5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Since i bought my 2008 camry se v6, i been putting 87 gas. Recently i started using 89 and noticed different in how the car drives. It seem acceleration is better with 89 gas instead of 87. Looking at the manual, recommendation is for unleaded gas only. So why it feels like it's driver better with higher gas when car is designed for lower gas?
It's largely your imagination. It might account for perhaps 1 additional horsepower which would hardly be measurable by test equipment let alone an untrained human.

Oil Company conspiracy........
Try 91, 93 and then 95 and it will really feel great.
Doesn't higher octane gas require higher temperature/pressure to detonate? Wouldn't this reduce performance in an engine designed for lower temperatures/pressures? The slower burning, higher octane fuel can also lead to carbon deposits if it is not completely combusted.
I primarily use 87, but occasionally put in 91. Maybe some of you think that there is no difference in performance between the two, but I definitely see a difference. Not enough to justify the cost difference, but still very noticeable.
10.8:1 is not low compression except maybe to kids.....
10:8:1 is certainly LOW enough for Toyota to suggest 87 octane to be use, they would have recommended 91 or higher octane if by your definition it ain't no low compression.

What is your mileage increase when using higher octane gas? Seat of the pants evaluations are to subjective.
There's no way that you're actually "feeling" the difference.
10.8:1 compression is not low. The engine being made of aluminum, electronic fuel injection, and efficient cooling systems are just a few reasons why Toyota and other manufacturers can run a high compression ratio like 10.8:1 without detonation on 87 octane fuel.
Running a higher octane does take longer to burn and can lead to more deposits.
I'm guessing that the OP's car is loosening up and feels more powerful, but it's not the extra 2 octane causing this.
not on the camry but in my other car i used 91 premium all the time but when gas prices shot up i went to 87 and i did feel a difference. not so much in hp cus its not going to miraclely add 20hp but i feel it in acceleration. better detonation using 91 than compared to 87.
