I'd just go with the minimum listed in the manual. Don't think there's any benefits from putting premium gas into a low compression engine, just never go under the suggested level.
No worries.Thanks for the input! I've since then been following what the manual has called for. Like a lot of you, I've been at a few Grom forums as well, and I was surprised to see some owners/forum posts saying they actually use higher than 87. Which is what prompted me to ask out of curiosity, I'm sorry if I came off as clueless on what fuel to use.
Fang has been an absolute guru on these forums, so I was definitely looking foward to your civilized, prompt, informal and friendly response.
Your pumps show the RON (Research Octane Number) ONLY. We get RON+MON/2 for an average of the two measurements. Why is this that way? Because, Government!!!! :wink2:FangShui,
I have been to the US many times and I have noticed that your octane rating seems to be lower.
Here in the Philippines our regular unleaded gas is rated 93 octane RON. Whats the difference between
your octane rating and RON?
LOL!I have never seen so much information about fuel octane in a thread before. FangShui is a guru !
Ethanol-free gas is best, but can be hard to find. There's only 1 place in my city that sells it (not counting Race Gas, at $9.00+ a gallon) and it's very pricey.The gas station nearest me has ethanol-free gas in premium only. So that's what I go with.
