor lock and can't be positive. I always purge the fuel system with the electric pump before starting. I believe that is very important to pushing the heat soaked fuel out and keeping cooler fuel in the lines to the carburetors.

I have my Dynon set to alarm me if the fuel flow drops below 1.8 GPM. If I was to get this alarm it would mean a potential vapor lock situation. In testing (on the ground) at full power and turning the fuel valve off the engine will run for 15 - 20 seconds. In theory if I got the low fuel flow alarm I would have 15+ seconds to make a plan for landing, that's a lot of time in an emergency.
