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

[bwalker]

Stihl HP Ultra is JASO-FB. The lowest certification on JASO ratings.

If that's true that's scarry...

 

[maulhead]

The one video was labeled wrong I believe. Should all be fixed now.

Andy's 064 was one, Matt's 064, then my Mastermind 460, and Jrsdws Treemonkey 460. Those 064's are fast..

Wish we did this test before I bought this. LOL. Arrived at my door today

I may have to run a few tests of my own now..

Nice saw, and congrats!!

For what is is worth, IMO only,,

661's are for big wood. They were not made for cookie cutting at a GTG, in 24" Oak against a 460.

The 661's are not speed saws for that small wood, they are torque saws for big wood.

The 661 are made for wood like this big 50 something inch piece of Elm, that is what they live for, and this is were they will leave a 460 in the saw chips...



get ya a 36" bar, and go after that big ash you were telling me about

Its true. Myself and ron660 researched oils a yr and a half ago and found ultra to be fb

I can't run mine hard enough in wood like that. The 661s with the Mtronic system love Goonies! Great saw right out of the box. Great value at $1075 in Ohio with a 20"bar.

I agree whole heartedly. . And that ash tree doesn't stand a chance!

Nice to meet you. We both came from 10 + hrs away to meet. I hope you enjoy that 461! It's a good saw.

Mike have u used one of the 54 big bores on a 181 se?

Nope. I like the 52mm bore myself.

 

[mdavlee]

Wouldn't the best test be to make 3 cuts in a row and kill the saw in the end of the 3rd cut and pull the muffler and see how much oil is there? Small impact would get the muffler off in 90 seconds or so tops

I have used h1r oil for years, mostly at 50/1. What I have used it in is 50cc, 80cc,106cc and150cc engines, these engines are mfg by 3w in Germany all for radio controll aircraft. They run at 6000 rpm in summer heat. My exsperience has been almost o carbine buildup and lots of lube on internal parts. It's the only oil I will use in all my 2 strokes

It was great meeting you as well & thanks for the saw! Very happy with it, I can see sending my 441 to a foster home now Got home last night and after I unpacked the truck and shower'd, I stood outside and fired up the 461, just to listen to it, and smiled ear to ear, what a great saw!!

Did you see the results, of the 441 vs 461, 28" bar, same chain & same wood, 31.9 to 22.9

Even Redbull ran the 461 and smiled and said, it makes me want it back now, I bet LOL

Here's an interesting quote from that article...the opposite of what's been said on the forum here.

"One of the things you should do, is run high octane gas with any two-stroke mix. When all of the two strokes (the old days) were developed, they all used Castrol petroleum oil at a 20:1 ratio and found that 92 octane gas had the octane reduced to 72 with presence of that much oil. Modern oils won’t affect the fuel quite as much, but if you started with 86 or 87 octane regular fuel, you can see where you’ll end with a very low octane mix. "

 

[nitehawk55]

^^ that is correct .

Hell , some should try mixing the 30 grade motor oil at 16:1...hahaha !

Is that a ported 461? They are strong saws. Little brother to the 661.

I quoted that exact article 2x in this thread already and seems no one got much from it? Bwalker said the article was pretty much hogwash

yes both the 461 & 441 in that test are ported by MM. I love my 441, a lot! I just got the 461 at the GTG over the weekend and ran a tank threw it. What a saw The 461 was not tuned as high as the 460 were, otherwise it might have pulled a faster time.

Best Octane I can find in non-ethanol around here is 90. For 3.59 a gallon. Bought 21.7 gallons today. That represents a lot of fun!

I'm in the same camp with a ported 441cr. And the Snelled 461 is amazing. Twists 4 stroking north of 15k and loads of torque. Almost a freak of a 461r and it's still getting broke in. 42.6:1 If I didn't like my 661 so well I'd run the two with 28" bars and I think the 461 would have the 661.

The 441c was one of the first 441c saws sold in the U.S. Picked it up 1/28/11. Ported shortly later.

If my Ex would have been as trouble free and happy to work as this 441 saw I'd still be married to her lol.

I don't think I buy that octane reduction theory..at least not with modern oils.

Its not complete garbage but it's pretty dated and I don't buy the octane being reduced at all with modern oils.
