661 Oil Test 32:1 vs 40:1 vs 50:1 ?

[huskihl]

Given Tree Moneky/Scott said he had ran over 1000 gallons of the stuff through his saws. I threw caution to the wind and ran 3 tanks of schaeffers through my 661 yesterday. Smell is probably the least of all the oils I've tried so far. Saw seemed to really like the stuff. I thought it ran really really well. I'm going to run it some more. It's for sure going to be tested against the others.

- I also dropped off my other 661 with scott to get ported for the oil test. So the oil test will be done with a ported 661.

- I decided on doing the test with .404 Stihl RS chains. ...I think the 661 has so much torque that you need to exert more than normal pressure on the bar to get it's max potential out of 3/8ths RS. While the bigger teeth on the .404 offers enough bite for the torque of the 661...so it's normal pressure/self feeding - more consistent...especially a ported 661.

- thinking probably a 28, 30 or 32" bar. I will get the biggest logs I can and noodle the sides off so the tip is exposed and it'll make for long cuts.

- long cuts will be good to show temps and time differences...if any.

I wouldn't fear too much about using it. Here's a pic of an original 1988 jred 625 p&c. Rode hard and put away wet for 20 years. It was run on whatever was cheapest. For the last 7 years that happened to be supertech. There is some carbon on the exhaust port. The rings wore out before the carbon scored anything. The piston crown is just black with no buildup

Hadnt seen many oils that I ran that wouldn't be useable but whatever was ran in that echo 225 I cleaned completely almost closed off the exhaust port

That was a common thing years ago. I had a Yamaha Tri-Zinger three wheeler when I was around 6 years old. A few years ago I pulled it out of my dad's garage and got it running. It seemed sluggish so I pulled the pipe only to find the exhaust port was nearly completely blocked.

How many cord did it cut a year on average?

Cant imagine many oils today would do that but then again this 225 trimmer may have been ran at low rpm too much?

 

[TBrown]

I've been running Mobil 1 mx2t for a while now at 32:1 40:1 and 45:1

I thought the saw ran better on Schaeffers 32:1 than Mobil 1 at any of the above ratios. Don't know what to tell ya.

I'd say it ran better than 800 and H1R but it's been a while since I've used those. Can't wait to do the oil test!!!

I have been using the schaeffers at 32:1 based on Scott's direction since he ported my 361. I like it since it burns clean and doesn't make me feel sick.

It was my dad's. Used for lot clearing in an excavating business. Probably a couple hundred hours a year

I'm not promoting sh!t oils. I think there are too many variables such as cutting style, ethanol in the fuel, ect... to make any blanket statements about which oil is used. I believe more focus should be on tuning and making sure it has oil in it at all

 

[huskihl]

I'm on my last quart of fd rated full synthetic quicksilver. No noticeable smell. Then I'm on to some lucas. My concrete saw hates amsoil. It's got a 10,000 rpm coil in it and nearly impossible to tune. It's going back on the boat oil diet next year and then I'll know if it's the carb or synthetic that it doesn't like.

I just tore down a Redmax blower with more time on it and the rings were fine. You can find cheap aircooled oil too. No sense in using something the mfg doesn't reccomend.

Tuning is importnat as is making sure your air filter.is services on a regular basis.
But so is running the correct type of oil.

Never had a engine not like an oil. Have had some cause tuning issues, which could be easily fixed with a screw driver.

Yea me either. My chainsaws all run fine on this stuff. Might also be the limited coil on the concrete saw. It doesn't give the normal signs of rich or lean. Weird

I'm sticking with my Amsoil Saber and Motul 800 off road , they both run clean at 40:1 and the saws seem to run well too plus I see a nice light film of oil on the piston which is what I want . I don't want any excess , it doesn't help wear nor performance .

There is no way I would run any TCW3 rated oil , it's not formulated for ail cooled so why run it when you have so many choices of proper rated oils out there ?

Exactly! There are many good air cooled oils out there ranging in price from cheap to expensive.

And there are some great oils on the cheaper end.

And there are some great oils on the cheaper end.

This stuff is pretty damn good for under $10 a quart..

I have noticed some of the dirt bike oils slow the power of my hopped up saws ,

I have not noticed that at all and not from like of trying, except with H1R. If an engines running characteristics change with a change in premix it's almost always a tuning issue and not the oil.
Or its all in your head. We have all heard the "I ran "X" oil" in my saw/truck/boat and it feels likes it's making more power and is crisper,idles better,etc. Placebo effect IMO and IME.

How big of saws are you running ? in my small ones i do not notice anything ,just my really hopped up ones ,dumonde tech has made the crispest power so far at 32 to 1 ,i can get decent results with yamalube ,i am running .404 with a 32 inch bar on a 440 hybrid with 230 psi or 660 saw so i can feel the load difference cutting ,with a smaller bar and 3/8 i do not notice much difference like you are saying ,my weedeater i can tell even more in power loss between oils ,it does not idle as good at 32 to 1 vs 50 to 1

My biggest saw currently is a 372xpg.
