Just remember when yall do this drive the car like you want it to run afterwards. You are training a child how to walk basically what you are doing.


If you have your powertrain warranty keep in mind by doing this it shows you did this fuze pull. They may ? why you did this.


Most have done it after having 87 octane in there cars therefore doing a fuze pull reset your fuel trims.

Yes! There is a significant difference in the way the car drives. The idle has smoothed out as has the engine at all RPMs. I didn't have a chance to open her up but if that's the only difference, I'm happy with that. If there are a few more ponies under the hood too, so much the better.

Thanks for the tip!

A must do for everyone! Thanks!
Glad to see it was helpful.

I bought my car with 5k on the clock and pulled the fuses at work and let it sit for 3 hrs. I really didn't notice any change so I can only assume it's always had 93 octane.

Is there an octane rating that defines low and high octane fuels? Around here, 91 octane is about the best that can be bought. I see some people (Strick) uses 93 octane fuel.

So what is low octane and what is considered high octane fuel?

They are rated by a formula that defines the blends in the fuels. from 87 to 89 to 91 to 93 octane. They vary in many areas even different states and can depend on "Re Formulated" fuels for areas not meeting air quality standards.

It can all get very complicated but bottom line is just find the best "Branded" fuel with all of the additives that may or may not be included in the "bargan" brands. They cost a little more but belive me, you get what you pay for.

The higher the octane the less chance of engine knock that tells the ECM to retard the timming and thus lowers performance. "Pinging or engine knock is bad, it can damage your engine but most engine designs today have the means to compensate for low octane.

Hope this helps

APEX CHASE....do you happen to know of any simple power gains such as this for the v6 engine? i understand what u are saying about the fuel trims between 87 and 93 and the v6 recommends 87 octane so i doubt that trick would work for me. ive also heard that you may lose performance in the v6 if you use 93 octane? anyone else heard this?

JWD621:

Thanks for your reply. The information is helpful. I'll be steering clear of any gasoline rated less than 91 octane as long as higher octane fuels are available.

Your welcome, just remember not all 93 octane fuel are equal. Try to buy "Branded" well known national brands to get all of the additives you will need. You will never have to add anything else from the auto supply if you do stick to the major brands.
