302 gas
I'm sure this has been posted before, but it wont let me search and im having an argument right now about what kind of gas to put in a 96 f150 with 4x4 with the 302 engine. Is 87 good enough, or should a higher grade be used? Thanks

The purpose of high octane fuel was to slow or eliminate spark knock in high compression engines. It has a lower flash point, so it does not tend to pre-ignite as easily.
High octane fuel is a waste of money in a low compression engine. Does not provide better MPG. Only run it if needed.
As yellowjeep76 said, let your engine's spark knocking or lack of it, dictate the octane rating you use.

My 92 5.0 never pings on 87, BUT, I find that it pulls my snowmobile trailer up the mt pass better with either mid or prem fuel, it's not a huge difference, but you can tell. My strategy is to keep mid or prem in one tank and reg in the other and switch over when I hit the hill.

My ol' 88 F150 pings like crazy if I run 87 octane and the engine is bone stock. I'm too cheap to keep filling it with 92 octane gas so I just live with it as it only does it on the highway.
