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

[redbull660]

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.

Down visiting with Scott Kunz (Tree Monkey). This is the stuff he likes to use. Scott is a pretty smart dude, so adding it to the test list. Says he only uses this stuff and mixes at 32:1. Performs great. Plus he sells it for about $8 a qt.

Its a boat oil.

Mr arm wouldn't run full throttle on h1r. K2 it's fine.

I also switched from H1R to K2 with better results/performance/starting. I don't do cookies or production but my saws, trimmer, and blower like it. I didn't choose it because it is the best (we will never know) but because after reading this entire thread I don't recall any negative comments on K2, 32:1.

Have been very happy with K2 and have burned alot of it this year. The only problem is its ridiculously expensive IMO.

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 fully understand that price is a concern for production or high volume users. I am neither and yes it is near the top in the cost category.

Whoever started the fad back when on H1R @ 32:1 anyway?

"Ran better" is pretty subjective. Personally once a specific fuel/oil mix is tuned to the engine I haven't seen much differance in any of them, accept H1R. Everything I have tried ran well, except the above mentioned.
What I care about is long term deposit control and wear. Two items which go hand in hand.

I ran H1R for awhile with no issues at 32:1.

The H1R did have a transparent brown looking film it left behind though and I didnt care for that

I left for a few years and when I return everyone was running that crap...

If I was just using it in saws I wouldn't worry about it, but I am also running it in bikes where you can easily go thought 10 or more gallons a weekend.

Issues with oil typically are cumlative and occur over time, which is one thing this test can't determine. H1R will tune weird right off the bat. At least it has for me.

I always noticed that transparent brown coating from the top ring around top edge of piston and on the top

I ran yamalube r2 and Honda hp2 in all my 2 stroke race bikes with no issues

Both are great oils, I just found the smell of HP2 nasty.

The other thing is with strato engines being more problem running quality oil is more important that ever. They use much less oil and the pistons run very hot.

I've been using HP2 for a while now and don't really notice the smell. It does stink in the bottle but when its burning i don't really notice it much.

Different smellers for different feller i suppose[emoji1]

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

The formulation could have been change too. I haven't smelt it in awhile.
