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

[bryanr2]

This has got to be the #1 oil thread in AS history!

Always next year bro...

I'd like to go to Kentucky but I'll probably send my saw with someone and stay home.

Some 2T oils are designed for premix...others are not. As for HR1 l would be testing it in the conditions it was designed to be mixed at 50:1. I bet at 50:1 the results would differ considerably. Some oils take well to higher mix ratios, some don't. As there is really no rules as to what can be printed on an oil bottle, marketing has a big part on what oil people run. It almost becomes personal and all practical rationality gets tossed over board. People feel warm and fuzzy inside sleeping better knowing that the most expensive man made perfect oil is mixed in their saw no matter what the cost is or what the saws best interests really are. We also think we are smarter than OEM's getting our ambitions completely mixed up with our capabilities. In my experience OEM's are not as uninformed as we treat them.

And I would not use it either.

Why wouldn't you use Lucas?

I think the difference between the stock 661 and ported 661 may be larger with a not stock chain. I'm not saying that the results aren't valid, just saying that you can't take a stock loop and utilize power to the best ability of a saw. Looks like you had fun

The same would apply to the stock saw. A good chain can make as much or more difference than a good port job.

I've personally seen no issues running the 661 with 32:1. However, I don't recall if I was running H1-R or K2.

I am done with H1-R though. My recommendations will stay almost as they were. Pick your favorite synthetic oil, now maybe a semi synthetic, and run it at 32:1, no less than 40:1.

This thread had been a good eye opener for sure. I actually mixed some K2 at 40:1 Saturday! I got significantly less smoke at startup.

Lucas is a good semi synthetic that runs well at 32:1. Well anyway enough about oil I've got a new landing to make and skidders to move. I'll catch you guys on the flip side.

Excellent post. Well said.

I've said for a long while now.......respect the designers of these engines.......they are not at all clueless.

Yep.....I've gotten 35% gain from a chain......and I'm not a great chain maker.

Real quick before I hit the woods. Why not take these oils and do an evaporation test? Say 50ml of fuel in a glass container and wait for the fuel to evaporate. Then see which ones feel oil like or like molasses. After all many guys leave saws sit for extended periods of time.

 

[KG441c]

Lets see??? Which flavor this morning!!??

 

[porsche965]

Blend away lol.

Starting to look like the back shelf of a bar! I'm getting the same way.

 

[KG441c]

They sent the belray 2t to me by mistake when I ordered the h1r but told me to keep it. Been using it in a br600 blower, shindiawa t270, and a echo 225 at 40to1 with no issues or buildup

 

[porsche965]

I wonder how the BR 600 valves will like that 2Toil? They seem to be really sensitive to oil mixes. I run straight ultra just because of that in the BR 600.

Porsche I rebuilt my 600 and was using ultra and had buildup under the valves. Best thing to do imo on the valved blowers is to run Yamaha Ringfree with your oil

 

[KenJax Tree]

Todays flavor is Maxima Super M with the last few oz. i have of K2 mixed in.....i think it has 60% K2 blended in it anyways.

Your saws r gonna blow today blending oils!!! Lol!! Ive mixed Amsoil and ultra with 0 issues

Ya all the oils I currently dont run in my ported saws get used in the weedtrimmers and blower with Ringfree. I use the most current super duper oil in my ported saws that my tangled mind told me was best today!!!! Lmbo!!!

 

[KG441c]

In another oil thread we had I talked with the Maxima tech and he told me the thicker oils do impede combustion and wasnt what we needed in our saws. I presented the idea the tech had told me on that thread but if I recall correctly I was told several times I was over thinking it?? Lol!! Guess it doesn't hurt to overthink sometimes

 

[porsche965]

Ringfree. Why not?

I just happen to have room for one more bottle on my bench!

 

[Moparmyway]

I do not see performance differences with most oils, I haven't see any between K2 or R50.

I thought the K2 had a different idle .......... couldn't smoothe it out as well as the R50 and the 800 off road, maybe it was just me. I started trying Lucas; seems to run and lube as well as 800, but R50 is still the best looking and running in every application so far ............. the smell can be "too much" sometimes, so that puts 800 off road and Lucas as my top 3.

Call me crazy, but I might just mix R50 and 800 off road 50/50 just to see if it works and if I like it on one of my "beater" 2 stroke motors that sees ethanol.

After this oil thread the more I think the less I know
