Just would like to know if I should change from using 85 to 87.

I'm driving at 3000 to 10000 ft elevation and regular here is 85, plus is 87 and premium 91.

Also Just took a trip and was about 200ft above sea level and I used 87 since that was regular and my car felt like a rocket ship lol

Just would like some input.

Thanks

This is probably a question best answered by a local Toyota dealer. They should have the best knowledge on local conditions and fuel qualities.
