Harris-Dobson Posted November 12, 2009 Share Posted November 12, 2009 I need to top up the oil on my R125, but I cannot find anything in my manual or on google that actually says what oil I should pick up?! can anybody just give me a nudge towards any particular brand - specific oil?

KirriePete Posted November 12, 2009 Share Posted November 12, 2009 Surely the manual gives you the oil spec? "10w/40 mineral/synthetic/semi-synth to API Specification SL" or summat like that? As for specific brands, all the quality ones are much of a muchness and should readily mix - so what's in the engine now? I've used Halford's own brand semi-skimmed bike oil for ages with no problems. Rough guide: 1. Don't mix types if you can avoid it - mineral/synth/semi-synth. They should work together OK, but why risk it? b. The API spec is the one you need to check - if your manual says SJ or better, don't put SG in it - but vice-versa is OK. The order is on the second letter, so SA is the oldest, SM (?) is most recent - S is for petrol engines (Spark ignition, maybe?). iii. Don't be tempted by cheap car oils - most bikes don't react to well to them (long diatribe on friction modifiers and wet clutches ... avoided).

YamaGod Posted November 12, 2009 Share Posted November 12, 2009 It is in spanish , but is the service manual for your bike. Where it says " ACEITE DEL MOTOR" ( ENGINE OIL) you can read : TYPE OF OIL : SAE 10W - 30 , SAE 10W - 40 , SAE 15W - 40 , SAE 20W - 40 , or SAE 20W - 50 . RECOMMENDED DEGREE OF ENGINE´S OIL : API service type SG , or superior , NORM : JASO , MA ¿ Or is it the brand , you want to know ? YAMALUBE FULLY SYNTHETIC 4 STROKE MOTOR OIL PART NUMBER : YMD-65011-01-02 Link to comment Share on other sites More sharing options...
