I ran 35:1 on my 18 with no seizures and no problems last year. It's just a real hassle, even though I'm a great fan cos it ensures 100% that well mixed oil is getting were its needed.
I just got sick of carrying bottles of oil under the seat and constantly thinking I was going to run out!
Now running an oil pump with two more 1/2" holes in the lid!
Technical eh?
