I agree with the above, 5w 40 fully synthetic makes my engines quieter and seems smoother at idle, and does not burn any oil , previously i was using 10w/ 40 and still used no oil between 6 month changes, But 5w /40 seems to suit my twinsparks much better than any other oil i have tried over the last 4 years.
I tried 10w/ 60 once for a day and it blew the oil into the breather pipe, it was drained out straight away..
