What oil is best? and what ratio?

[bwalker]

I am shocked by what I see in this saw. You'd think that I ran straight gas, its that dry

Check for seperation of the oil from the fuel.

25 to 1 is lean i bet 40 to 1 is wetter if you tried it ,i could be wrong though

Mixxed in RatioRite then ran

25:1 with OTP is still sopping wet after 6 weeks .........seems like the Lucas just vanished

I've got no interest in slamming an oil, but I ran it exclusively, and at 25:1 with 110LL, its so dry after 4 weeks that I'm not going to be running it anymore.

Boat oil

 

[jmssaws]

Lucas is better than Benol for a saw. Just about any aircooled oil is better than Benol in a saw.

I would believe that if I didn't know otherwise.

Lucas High Performance Semi-Synthetic 2-Cycle Oil has been specifically developed to give a long trouble-free life to gasoline-powered 2-cycle engines. Designed for any oil injection system or pre mix up to 50:1. Use in Snowmobiles, Weed Eaters, Leaf Blowers, Chain Saws and more

My take is if it is thin enough for oil injectors ,not the best choice for a premix .

 

[Benelli777]

I use Motul 710 (FD rated) in my saws and brushcutters. Yes it is a little thin.

Clean burning so far at 40:1 in my ported saws.

For what it's worth ,i have been milling with saber 40 to 1 ,And even put a stock muffler on the 660 to keep noise down ,when i pull the muffler cover off ,some oil on the piston skirt and the muffler can is sooty except by the exhaust port ,that is a tan color and dry ,the paint has not burned off the muffler cover yet ,am tuned to 13k piss revving it ,depending on load in the cut 7-9k on my tach .When i ran 2r and mobil 1 ,the muffler got hot enough to burn the paint off of it with a stock muffler ,and the cover was dry ,not sooty like the saber ,so i had to run the dual port cover on the front to let heat out ,so at least milling i think the saber runs the saw cooler than the bike oils i used .i was making some hard passes last night on a dry fir log that had been down a year ,was taking a whole tank of fuel per cut and the muffler cover did not burn the paint off .

Ever check cylinder Temps while doing that? I've checked them alot and never had one over 350. All ported with big holes in the muffler though.

 

[jmssaws]

A had a 066 that was very high compression with a big ignition advance that would cook the paint off the muffler in a cut or 2.

All of them I checked were tune on the edge

 

[junkman]

I may check the tool truck see what a infa red heat gun costs ,i need one for work anyways to check the tow trucks exh manifolds to see if firing evenly ,i am impressed i bet i have burned 5-6 gallons with the stock muffler now ,paint is still on the cover ,i threw the dual port cover on last night ,it did pick up some power ,but my ears were ringing after that pass so i put the stock cover back on ,i lost some grunt choking it down for sure ,but when running a saw for 3 hours strait ,i will take the quietness over some power .
The milling 660 is ported for milling also if that matters .

I will take my scope camera home and check the piston top see what the mill saw looks like inside ,try to get some images .

 

[jmssaws]

Dual port covers are loud.

 

[junkman]

I should have threw a couple bottles of Saber in the box for you to try ,get your opinion on it .

I'll send you one of my mufflers.
They flow enough for any saw I've ever built and aren't neer as loud.

 

[mdavlee]

I've seen over 450° on the fins on the exhaust side after a 5' long cut

 

[jmssaws]

Anybody ever tested the difference in heat from a stock saw to a ported one?

I think I know the outcome but never have checked.

I think somewhere Redbull661 had some data on the 661 stock and ported ,the ported with more compresion made more heat .

I need to check one of the new lower compression saws I'm building now,does a mtronic run hotter than a regular saw?

That would be a good test ,m-tronic may be a little hotter ,but who knows till the heat gun comes out .

 

[bwalker]

Its great oil. I like that its almost half the price of K2

You m

I would believe that if I didn't know otherwise.

Strangely, you are the only one in the history of the two cycle motor that has found benol to be perfectly clean.
A guy posted pics of a 361 on this page the other day run on Benol and it looked terrible like I knew it would.
