91 and 93 octane

I wanted to know if a 2000 v6 can use 91 or 93 and if so how much will it help with performance (without a chip or tuner for now)

None will help without a tune. A tuner or chip just holds the file or tune. You should see about a 10 HP different once u get a tune

Re: 91 and 93 octane

+10 For everyone else-
Without a tune, you use 87 octane.
Every oil change, pour one can in the gas tank and suck one can up da upper intake manifold. Seafoam dat beeaughch.
Any time some questions using higher octane than 87, the answer leads to dirty clogged up intakes. Use the Seafoam. Install an oil seperator.

It's generally using LOW grade fuel that causes carbon build up and clogged injectors. Using a higher grade of fuel may not net any performance gains in an untuned vehicle but it burns cleaner and more efficiently leaving a cleaner engine overall.

I had 93 the day before I got my tuner and I felt like it helped my throttle a little. Might have been just in my head tho

Re: 91 and 93 octane

What I stated is correct. It's documented. It's what I believe, anyway.
What will happen if I use higher octane gas than I’m supposed to?

A few things. For one, you will be wasting a huge amount of money paying for high octane gasoline. Second, your car will not run correctly, whether you notice it or not. Higher octane fuel requires more heat and more precision to burn correctly. If your car is designed to burn 87, it will not burn 93 correctly. Third, your gas mileage will suffer. The inability of your engine to burn the higher octane gas correctly will cause your engine to produce less power and thus will require more fuel to perform at the same level
____________----------_________
For most cars the answer is NO. Higher octane fuels burn slower so unless you can increase your initial advance you will not see any difference. Also when a vehicle is tuned to use lower octane fuel a higher octane will create carbon deposits and over time will cause engine ware, overheating, and poorer fuel economy. Todays igitions are computer controled many are distributorless so we shade tree mechanics can't mess with them. Many of todays vehicles recommend 91 octane but can use 89 or 87 if you don't hot rod them or over load them, more than two people.
