braddon Posted October 19, 2009 Report Share Posted October 19, 2009 I am currently putting 100ml of oil to every 5 litres of fuel. I thought it was semi synthetic but looked and its non synthetic at all. It smokes a lot mostly on start up but still smokes white smoke when running normal. What ratio should I use as i presume its runnign too rich. Thanks Quote Link to comment Share on other sites More sharing options...
chewy Posted October 19, 2009 Report Share Posted October 19, 2009 All the "official" mix ratios are available on beta uk site I imagine. I've been running 80cls to 5 litres for last 20 years on any of the modern makes you can think of with no problems (at least a semi synth) ..many will say leaner on fully synth. I wouldn't want to run my lawn mower on std 2 stroke oil ..only because I'm fussy about things like this. yours is a very broad question though so you will get a variety of answers.

sawtooth Posted November 6, 2009 Report Share Posted November 6, 2009 I run my 2003 Rev3 270cc @ 70:1 I always use high octane fuel and only ever get smoke if i open it right up in 5th or 6th. Quote Link to comment Share on other sites More sharing options...
