Fuel Grade
Just trying to see what folks have heard about fuel grades with their scooters. I have a Buddy 170i and have been told multiple things. First that I should stick with the standard, 87 grade. Then also that it helps engine-life to go with Supreme, 93. I've gone back and forth. Can anyone verify that it makes a difference at all? Or am I just wasting my time?
Thanks.
Thanks.

Because you just fuelled up with un-taxed diesel. If you manage to get it started, don't let the revenue men catch you!BuddyRaton wrote:WHY RED IS RED!!!!!
In the cooler months, I run 89 in the high-compression scoots and 87 in the low-compression scoots. In the heat of Tucson summer, I change the 87 up with 89 in most of the bikes. The Riva 180 gets bumped from 89 to 91 due to its heat sensitivity (Yamaha put a cooling fan on the carb, for Pete's sake).
At what point does a hobby become an addiction? I'm uncertain, but after the twelfth scooter, it sorta feels like the latter...

+1. 90 percent of the time. I believe it's 91 octane here in Minnesota. Sometimes I don't have the range to make it to ethanol free.bgwss wrote:I use no ethanol, which in the past year started being easily available.
I heard reported in the news that, with the recent decline in oil prices, ethanol is now more expensive than the gas itself. Anyone hear the same??

To make things even murkier when it comes to octane ratings, there is more than one way to compute a fuel's octane rating.
The most common octane ratings we are likely to see are:
Research Octane Number (RON)
Motor Octane Number (MON)
Anti-Knock Index or (RON+MON)/2, which is usually shown on the pump as (R+M)/2. At one point this rating was also known as the CLC (Cost of Living Council) octane rating.
Depending where you live, you might find RON ratings at the pump (European Union) or the (R+M)/2 method (US / Canada).
I found out about all this stuff I didn't want to have to know when I first started driving VW vans and couldn't figure out why the owners manual indicated that I was supposed to be running a low compression engine on 91 octane fuel. Once I realized that Germany uses the RON method to compute octane ratings, it didn't take me too long to find a chart that let me know that 91 RON was the same thing as 87 octane when computed by the (R+M)/2 method.

And to stir up this can of worms a bit more...
what about fuel additives/octane boosters, carb/injector cleaners and such?
any use them? do they make a difference?
