Fuel:oil mixture for RM 125 B
« on: January 26, 2014, 09:45:25 am »
Hi guys,

Fuel:oil ratio for RM125B?

Owners Manual states 20 to 1, others advise 32 to 1.

Thanks for your continued advice and support.

Cheers

If you want it to last use MAXIMA 927 Castor at 30:1 and run 98 octane

That's what I use. My B doesn't go too bad  ;D

This motor is fresh isn't it? The secret is stick to whatever oil you decide on. Don't chop and change.

Change oil brands when I find something better, showed a fellow how different oil made less spooge at 25:1 than another oil at 50:1. What isn't in doubt is the castor synthetic blends out perform plain synthetic or mineral oil, 927, A747, Motorex castor synthetic blends are all very good oils. 20 or 25:1 is best for HP.

Buy or build a bloody fourstroke before all this talk on oil ratios and what the best brand is does your head in. It's an age old conversation that goes round and round....
