87 or 91 Octane

[NotApplicable]

This is one of those “you do you” topics. There are a lot of strong opinions and superstitions out there but very little to no empirical evidence, particularly when it comes to the 6th gen 4Runner specifically.

The manual says to stay at or above 87. Do that and you’re good!

Yeah, before the 7% discount at Costco the difference in 85 and 91 octane here is like 60 cents.

Running 85 at altitude gives noticeably worse performance.

87 'cuz I tried 2 tanks of 93 and it didn't do anything better than 87 can do
