2-stroke oil,what works,what doesn't

[SlowpokeMoses]

I've got 5 motors all running Stihl HP Ultra. Never had a problem with any. However I think i will be switching to Redline this year as the only Stihl dealer around is a John Deere dealership. Oil there is pretty pricey, so ill save some bucks and get some Redline at the local cycle shop.

Mobil 1 racing 2T, works like a charm.
But when I come to the US, I'm using the Stihl HP Ultra, awesome oil.

Okay........is this clean or would this be considered heavy deposits on the crown of the piston and top of the cylinder? This is right at 25 gallons Stihl Ultra HP and 89 pump gas mixed 38:1.

That's my plan for the 2015 season....switch to Redline oil. The Ultra HP has been a good oil tho

I use AMSOIL at 32:1 and all of my engines output extremely black oily mess! Is it the oil is not getting burned sufficiently or too much oil in the mix or......?

I use Amsoil 100:1 oil mixed at 50:1.

Anyone use castor oil? I used to run it in bikes and my ski, but haven't in quite a while. Race gas and castor oil always had a sweet smell to it. I was going to pick up Maxima 927 castor oil last time I drove past the motorcycle dealership, but they were out. I'd think I would want to richen my mix up a bit, probably more in the 32:1 range, compared to a full synthetic.

I tried Klotz supertechniplate(sweet smell) for a while in one airplane engine....got a ton of carbon build up in it, it's more for liquid cooled engines tho

Very simple: If Stihl Ultra HP is good enough for landscapers who run their wackers and blowers 8 hours a day non stop, it's good for my planes that maybe get a few hours of runtime every year. I'm a noob, so I have soooo many other things to worry about. 40:1 is what I use. Now rip this noob to pieces, please! I need some entertainment while I'm drinking tonight!
