megawatt Posted January 1, 2013 Share Posted January 1, 2013 I doubt it would need fully synth? Semi synth probably adequate and cheaper. Make sure tou buy a motorcycle oil like Halfords own make. Quote Link to comment Share on other sites More sharing options...
pointblank0 Posted January 1, 2013 Share Posted January 1, 2013 Fully synthetic is really expensive for engine oil mate. Semi will do the same job for lots cheaper Quote Link to comment Share on other sites More sharing options...
Guest Posted January 2, 2013 Share Posted January 2, 2013 The manual recommends a decent quality SAE 10W/40 - fully synthetic oil is completely unsuitable for a CG, for want of a more technical description, it's too slippery. CG engines aren't/weren't built to the ultra-tight tolerances of more modern, high performance engines - using fully synth' is likely to lead to high oil consumption and glazed cylinder bore.As Megawatt posted, something like Halford's own-brand SAE 10W/40 will be fine. The best thing you can do for the CG is check the level regularly and change the oil regularly (rather than spending 20 quid on a litre of unsuitable oil). Also, clean out the centrifugal oil filter located behind the clutch cover once a year. Give her a bit of tlc and she'll last you for years.Rick Quote Link to comment Share on other sites More sharing options...
Fozzie Posted January 2, 2013 Share Posted January 2, 2013 If it was a 15BHP 125 then use fully synthetic but as it's just a CG semi-synth from Halfords will do the trick I use fully synth in my CBR600 as thats a high output engine for a 600. But for an old diversion 600 i just used semi synth. My mate who owns it dynod it at 49BHP so no way did it need super slippery fully synth.
