It always amazes me reading the oil threads Poster spends BIG $'s on buying a saw, more than likely a Pro jobbie, & maybe then spends more $'s having it ported , then makes a post saying that he's going to run it on Wizz Pi** Twin overhead tool bag mulched cr** at 700 to 1 2T cos' he's read some where or some ones told him that this is the way to go & the reputable oil is too expensive if you mix it sensibly at 32/40/50 to 1, & to quote the ad it must do what it says as it's on the tin/bottle. I fail to comprehend any one spending all those $'s & then ruin it for 50cents worth of a GOOD oil,or increasing the amount mixed Having been involved with 2 smokes in bikes (road racing) saws & other small engines of 2t type for getting on for 60 years I have never come across an engine failure that could be attributed to having to much oil & if you read Bells tuning books he has proved that the more oil you pour(within reason)into it the harder it will run, & more often than not produce equal if not more power. as he states & I found it so towards the end of my racing days ,it seemed more important to have less oil in the mix than actually winning the race To sum up my ramble, I reckon it's better to spend 10/20$' s on oil than 100's of $'s on rebuilds + the down time on the saw Rant over, y'all have a safe sawing 2015
