What oil is best? and what ratio?

[Keith Gandy]

It smells like fish in the bottle

It does have a funny smell in the bottle doesnt it? I havent noticed the smell using my weedeater or saw so far. I know it lubes plenty well

I am extra sensitive to smells that is one helpful tool when roasting our amazing coffee.

U liking the original techniplate?

Can't find anything not to like

ran out of mix today so im running a concoction of different oil ultra mixed with supertech.
seems to work fine smells a little wrong but the 4 mix didn't complain.

Its not unusual for semi synthetics to have a higher JASO rating in a line of oils from a blender just like the Stihl oils. If one judges an oil by smell & irritation to eyes & sinuses, run a quality mineral oil and the issue magically disappears.

For starters there are very few straight minerals oils left. Attributing strong smell to the base oil is flawed too. Often it's the diluent that smells. Back in the day when straight mineral oils were still widely in use some smelled plenty strong.

What mineral oils are left

Most everything I find is semi synthetic

Sent from my non internal combustion device.

I havent seen any in some time, but I am sure there are some out there.

Looks rich. Dry muffler?

 

[porsche965]

So impress us. Take this up to 40:1 and how does she look? Or even 50:1 like a good FD oil suggests. But get out of the extremely safe zones of 32:1.

A boat oil can run at 32:1. All day long.

I like what I see but more carbon tells me more on the crown. Higher ratios will bring more carbon and less "washing." You have more HP left in the saw at this ratio. GO Red Bull!

I'll be trying Shaeffer's at 50:1 soon.

 

[odin]

Thanks for the pics. Lookin' good. Just out of curiosity, Redbull, what B&C setup do you test with?

 

[bwalker]

Saw is running rich.
I am using the same oil in my Lawnboy mower and it doesn't look like this at all.

Thank you, sir. Just started digging into it. Nice thread.

Kinda digging your muffler testing work on the 660 as well. This bit especially so:

this is what I think as well...

baffle in = you get the back pressure. but it holds in too much heat. Interesting thing is... unless you drill in that 1/2" hole where I have it. It's no where near as fast. I started at 1/4" hole and it got way faster and then solid, then I went to 1/2" and it got even faster yet. But only as a tri port. If you have only have the ported front cover and not that extra side port it's not good.


But if you take the baffle out, then I think you gotta get the back pressure from a solid/no port front cover. I kinda confirmed this for myself when I tried putting a opening/port on the 661 front cover...doesn't work out so well.


To me the bi port + solid/no port cover makes the most sense.

back pressure - from the solid/no port front cover

flow - equally placed and equally sized ports/holes. ...and you can go too big. 3/4-7/8" seems to be pretty nice.

screen size - the narrow weave seems to hold in too much heat as the 2nd cuts are always slower. The wide screens the cuts are much more consistent.


NOTE - I personally believe this back pressure thing is uber important only for the long bar. Seems if your doing short bar stuff you almost don't want a muffler at all... Don't quite understand it but these have been my observations.

supertech aircooled is mineral

Saw is running rich.

pennzoil xlf looks to burn the best in my lawn boy but im having a hard time finding it in my area.

I had good luck with the penzoil full synthetic in my LB.

Ran my 1st batch of Red Armor at 40:1 in my Echo Srm225 today. Mixed well, very red when mixed, ran really well, and no noticeable smell

It is good oil. My saws are treated as un- loved tools. They seem to like it.

 

[jake wells]

weather permitting im going to remove the muffler from my most used lawn boy tomorrow and check out the ports and examine how cruddy the muffler is inside.

It smells like fish in the bottle

I've noticed K2 has the same fish smell from the jug.

 

[CR500]

It does smell in the bottle but running I can not smell anything bad
