the great GAS debate

Gas is a funny subject…especially when its so expensive now. I’ve used cheap and expensive. Here are my findings:
93 octane vs 87 octane
No difference. Runs the same no matter what the level is
Additives
I have noticed a difference in power when using 87 octane and an octane booster….the STP brand in the orange bottle. The truck was more responsive and ran smoother…
I still believe 93 is a waste of money and i think any additive will really give you a performance boost.
Engine temperature vs 87 octane
I have noticed a significant difference when running 87 octane and using a 190 degree (or more) thermostat. I read somewhere that lower octane needs higher temperatures to burn, in case you need some background before you decide to go to the local auto parts store and buy a high temp therm.
The only downside: the engine will be pretty hot…especially in the summer months, so you may want to run a super-coolant additive and/or use a failsafe thermostat.
