Toyota FTS report engine issues with FR-S running 91 octane
Hey everyone this is my first thread I have started and hope I do it right ha. I work at a Toyota/Scion Dealership in Kansas and just got word from my service manager that there are reports from Toyota FTS (Field Technical Specialists) that they have documented legitimate relations between rough engine idle and running conditions with using 91 octane fuel. The owners manual does say to use 93 octane but i never figured it would be a big enough difference to cause these issues. My FR-S is due to show up in the next couple weeks so it sucks to hear this stuff ha.
When my FR-S (finally) gets here I will be using 91 octane no ethanol gas that I found using the link in this thread: http://www.ft86club.com/forums/showt...hlight=ethanol Does anybody know if 91 no ethanol is equal or in some way superior to 93 E10? |

There are some locations where it is impossible to buy anything higher than 91, like... California.

Use a little of this stuff with every fill up and you'll be good to go.

Hah I used to use the Torco stuff a long time back, it works but may eventually cause issues if you use enough of it...
The car is meant to run on 91 octane, so I imagine there will be some kind of reflash happening to fix the issue. |

Isn't that stuff like straight ethanol, which our fuel pumps don't seem to like?

I ran this stuff on my car for 6-7 years without a single issue.

That site isn't 100% , it only has previously reported gas pumps .. It shows me one shell that has ethanol free and it won't show the shell in my neighborhood ..

I run 93 with 10% ethanol and it still runs rough. Maybe 93 with no ethanal would make it much smoother.

Mine bounces ALOT between 400-800. when the AC is on it will dip so low when i clutch in that i can hear the engine chatter for a split second until it pops back up.
