More like we're getting his whole fist up our wazoos.

I paid $1.489 yesterday for 87. The high in my area was 1.659 for premium, 91. 'Course this is Tayxus...

I shop in special places

to the rest of people, price is around 1.85-2.00+ here.

Ok so what is the diff between US and UK octane rating?

And if there isn't a diff how come the lowest we can buy is 95 octane and you guys get to put cheap bellybutton 87 octane sludge in yr tanks?

And WTF would happen to Rip's BMW lump if he put in the 98 octane good stuff that I used to run my bike on?

The only thing that higher octane does is reduce the possibility of pre-ignition in higher compression engines or supercharged/turbocharged engines. It doesn't produce any more power in and of itself, it basically burns slower. With a higher octane rating you can increase pressure in the cylinders and get more power that way. If the vehicle is designed to run on 87 octane you don't gain anything from running a higher octane gasoline.

There is a misconception by a lot of folks on what higher octane gas will do hence the reason I explained it.

Yep, I said the same thing back in a post about allied aircraft vs lufftwobble and highoctane fuel. Its a compression issue.

Since I have no chemical knowledge of how it all works I'll bow to your expertise. All I know is that when ya twist the twisty thing the world goes a little blurred.

And I swear I can feel the difference between 95 and 98 on acceleration. 95 gooooood, 98 better!

Mark Luper · « **Reply #26 on:** February 20, 2003, 01:39:46 AM »

Well Swoop, if your bike has a sensing unit on it like most of the newer cars that sense impending pre-ignition or detonation and reduce the timing to compensate, that would explain why. If it doesn't then it is your imagination

. Kinda like washing the car and it seems to run better and quieter...

Probably. Yamaha R6, first bike I ever owned with an engine management system.

But then again the bike before that (Kawasaki ZXR400) also went better on super. Catagorically. Just by taking up the throttle slack it could cruise at 85mph......on 95 octane you'd need more throttle to cruise at the same speed. No engine management on ZXRs........

Do this little experiment:

Ok I live in a small town in the middle of the mountains so this is what we do for entertainment.

I had a 99 Toyota tacoma, wanted to figure out if the high oct. stuff really made a difference. Ran 3 tanks of the "cheap" stuff and averaged the MPG (21) Ran 3 tanks of 92 oct and averaged the MPG (24) And felt like I could notice the difference in power. If you work the difference in price/gal and figure out how much it cost per mile to run it was cheaper in the long run to buy the high oct. stuff. Told my friend about this and he tried it in his 92 Chevy with a 350 v8, worked the same for him, now runs the 92 oct.

However I tried this with my 2000 Chevy s-10 and my 2001 toyota 4-runner and there was no difference in MPG. Go figure?
