Do I have to run 91 octane like it say's or can I run regular 87 octane. I have been running a mid grade 89 octane with no problems, pinnging ect. Just would like to know.
You don't have to do anything they tell you in the manual, but you should consider that the recommendation wasn't put there just for grins.Do I have to run 91 octane like it say's or can I run regular 87 octane.

I've been quite lucky also using 87 mainly in the city driving conditions. I'm at sea level, mainly flat driving conditions. Went for a 400 mile trip though the mountains on Thursday and ran 87 also. I had ear plugs in so I would of never heard the pinging if there was some. I averaged 44 mpg. Now I should do that trip and compare my gas mileage with 93.I always run 89 in all 3 bikes locally, runs smooth & quiet , no pinging , but elsewhere , will use the highest octane available instead of the 85 or 87 they would have .
I run regular octane for over 140K miles.... Of Course mine is the wonderful ST1100!Do I have to run 91 octane like it say's or can I run regular 87 octane. I have been running a mid grade 89 octane with no problems, pinnging ect. Just would like to know.
I've got a $25,000 boroscope instrument at work that I can borrow and then explore the engine through the spark pug holes and also the oil pan drain hole.Blrfl said:So then there's the burning question: Who's done a teardown and inspected the valves and pistons?

Al- I see that you are in B.C. so would that be 44 miles per imperial or U.S. gallon? I have averaged 56 MPG imperial (47 US) on my 09 since day one using 91 octane. This seems to be in line with what others post for fuel efficiency. The reason I ask is that only once did my mileage drop as low as 44 MPG imperial and that was on a tank of 87 octane. It was only one tank so it is not a good test but when I saw your mpg I was curious about what gallon you are referencing. If it is imperial the mpg is not very good and I would be curius to know if that is due to the regular gas. I should try a few more tanks of regular to see what happens. I have always used 91 octane to date.I averaged 44 mpg.
This would be US/GAL. Convert it and I would be 53 UK/GAL. Or as we talk up her 19km/litre. This ride was through the mountains, so I'm thinking I could boost up my mileage if I was riding on flatter surfaces.Al- I see that you are in B.C. so would that be 44 miles per imperial or U.S. gallon?

This....fresh fuel is more important to me than the octane these days.The 1300 like 91 octane better then 87, I do run 87 sometimes in my ST1300 when at stations that do not do a lot of volume as my thought is that the 87 will be fresher then 91 in those locatons.
