Two-Stroke Oils: All the Same?

[Goat boy]

Wooh boy, here we go.

Just going to sit back and watch!

Starting an oil thread is like poking a stick in a hornets nest.

 

[Ol' Brian]

For starters you will find that Stihl Ultra is a Jaso FB oil. The highest quality air cooled oils available are Jaso FD. JASO tests these oils in actual test engines BTW. How's that for a start?

FB/FC/FD are not quality ratings. They are specifications. FC and FD are the same lubricity spec as FB. FC and FD are higher levels of detergency. Not higher levels of quality.

Man, that's reaching. Ben's only asserted that the higher spec oils run cleaner. You asked for evidence, we presented it.

Just admit it bro, you got skunked on this one.

Run Stihl oil all you want, none of us actually care what you do with your own equipment.

 

[Ol' Brian]

You guys... so superficial and shallow. LOL!!! If Stihl paid to get Ultra tested and awarded the FD rating with no other changes at all, you'd be lovin' it. And you know it.
Still need to see the proof. You are just hung up on FD and what you think it means. I've read for a long time that Ultra would easily meet FD if Stihl would pay to get it certified.

Ultra seems to be consistently dirtier than many, however most homeowners won’t ever notice.

How many people question the oil the local garage puts in their car. A few will sure, but not many relatively speaking. I think the same can be said with Ultra. The brand is enough for most to think they’re getting a worthy product and trust.

Oil and ratios really become important when you run equipment professionally, but even then, after a couple of jobs you’ve paid the saw back so they’ll just buy another when it quits.. Most good quality saws will last a homeowner 15-20 years at 50:1 with yearly servicing.

As I’ve said before, we have too much money and time on our hands..

Echo and husky can’t afford to introduce products to the us Market that are trash…kinda why going foreign sometimes works out because the politics ….they want to make competitive products…so can totally see echo having good products cuz it better be to have a chance at husky and Sthil

Something to think about regarding the common misconception that "more oil is better".

Anything in gasoline that is NOT gasoline, displaces gasoline. So in other words, the more oil you add, the LEANER you are making the AIR / FUEL mixture. Many a machine has seized from TOO MUCH oil for this reason. Leaner = HEAT, and preignition or detonation ... or BOTH.

Actually they are quality ratings that require a oil pass a series of tests in tests engines. So once again you are wrong.
Increased cleanliness comes from higher quality base oils, which also in most all cases happen to also have higher lubricity.
High cleanliness is a measure of quality as well.
Ultra contains zero detergents as detergent additives are mettalic and ashless oils can't use any mettalics.
You might just tap out know and admit you don't have a clue what your talking about.

No it doesn’t.

Ultra was tested and it made FB.. it would not pass FD because it's ashless... So who ever told you that is full of crap.
And Stihl doesn't produce a single drop of oil so it wouldn't cost them anything other than a little less profit margin on a higher quality product.

That's BS. You have to tune an engine for operating conditions or let Mtronic/Autotune do it for you. A 20 degree swing in temps has a much greater effect on air to fuel ratio than a few percent change in oil content.
Given this your last few sentences are pure garbage.

Echo products are realistically years to decades behind Stihl and Husky as it pertains to saws. Saws are an after thought for Echo in reality.

 

[kellenobrien]

Yeah, you don’t have to worry about me pushing anything. I don’t give two shíts what oil someone else uses. But I’ll try to help them until I realize they don’t want it

Preachhhhh

I like the take on that, but honestly what’s there to be behind on? Didn’t echo make the 2023 review lists for best saws…the top handle and I think a mid range saw

 

[kellenobrien]

Let’s make our own oil and mix…forum fuels lol

 

[Piotr Pakuła]

It's time to write what oil is your favorite

3 screws on the cool carbs. Heat makes a 2 stroke lean, sure. 1/4 turn ccw on that top left one and heat goes away. It’s magic
