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

[Ron660]

You will never realize their advantages on a low stressed application like a saw,even a ported one,but you will deal with their downsides if you use them.
Don't assume that the viscosity of a blended product is uniform. Most are made up of various viscosity fluids.

I'm only evaluating oil data produced by lab testing using standardized methods. Those are factual comparisons between different oils with no variables. The only variables are the different oils.

Think I've finally got er figured out!

- none of this actually matters

- none of the testing done or that will be done or that could be done even matters because of all the variables

- you've posted 200+ times telling us we're stupid and or wrong

Ok I'm not worthy!


all hail bwalker and yami lube 2r!

It matters. And yes it's true your testing sucks and is a waste of time.

They are factual comparisons of the finished viscosity of a blended product. They are not indicative of what happens inside a motor do the various components of said blend.

A picture of a crank doesn't tell you anything. What's the piston and exhaust port look like.

You can kinda see the squish band. I don't have any pictures of the exhaust port. And it's only had a tank through it since I put it back together. So taking a picture now won't tell you anything

I disagree. Testing several timed cuts of an oil against another oil at the same oil mix ratio give you a factual conclusion. If the data is repeatable which the same outcome.

Here's one I just pulled the muffler off of for you. This paticular saw has been tuned to 17,200 running the oil above at 32:1 with a piston that's 26 years old with no air filter

Here's the plug

When comparative photos are posted and experienced AS Members state their saws, top end and lower end, are lasting longer with racing oils I'll take their word.

Here's the piston

 

[bwalker]

Most of them have very little run time on them as they are hobbyists.
And expiereance AS members. I have been here longer than most on this thread and have more expiereance with all kinds of two cycles to boot.

Hard to tell from your pics.

If you can't see the aluminum it's because you're not looking. I'll tear the saw down if I have to. All it does is go fast.

Lol!! Easy Bull!!!

I'd race him for a coke. My cheap Lucas oil 32:1 and my piddly old saw vs whatever he has with his yamihammy astroglide

I just did a compression test it's only blowing 145lbs.

If it's bare metal your either too rich or haven't ran very long.

That saw has had about 3 gallons through it. And it doesn't idle very long and makes 3 cuts at a time. How many saws have you ever heard tuned rich at 17,200?

 

[cuttinties]

Further more to show he has no real information. That saw is tuned to the ragged edge. I built it to blow up and it hasn't done it yet. I'll make a video here after lunch to give you an idea of what I mean by ragged edge.

 

[cuttinties]

A well scavenging 2 stroke will have wash marks on the crown. This saw makes power from scavenging because it's so low compression it has to.

The rpm they tune at is a function of port timing...
