What oil is best? and what ratio?

[EFSM]

40:1 mostly. Initially tried it at 32:1 and 50:1. Ended up splitting the differance.
RA is good oil but its not magic. K2 is a little cleaner and leaves just as much residual from what I can tell.

How good is the stabilizer in K2?

I liook at it like….if you use your equipment regularly you shouldn’t need a fuel stabilizer. If you don’t use it often enough that you require a fuel stabilizer, it doesn’t matter what kind of two-stroke oil you use as you’re not going to wear it out. I don’t know, just my thinking.

I choose to use better oils because 95% of the mixed gas I use is burned in customer saws.

It doesn't have a stabilizer and frankly I don't want one.

Some of the fuel stabilizers supposedly have Polyetheramine. Like marine stabil.

I saw two weird changes in my equipment when using marine stabil in all the fuel:

2 stroke: exauhst ports still had carbon build up, but it wasn't hard, it was the consistency of grainy bubble gum. You could almost scrape the carbon out with yer finger nail.

Once I went to startron stabilizer, the carbon build up in the exauhst port was hard as a rock again.

4 strokes: If I used too much marine stable, I would get a " blue-green stabil booger" that would develop in the fuel filter and the bottom of the carb bowls.

Still using cheap/plain-jane Lucas 2 cycle in all my 2 strokes. Can find it at any O'Reilleys napa or autozone for $9.99 a quart. Year #3 in the saws using lucas.

Funny thing: completely overhauling an 80hp suzuki 550 2 stroke. Oil injection tank full of lucas. Just bout finished out. Compression was a little low at 7000 miles. Ring gaps sloppy, piston skirts deformed and sloppy.

Anyhow, I noticed that the throttle cable is broken! The oil injector pump side if the cable is snapped and wasn't working. I dont know how long this motor has been fed oil metered only for idle, while I full throttle the fker every day.

The bottom end is just fine. No signs of heat not a spec of blue discoloration on the rod ends. So just a routine top-end refresh.

$120 for a freaking throttle cable. As much as a forged piston.

I just use a dash of PRI-G in all my small engine's fuel.

Why? Because of how fast you use it? Or because stabilizer is displacing lubrication?

Some equipment (especially trimmers, both hedge and string, and leaf blowers) is used hard but is very much seasonal. The stabilizer in Red Armor does an excellent job with keeping fuel good for up to a year. I recently dumped some RA fuel that was at least 3 years old out of a rarely-used saw of mine. The gas wasn’t fresh by any means but it wasn’t damagingly stale or separated either.
