A two part ? Super Unleaded Gas & A Shift Light

The higher the octane, the harder it is to ignite. Higher octane fuel is used to prevent pre-ignition. Pre-ignition is when the fuel ignites before it is supposed to putting extreme stress on the motor. Pre-ignition is commonly called detonation. Unless your car was designed for or is tuned for a higher octane, you will get the best performance from plain old 87. Since the higher octane fuel is harder to ignite, running an octance higher than required may leave you with unburned fuel in the combustion chamber which may wind up leaving deposits behind and possibly fuel contamination in your oil. Bottom line is it is just a waste of money.

I ran 87 in my car until the blower went on. Never had any issues.

As far as a shift light goes, look into the raptor. It's ~ $85 bucks and you just splice into your computer. That's what I'll be ordering for my car.

Agree on the raptor shift light, no adapter needed.

No need for premium unless you reflash your computer with a performance tune.

unless your having pinging problems on 87 or your tuned then no point in running super.

Raptor shiftlight is the way to go

dont know anything about the gas question. but for shift lite raptor, just installed mine last week and it was cake.
