I tend to run the motors a little rich in oil to begin with, with any engine (car/bike) were told to run in for xx amount of miles and keep revs low, of course chainsaws/strimmers need to be rev'd up fast when used, so my way of thinking is more oil in the mix, hopefully protects the engine a little??

 

'Running in' needs a small amount of metal to metal contact to bed things in. So converse as it may seem, putting extra oil in the mix throughout the running in period is not beneficial and possible detrimental.

 

When running in a motobike you keep the revs low and slowly build them, but also use plenty of engine braking. Diesels tend to like the be thrashed from the off, and perform better like this, in my experience.

yeah i see what you mean i will start off with 30:1 and not the 25:1 mix see how i get it on will use it in my own garden for now and see how she it preforms

I would recommend 40:1 if you're using stihl oil, you forget that the manufacturers assume the purchaser of this machine will use cheap 2-stroke oil

yeah true

Seriously guys, if using a modern 50:1 oil such as stihl,use it at 50:1 from the outset whatever the machine. These oils are designed to be ok at 80:1 even, so 50:1 is ultra safe.

 

Too much oil leaves deposits on the piston crown and in the exhaust.

So gardenkit-- it be fine using 50:1 even tho it says 25:1 yes as im using stihl hp oil

go and get some aspen and run it on that from the start premixed and will run better on aspen than normal 2 stroke all my kit runs on it and works fine

I have used 50:1 in every 2t machine I have used, serviced, repaired and sold in the last 10 yrs, and thats 1000's of machines.

 

Never had an oil related problem.

 

For the first 81/2 yrs I used and sold Rock oil, as I still do, but for the last 18months I have favoured Aspen, which is 50:1 mix as standard.

been running her 50:1 and she runs lovely
