I started with 87 when I bought my truck, but when the gas prices were $4/gal. I started using 85 in colorado, even though the manual specifically says not to use gas with an octance lower than 87 in high altitude areas. I did not notice a change, no knocking or anything and I've been running 85 for a year and a half.

I run 93, but that is because I have a supercharger/custom tune
I would run what you owners manual suggests or if you have a custom tune, run what is required for that tune

Does the pinging go away if you use higher octane?

Sometimes my truck runs the 87 octane, but i recently changed the tunes and now run the 93 octane. I always use shell, cause it seems to run the best in my truck.
Like many of the previous posts have mentioned, unless your truck is tuned to run on a higher octane gasoline, follow the owners manual on octane ratings.
In the Higher elevations out west, I have run the 85 octane without any issues.
