Whats your choice? Fuel, Oil & Ratio
« on: May 28, 2010, 08:46:19 pm »
Thought I'd throw this one out there, It's probably been here before! Everyone has their favourites
Whats your choice? What works for you?  :)

        1:  Fuel: Ethanol Blend, Unleaded 91, 95 Octane, or 98 Octane
        2:  Product: Shell, BP, Caltex, Ect.
        3:  2 Stroke oil: Motul, Bell Ray, Silkolene, Ect.
        4:  Ratio Mix: 20:1, 25:1, 33:1, Ect
I thought I was wrong once, but I was mistaken.

Caltex's Vortex 98
Motul 800 at 30:1 for the 05 YZ125
Castrol Active at 20:1 for the 75 RM125

I remember the long thread on oil ratios and have been running the RM on 20:1 for the past year as a result of Lozza's views. Just pulled the top end for a freshen up before CD7 and VERY impressed with the internals. Nice oil film, very clean piston crown, minimal wear. It'll get rings but only cos I have heaps of spares and need to use them! Before that I was running the RM on 35:1 with Motul 800 and the wear was rather more than I expected.

I totally agree Graham - after that long thread on oils I have been using Bel-Ray H1R at 30:1 in my 250's - it is much thinner than the Motul 800 and seems to burn cleaner. I am happy with it - others have different views

Caltex Vortex 98 (because I can buy it locally).
Motul 800 (because I can buy it locally).
20:1 (because I want my engines to last).
The good thing about telling the truth is that you don't have to remember what you said.

as Looza says 20 to 1,the motor will run cooler,less fiction,less wear and more power dyno proven cause oil burns along with the fuel ;) ;D

BP 98
Castrol TTS at 25:1   
                              Don`t go throwing rocks at me for using the TTS but i swear by this stuff, i have used this oil in all my bikes since the early 80`s and every engine has been like brand new when i pull them down for a freshen up. Never had a bike destroy itself on this oil.   Peter.

R30, BP98, 30:1, but changing to 20:1, my father always told me 25:1, and in early days of racing that is what l used, because he was an A Grade mechanic, and dotor of Mechnic. so l thought he new best.
so l am going to ask a dumb question, 20:1 ,ratio, 5lt of fuel to how much oil.
When l mixed 30;1, it was 333mls to 10lt. of fuel.
