Yet another gasoline thread

[dcartwright]

I have an '05 Turbo Lite convertible. I've always run it on regular unleaded. Over the years I've read countless threads about gas. I've just read back through a couple dozen of them to see if the answer to my question is there.

Consensus is the turbo lite should run on regular unleaded and the GT should run on premium. There's some disagreement as to whether or not the GT can run on the lower grades. Some say not to go below mid grade. Most people think there's no pint to running the Lite on premium.

I did see one post that in a thread that said the '06 Turbo lite is recommended to run on mid-grade even though it's the same set up as the '05 Lite.

So here's my question: Is there any benefit to runnning the Lite on mid grade?

After reading dozens of gasoline threads, the consensus is that the Turbo Lite was designed to run on regular grade fuel and putting in anything above that is throwing money out the window.

Adding Stage 1 to the Turbo Lite brings it to the GT level and should have premium fuel. Less than that and the computer will compensate for the lower octane but power will be reduced. The question is, why add Stage 1 and be cheap about what grade of gas you use?

I do not believe there is any advantage to using higher octane in a turbo lite.

NO. Mid-grade is only 2-octane higher - and should be discontinued altogether; I'll bet it's sales are less than 2% of all gas sold. In most places it's .10 to .12 higher than 87. Premium doesn't seem to offer the Turbo-Lite anything for the extra $. I've tried it several times with no noticeable difference.

You wont until 16ish psi and you start getting serious knock and pulling timing
