Stihl 4-mix engines

[L0giX]

Hello all

 

Just wondering what 2stroke oil people use in stihl 4-mix engines..

Just about he get a stihl kombi km130r and getting a little confused as some people use any old oil and others say you need fully synthetic stihl oil or it leaves carbon deposits.

 

Any recommendations and views?

I have changed to the stihl HP ultra oil since buying a km130r. It runs on the other stuff but I find it seems a bit sweeter on the ultra. The ultra is designed for the 4 mix engines. Not that much more expensive and I use it in everything now.

I use API-TC, JASO-FC, ISO-L-EGD rated synthetic oil.

I hAve just carried on with a normal mix. The red oil. And my 4 mix trimmer runs great. Had it for 4-5 years

My first 4 mix the valves clogged aparently because if the use of regular stihl 2 stroke both my km130's have been nothing short of a nightmare and I would strongly recommend finding an alternative machine...

Ditto, I switched to HP Ultra as my blower has a 4 mix engine and its brilliant. I now use it in everything and it all runs sweet and much less smoke out the exhaust.

How much is it for 5litres roughly?

Is it the green stuff?

Cheers

if its the stuff i have just been looking at its about £20 for 1l

 

that's mega pricey lol... you can get 5l oregon semi synth for about that.

FD is obviously suitable too...

Yep that's them. Had BR600 backpack blower; suggested to run full synth i.e HP ultra et al or expect valve issues. Stilhl had loads of warranty work due to this issue.
