Just figured I'd see what others' experience was using different octanes of fuel. I usually use premium Shell V-Power (doesn't list octane, I think it's 91 or 93 though), and today I ran out of gas. I came home and there was a jerry can sitting out back for the lawn mowers full of gas. I assume it was 87 octane. So I poured out 1L, mixed in ~40ml of oil (for just under 32:1), and noticed some very, VERY obvious differences:
The negatives:
Throttle response was absolutely terrible, even at speed if I went WOT it would bog down for a second before speeding up, and takes several seconds to lower back to idle revs, this does not happen with the Shell V-Power, response is quick unless I'm at a complete stop and idling.
Noticably less power, it could barely haul me up the hill I ride up every day, and takes a long time to reach top speed, the V-power is able to haul me up the same hill at 35kph minimum, 87 octane it slowed to the point where I could have pedalled to help it along.
Idles rough
The strange:
My max revs is... way... way higher, though the vibrations get pretty rampant again, it was ridiculous how fast it would go. It simply did not four-stroke at all even going well above 65, the Shell V-power four-strokes around 61kph.
I want to hear other's experiences who have tried other octanes at preferably the same oil and ratio (some places dont offer different octanes so theres bound to be people who were forced into using a lower grade).
