What gas octane are you running? High Test? Mid Grade? or 87 octane / plain old regular?
I use regular, 87 octane as that is what is specified in the manuals. I also pour <an ounce of Marvels Mistery Oil in every fillup for more top end lubrication.
For a street the dealership said 93?
Owners manual and service manual both indicated 87. And that is at sea level.
My dealership told me the same thing. High octain. But the book says 87. Ive been running high test. Maybe ill try 87 and see if it makes any difference
This is so true i have seen many articles and information that show how useless going with higher octane is when it's not required. Best to go with what is recommended for it.The factory is almost always correct and it does provide the minimum octane rating that should be used. The problem I find is with those that think a higher octane has more energy improving performance and that is a false belief. The octane rating has nothing to do with the amount of horsepower produced by the engine. Higher octane will not hurt an engine but it won't increase HP either.
