chewy Posted March 20, 2009 Report Share Posted March 20, 2009 i dont run the lawn mower with that sort of mix... i guesse they covering thier arses .. so far as I know most people run sythentic at 80 to 1 the conversations tend to go that more oil = less fuel = more air mix = running weaker = hotter bla bla bla Quote Link to comment Share on other sites More sharing options...
gjbiker Posted March 20, 2009 Report Share Posted March 20, 2009 Have a looky 'HERE'. It should let you decide what's best? You'll notice there's nothing less (more?) than 50:1 (2%). Hope this helps? GJ Quote Link to comment Share on other sites More sharing options...
b40rt Posted March 20, 2009 Report Share Posted March 20, 2009 I ran at 32:1 for 20 years, same piston, same main bearings. You have to make the decision if the nano second in engine response is worth changing bearings/pistons if you run at 80:1. Quote Link to comment Share on other sites More sharing options...
godzilla Posted March 20, 2009 Report Share Posted March 20, 2009 I run my 05 sy on motul at 70:1 never had any problems, i was advised not to run it too rich as the silencers are not re-packabls and WILL bung up if run TOO rich. Quote Link to comment Share on other sites More sharing options...
pete_scorpa3 Posted March 20, 2009 Report Share Posted March 20, 2009 I've run SY250's on Silkolene Synthetic for the last six years mixing 16mls to every litre of fuel. This means that I measure out 80mls of oil for every five litre can. This gives a ratio of 62.5:1 I've yet to have any engine issues even when I've ridden in road trials. However, my advice would be to use more oil to start with and see how your machine performs, you'll get to a figure that you are happy with after a while.

jam Posted March 20, 2009 Report Share Posted March 20, 2009 Here is another option, Castrol TTS at 60:1. Its fully synthetic and I've had no probs. Enjoy!!! Quote Link to comment Share on other sites More sharing options...
dfwilson Posted March 20, 2009 Report Share Posted March 20, 2009 My 03 SY-250 has been fed with Motul 600 or 800 full synthetic at 80:1 with nary a problem since new. Unless you use smoke as a weapon or for subterfuge to baffel the observer every one in the que will appreciate you using 80:1 Cheers Doug Quote Link to comment Share on other sites More sharing options...
g520 Posted March 21, 2009 Author Report Share Posted March 21, 2009 Thanks guys. So I definitely do not have to go 40:1. Makes me wonder why Scorpa recommends it. Maybe they want to recommend something extra-save like Chewy said. I have been using Ipone semi-synthetic for years on my enduro bikes with great results. I guess I will use it for the Scorpa also and try mixing apprx. 65:1 to start with. Quote Link to comment Share on other sites More sharing options...
drhud Posted March 26, 2009 Report Share Posted March 26, 2009 Maybe it got lost in translation and they meant to say use 2.5 ounces of oil to one gallon of gas?? Quote Link to comment Share on other sites More sharing options...
