What oil is best? and what ratio?

Boat oil

Why does boat oil get a bad rap when run in saws?

 

[Mastermind]

I'm kind of glad I ran across this now. I've been running 40:1 (I try to get at least 3.2 oz of oil per gallon of gas) at the advice on this board to keep the heat down on my 395xp when milling, but I'm starting to think the real change was just me finally adjusting the carb to run a bit more rich. I'm not a smart guy, but wouldn't adding more oil to the gas actually make the saw run leaner, if not tuned? I only have one gas can for premix, right now, so I just tuned all my saws to run on the 40:1 mix. Just to be safe I'm also running two cycle oil for racing dirtbikes, but maybe that's not necessary? I'm thinking about changing over to a plant based 2t oil from a local-ish distributor. They sent me a sample, but it's only enough for a 50:1 on a full gallon of gas...

Milling is different.

If I was milling with a chainsaw, I'd be using Belray H1R at 32:1

I read, maybe even here somewhere, that boat motors run cooler and the boat oil doesn't do as well in the hotter conditions of a chainsaw. Sounds like an urban legend, but I've been wrong before.

I thought there was issues with dominator and corrosion/protection issues when sitting? Or was I misinformed?

Is this what you use normally also?

Not an issue. Long story....but trust me here.

No. I use Amsoil Dominator at 40:1.

You used to be a Yamalube 40:1 guy sir.

I found a better oil.

 

[RI Chevy]

Wow. Very good. TY sir.

Has anyone tried Maxima Castor 927?

Has anyone tried Maxima Castor 927?

Yes. Not one of my favorite oils.

 

[SpaceBus]

Yes. Not one of my favorite oils.

That is surprising given the reputation. Are synthetic oils better? I've only used the B&S little bottle with the measuring cup built in, boat 2t oil, and Maxima Super M. Is the only way to see how well they work to take apart the engine? I get that this thread has covered all of that, but it is also nearly 900 pages long.

This thread has been useless. In a private conversation is where the real oil testing has been conducted. And that testing is why I'm absolutely set on the oils and ratios I use.

 

[Maintenance Chief]

Yup , a twenty minute conversation can be a real perception change , agreed.

Twenty minutes? This testing went on for months and months.

Have the results been published in public, perhaps in a closed thread?

 

[Maintenance Chief]

Oh, I meant that alot can be communicated with a conversation or focused topic.
I can see how a thread gets alot of imput but not alot of focus.
Months seems reasonable enough for a definitive answer, I'm sure yourself and others have due diligence that a thread does not.
I take your answers as informed and tested on chainsaw related issues.

Not really.

Just use Amsoil Dominator.
