i usually run 91 octane. i cant afford to get anything higher at the moment. gas prices are crazy in canada right now. where i live, in vancouver BC, it just hit about $1.25 a litre....i remember when i first got my car, it was like 60cents a litre and that was considered high......pfffft. haha.

Professional Fuel Injection cleaners
 

I've heard some good things about B12. I used it years ago to clean carbs with.

At the shop we use BG products for all the fluid services, with machines.

One called MI3000 (now CF5) is 4x stronger than what you can buy at parts house. Its for maintaining the system, put in tank about every 10-20 fillups. We sell it for $10 a can.

For the air intake and injector service, 44K is 10x stronger, and used when a dirty system is a problem.

When I first got my licesnse (im only 19, BTW) Gas was under 1.50 here in NJ. Now its over $3. Back then, with my 83 olds cutlass with at least 50 hp, I could get 5$ worth, and drive around ALL day. Now 5$ will get me to the mall and back. Haha. I totalled it up today, I got 10$ of gas from below E at $3.02(3.3 something gallons), and I drove 74 miles And now its below the E line. This is driving in grandma mode(under 2k rpms, not a lot of throttle). So these cars can be good. Oh that averages to 22.4 mpg.

Thanks mrnickleye. Good info.

I feel my fuel system is pretty dirty so I will be looking into getting some of this.
