lee99780 Posted February 13, 2012 Report Share Posted February 13, 2012 Hi all, I've just become proud owner of a 2009 125 txt pro In the manual it just advises you to use synthetic or semi, no grade specified. Can I use any? Quote Link to comment Share on other sites More sharing options...

dadof2 Posted February 13, 2012 Report Share Posted February 13, 2012 I am slightly hesitant to post on the subject of premix oil because there are many different, often strongly held opinions. I have had excellent low engine wear from old fashined mineral oils like castrol TT, yet significantly faster wear of both bore and bearings using supposedly far superior modern synthetics. You will probably find the standard recomendation for fully synthetic in a gas gas is 1.5% which is 67:1 or 75cc to 5 litre fuel. The recommendation for mineral oil is 4% which is 25:1. My preference is for good quality semi synthetic like Shell advance VSX 2 at 30:1.(167 cc oil to 5 litres petrol) Of the fully synthetics some consider Motul 2T 710 or Castrol TTS to be the best lubricant.

rev3 Posted February 13, 2012 Report Share Posted February 13, 2012 (edited) I have always used a semi synthetic at 75cc per 5 litres and never had any problem. I was advised to steer clear of fully synthetic due to trials engines not revving hard enough to burn it efficiently.
