What do you think about B12 Chemtool?

"400-450kms a tank. Now with my fixed HG, I get about 350kms a tank..."

that is 240-270 miles a tank, and then 210 miles a tank...and if the tank is really 18 gallons, that sucks ass. thats 13-15 and 11. something. My monte carlo which was a carbed 350 got better than that when i didnt race anyone.

yea i drive my car hard sometimes. no wonder i have so many problems haha.

the original MPG for the supra

MPG (city)----------17

MPG (highway)------23
MPG (combined)-----19

I while back, I converted all that into KM's, and if my calculations are right, i should be getting about 400kms per tank....I dont know if I am right...so I think I am in the normal range...My car is weird haha....before and after HG kms, lol.

Sounds like you're running on some very crappy fuel there - granted its cheaper - but what octane? I fill up with 95 octane and get 375miles on a tank with careful driving, or 99 octane and get an extra 20 miles or so out of it. This is the Research Octane Number, not the Engine Octane (which i think you use in the US)

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.

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.

http://www.bgprod.com/products/fuelair.html

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.
