Regardless of what you do with your 365, get that 390 if you can.  100/1 is just too damn thin for an oil mix..............no matter what oil you use.  Amsoil Sabre is good oil, but I'd run it at 50/1 or thicker............as I would with any other quality synthetic.  As has been stated, the 362-372 and 385/390 saw families have a rep for surviving longer with 32/1.  Stick with that ratio in those saws.

I run Redline 2-Stroke Race Synthetic at 32/1, and have done so with various 2-stroke machines since the late 1980's.  Great stuff, and it's produced somewhat near where I live.  I've also ran Amsoil Sabre, Stihl Ultra, and Baileys WoodlandPro synthetic at 32/1 at various times.  They're all good, as is BelRay H1R.  You won't get excessive carbon deposits when running any of those oils at 32/1.  I run 92 octane non-ethanol gas in my mix.

Well, as I sit here right now considering my options I'll probably get the 390, and keep/repair the 365. I may put it in a box for today since I'll have a saw to use for right now. I've seen people with multiple saws and sometimes thought "they need to get their mess cleaned up" and then here I am starting a collection!?! ;-o

I'll begin using a thicker mix today -- probably 32:1 regardless of brand or advertising claims. I see the Redline is also recommended for 100:1 "if the engine is properly designed for reduced oil mixtures" which this one is probably NOT -- and get rid of the ethanol.

I ran it in my 26cc Zenoah powered HPI Baja 5B 1/5 scale RC car at 25/1.  No carbon deposit or lubrication issues to speak of.  That little bugger turns some serious RPM's too.  Kart guys run it at thick ratios as well.  the Racing Kart branded oil is exactly the same as the 2-Stroke Racing synthetic.  Only the labels are different (Redline states that on their site).  The only 'negative' that I've ever experienced with Redline is that some of the guys I've cut with have complained about the smell/fumes.  Bike guys recognize the smell and smile however... 8)

I've read some internet comments stating that Redline 2-Stroke Racing synthetic doesn't provide sufficient corrosion protection (for the bearings and other steel parts) or that it's even hydroscopic (draws water).  I think that's all internet bunk.  I've torn down motorcycle and saw engines that have sat on the shelf for 20 years or more.  These engines had last ran with Redline oil.  Still had a film of oil on all the internals, and NO corrosion.  Redline states that their oil is safe to use with alcohol and gasoline/alcohol blended fuels.  Alcohol is what's hydroscopic, not the oil...

Sounds like a good plan.  You'll need to retune your equipment when switching from 100/1 to 32/1.  The engines will run LEANER (so you'll have to richen them up) as there's less gasoline in a given volume of mix (rich/lean has to do with the gasoline/oxygen ratio).  Any quality synthetic oil will be just fine.  Most important thing is a proper tune and clean, quality fuel.

As long as it will already be in a box, send it to me. I will put it back together with a good crank, new OEM bearings, seals and gaskets for $200.00 plus return shipping.

I notice this little bit of case has been somehow broken off. Is this a "deal-killer"?--or is the case still usable?

The "oil wars " have gone on for decades with no end in sight .A have for years since modern mix oil came out ran at 32 to one ratio with no problems .I will admit I have ran Stihl ultra but not at 50 to 1 more like the little jug mixed with 2 gallons of gasoline rather than the 2.5 it was designed for .

Amsoil might be good stuff but for my preference I think 100 to 1 is asking for trouble .I've cooked one saw in my lifetime .That was from priming with straight gas by mistake not from the oil mix ratio .

Cylinder image with scarring. Piston ring is also seized to the piston on one side. Gasket is as I removed it -- with about a 3/8 inch gap. Didn't know why I could never adjust the idle speed down regardless of low needle setting -- guess it was running lean sucking air through the gap. Compression check when I got it was only about 90#, but it ran great--not much pep on opening the throttle -- just sort of slowly revved up, but when it got spinning it would easily out cut my 455. Obviously a lot more saw even in bad condition.

IMO easy p+c clean up, re-ring, gasket and run her.
