I went to hit some gas 2day, is a full servies gas station only, therefor I told that guy I want a fillup with 91, I wasn't looking when he was fill my gas tank, next think I notice, he was fill my gas tank with 87, I stop him right away, and told him to put 94 in. I believe that our ISX50 is required 91 and above, will 87 do any damage is this case?

there is like 1/2 of tank with 87, 1/4 with 91, and 1/4 with 94.

 

no damage...your car is fine. Let me guess? Richmond?

 

Get him fired.

 

You'll be fine... Just fill up next time when you are almost on E.

 

usually Lexus dealerships fill up on regular fuel... so yea u should be fine.. Newer engines have knock senors n what not to prevent problems..

 

At least it wasn't diesel!

 

Don't sweat it, I usually run 87 in my 250AWD

 

Thats not even funny dude. Everybody makes mistakes.

 

MAN. Can't blame him cause I did this myself one day without thinking too clearly. Had a half tank of 87 too. just threw some ChevronTechron Cleaner in there with it.

 

Drive it and forget about it. It's no biggie. No damage.

 

its ok... not reccomended but wont destroy it....

 

bummer, that guy mustve misheard u or somethin...

 

yeah, is in Richmond. (don't like Richmond is a must full serve station) I usually do it myself, but it was a bit cold last night, therefor I let them fill my tank of gas, and this happen.

and thx you all for making me feel better.

 

No harm done. Listen for detonation, not likely you will hear any.

 

just use the whole tank and fill it back with 91 next time......
