So what's the current two stroke oil favorite?

Run an ounce of your preferred brand of fuel system cleaner per gallon and you won’t ever have any carbon.

Don’t even have to worry about adding anything to Dominator, it & Schaeffers 7000 are the 2 best oils for keeping carbon away that I’ve ever seen!!

I'm not too worried about it.
Just my routine.
It's worked well for me.

Maybe you 40:1 or 50:1 guys wont notice, since I'm a 32:1 guy I notice Saber will split out of the muffler more that the Dom under low load from big saws . Both are really good and I just use the one with color I want that day.

Good stuff! I stayed away from dominator because of the amount of info I have read that it doesn’t burn as clean unless it’s in power sports equipment strung / reved out to its max, doesn’t have stabiliser and doesn’t have rust inhibitors. It’s also designed around the notion that race engines are stripped and cleaned frequently?


Then again, I think it’s all just marketing hype and business. Amsoil Saber is perfectly safe in a dirt bike so long as you aren’t stupid and try run it at 80-100:1 why anyone would in any 2 stroke is beyond me though! If you can run bog standard mineral oil in one 32:1 you sure as hell can run Saber at 32:1 - 50:1 in one too

I love how little smoke Saber produces.

I agree 100 % . I think if you look at the heavier viscosity of the Saber , it gives you an idea why it can go leaner , however the Manufacturer clearly recommends nothing more than 50 :1 . I use it at 44:1 in my ported & high compression saws . I may do more usage of Red Armor in a few ported saws shortly brother !

spong is a byproduct of too rich of fuel ratio , which can lower the internal engine combustion chamber temps . This causes the unburnt fuel & oil to be thrown out the exhaust port into the muffler . Unfortunately the excess oil becomes hardened carbon deposits , which can cause various engine liabilities . Either retune you saw or back off to 40:1 and see if it clears up . Lugging or low rpm with any air cooled engine is counter productive , so wicking it up usually helps clearing things up with higher internal temps .

That may help , but with quality oil that has detergency & anti oxidizers , emulsifiers within its additive package e.g.. FD rated your fuel with do the cleaning , if mixed properly within a balanced tuning !

Do they smell the same? Saber and dominator?

pretty well brother !

it's funny that Amsoil now really stress 80-100 only , I stick to 50 :1 on homeowner grade , even with the lower compression so far so good . It makes one wonder if their changing the Sabers recipe , more ester possibly ?

 

[North by Northwest]

Just some of the dumb things I think of when the tune is not behaving,
time for a carb kit on this one next.
Probably pine sapped like the rest of the saw lol.

As for oil, closing in on a gallon of echo and all seems well.

Echo power blend is a quality oil for stock saws , Armor for higher compression or ported saws !

That’s actually shown to not be the case, if you look at any of the saws running 32:1 Schaefer’s 7000, they are clean as a whistle, no carbon anywhere, exhaust port or piston crown.

If you run an ounce or fuel system cleaner in any ratio under 50:1 you will never see carbon buildup with a quality oil. Fuel system cleaners do a much better job of removing/eliminating carbon than the oil can do. This is the 390XP I bought from Stumpshot after 9 tanks RA and Dom with an ounce of Techron per gallon at 25:1, no spooge and minimal carbon. This top end was new when the saw was purchased.

 

[mrxlh]

This is my 55 that was run every oil under the sun at 45:1

 

[mrxlh]

This was using a heavy ratio of 25:1 to try to clean it up, 3 tanks.

 

[mrxlh]

This was after several tanks same ratio with fuel system cleaner added.

Wanted to report back on the Saber. Still cant get over how there is just no smoke, but at 32:1 it seems to be producing too much carbon build up. I know they recommend 80-10:1. I’m not confident there. Will try 50:1 next.

For those running Saber in their OPE garden equipment, what are you running it at?

 

[cus_deluxe]

i use dominator now cuz for some reason the place i get oil doesnt sell saber in quarts anymore, but ive used 3oz/gal, which works out to 42:1. easy math, no spooge.

What ratio did you run the Saber at and how did you like it?

 

[cus_deluxe]

What ratio did you run the Saber at and how did you like it?

same ratio, for many years. only reason i dont anymore is the place i buy has gallon jug of dominator for not much more than i used to pay for 4 quarts of saber. i think i like dominator smell better also

I’ve never seen any carbon buildup with it, only a layer that forms right away on top of the piston. I’ve always run everything at 32:1

That’s interesting. I cleaned this piston crown fully, I then mixed up 32:1 Amsoil Saber and put it in my stihl fs36 weed eater. Manual says to tune 9200rpm.

I tuned it to 8700 max rpm which was in and out of 4 stroking - didn’t want to go leaner.

Then I extended the trimmer line a few extra inches to load the powerhead up and that dropped the rpm by 1000 and it no longer 4 stroked.

I then tied a cable tie around the throttle and let it run like that, loaded for 20 minutes (with about 5 minutes of idle and throttle blips to tune it before hand) without cutting grass, just the longer length of line loading the powerhead. This is the result.

I love the smell and colour of Amsoil, but this was disappointing. Then again, if they have designed it to run at 80-100:1 then really I’m the ignorant one trying to mix it at 32:1 and expect a clean engine.

I’m going back and forth in my mind if I should do 50:1 or 80:1

I have seen Richard Flagg do videos on both, 80:1 and it’s basically spotless, not much residual in the crank though, but the saws he’s working in have had 80:1 for years and work hard no provlems. 50:1 it has much more carbon build up and almost seems unnecessary with this oil.

Here is the strimmer, I’d suggest 70% of the piston is clean, 30% has carbon. The carbon is somewhat soft and a bit gooey. Besides one earlier run for 15 minutes, this is the only other run it has had. This piston was mostly shiny clean before this run.
