Murphy USA 93-octane here now that I've moved. Only Murphy and Sam's Club sell 93 E10 here, everyone else is 91 E0.

Only this for my Z.

3 gallons of E85 on empty along with a full tank of 93 based on my best friend in the ethanol businASS

How has the Sunoco 94 performed for you? I tried running it on a few occasions in my Corvettes and they always idled & ran a bit rough.

 

[jacksonmagnet]

No issues like that, don’t seem to notice a performance difference between them, just feel better about the 94, I got e0 94 once and that seemed maybe a little smoother, might just be in my head

Sinclair 93 is the only thing I put in the Z.

I wish the Sinclair's here had 93! Only 91...

I only mess with Shell 93 but then I put a small amount of ethanol in it to boost it to e15-20 since I run a TruControl.

How much E85?

Wait, weren't you the one just complaining that the Trucontrol sucks on another thread?

I will likely run 93 octane from Shell, but I can also get 94 from Petro Canada (Sunoco), if 94 is in the same price range as Shell's 93 I could use it as I get a discount at PC.

My dealer told me that we can use 87 octane without an issue, I don't have my owner manual yet as I get my car in 2 days, but upon further reading I think they are screwing with me. Dealers and sales people can be a problem quite often. My car is at the dealership (outdoors), on Friday I went to see the car and I told them to lock it up before the end of the day (like I really need to tell them that right ? ) . They said yeah no problem it will be locked and taken indoors over the long weekend. I went to dealership yesterday to show the car to my family members and it was outside, but it was also unlocked. I had to lock it up myself. Screwballs ! Good thing there was no homeless person sleeping in the car

Your dealer flat out lied to you. The Z is 91+ per the owner's manual. Putting 87 in would be just asking for reliability/durability problems.
