You are right, we get the 87 too.

Try it on a highway run and compare. If you get better mileage, then
compare the amount like I did. On our 88 Cherokee 4.0, it shows no
benefit.

My owners manual even says to use high test when fully loaded or running
hard.

Maybe I will then just to see. I was always afraid to feed it some in case
it decided to get used to it and then thumbed its nose at the regular Citgo
