I cant tell the difference, weather it's 87 or 91. The only time I put 91 in is if Im going to tow to the desert, just incase it does make a diff.

Makes a very loud knocking noise when accelerating! Put 91 in and it all goes away!!! anyone else experiencing this?![]()
Do you regularly run 91? If so the computer might have to adjust back to 87. I think what you're hearing is pinging. It's not bad unless it's really loud and happens a lot! Run 87 long enough and it should be ok. If not...try 89.My V8 Tundra doesnt seem to like 87 octane. Makes a very loud knocking noise when accelerating!

My '00 has always run on 87 and never pinged or knocked.My V8 Tundra doesnt seem to like 87 octane. Makes a very loud knocking noise when accelerating! Put 91 in and it all goes away!!! anyone else experiencing this?![]()
Ditto. I used 91 in my 02 Tundra, thinking it would make a difference, but it never did. Now I use 87 and save the extra money for beerI've run 87 for the past 6 years and 136,000 miles. Occasionally I will put a tank of 91 in and cannot feel the difference or see the difference in mpg. Don't waste he money, use 87.
Constant pinging is a bad thing. If anyone tows with their truck, consider running a higher grade fuel and you should not experience any problems.Do you regularly run 91?

My brothers 99 3.0 liter Ford Ranger pings like crazy on 87...he's ran 93 for the past 6 years with no problem. Higher octane simply prevents early detonation, which is more important in forced induction motors.
