If you lived over here you would be running it on the lowest octane we sell - recommended by by the manual. Were paying like £1.06 per LITER for regular, if you came over here and filled up the same you would be putting in super unleaded or super octane and be paying like £1.16 or more. Use what it says on the tin, count the pennies and watch the pounds grow.

My 2000 Gix6 is suggested for 87 [(R+M)/2] and that's all I use.  I am however cautious of where I fill up.

Why so?

There has been incidents of "bad gas" going round which for some reason or other dont feed the car like they should and break shaZam!.

People associate high octane fuels with more power......not strictly true unless the high octane fuel goes in a high compression engine. Using anything higher than the maker recommends is a waste of time and money in a stock bike engine, particularly in a 40 year old, air-cooled, slow reving 4 valve engine with an 8-1 comp ratio and " **ck-in-a-shaZam!-sleeve clearances" like the GS has. A higher Comp` ratio and a higher RON will give you a bit of extra power........but higher RON on its own does sweet FA except empty your wallet quicker.

89 'cuz haynes says run 'mid grade'

And Suzuki's US manual says run 87.  You'd rather listen to Haynes?

European and US RON gradings are not the same and should not be confused. US RON numbers are lower than the equivilent European figures......So it follows that a euro` mid grade will equate to a US low grade.

I was running 91 because I didn't know what the octane requirement was.

But now that I know it's 87, I'll use 87, thanks.  I know there are zero benefits, (and possibly some downsides) to running premium on an engine that wasn't designed for it.

Premium is NOT better fuel, it's different fuel.  In fact, calling it premium is false advertising, and causes people to use it when they shouldn't be.  The only thing premium about it is the price.

Welcome to the Far Side. Out here, stuff that makes perfect sense over 'there' seems laughable. Take for instance the phrase "Sports Utility Vehicle". Over here it's lunacy. Over 'there', it's 'cool'.

Also- "I filled up with Premium gas, and put 104+ Octane BOOSTER in. I think I have more horsepower now."

or- "But she can't be pregnant. We only did it for a little while."

maybe even- "Man, this new Suburban at 0% interest is a much smarter deal than a 5 year old crapbox that I have to pay CASH for !"

Enjoy your new knowledge, and the pleasure that knowledge brings. It is such a fantastic thing.

Round of applause for this man and his way of thinking, couldnt have put it better myself

Regular like suzuki reccomends

I´m running 95 octane, cause here in Sweden you can only choose between 95 or 98.. 

Checked the manual last night. Glad to know ive been wasting my money. The shop told me to run 91 because it was a cleaner fuel. Guess im running my last tank of 91 now.

My bike and I both run on beer justnot St the same time

Hmmmm, I bet my bike bike could run on the vodka I drink....................................ehhh screw that, vodka cost too much.

So does beer but that does not stop me.  I would be a rich man if I had all that money back

Beer... Vodka... Psh!  Captain & JAGER!  Bombs away!  Jager-bombs are my octane booster! 

Omg I can't drink rum
