OPTI - 2 ???? I use it in my BridgeStone 35cc . This summer, I was pulling my boat with my motorized bicycle and obviously the most heavy load ever that my motor has been under and my motor ( 5 years since May 2013 ) is still running. I run OPTI at 25-30 : 1
Yep I'm glad that i'm still here to talk about it, cause this summer, i did a 5 day 107 mile trip with my Dagger Mumba kayak , alone !!! From Drayton Valley to Edmonton.
I almost died twice. Yep, between Devon and Edmonton, the river is big, but almost like a lake. Hardly any current but in Drayton Valley, and for 50 miles, that river is a nightmare...rapids round evry corner. Next year , if i'm still around, i wanna do a Rocky Mountain house to Edmonton twice as far and i hear that the river up there is even worse.!!! ( NorthSaskatchewan River )
Anyway, back to the topic, and yes i use OPTI 2 and it's great oil,
