I'm sure Stihl has already tested that. Oh wait, Stihl Ultra IS green.So I can run my saw on bacon grease now?

I was wonder about that, so I Googled a bit and found some info,Two cycle oils dont have VI improvers..
ITwo cycle oils dont have VI improvers..
Bwalker, I was looking up polybutene ( in Echo Red Armor 2 cycke oil ) and other chemically related substances and from what I read it seems that polybutene can indeed be used as a vii. So since it is in Red Armor 2 cycle oil would it not only act as a smoke reducer but also as a viscosity modifier/viscosity index improver?Two cycle oils dont have VI improvers..
I have a question... Since polybutene is widely used as a viscosity index improver as well as a smoke reducer and dispersant is it not performing the role of a viscosity index improver in Echo Red Armor? How does it not perform such a role of vii in 2 cycle oil if part of the composition?Two cycle oils dont have VI improvers..
I don't know if there is another oil on the shelf at the Stihl dealer![]()
@ my dealer there is- several different oils
That bacon grease belongs on toast--delicious!So I can run my saw on bacon grease now?
Poly iso butene is used in almost all modern two cycle oils as a anti scuff additive. Its what replaced Brite stock in the old two cycle oils because it burns very clean. Its not used as a VI improver in 2 cycle oils.I was wonder about that, so I Googled a bit and found some info,
which led me to looking up Echo Red Armor's composition, which showed polybutene. So, I Googled (polybutene viscosity improver) Well, it seems that polybutene can be used as a viscosity improver, which is also known as a viscosity index improver. I rely on you for good information. Your thoughts?

Its not used as a dispersent in two cycle oil. It is used as a clean burning low smoke base oil. And no, its not a viscosity improver because red armor is not a multi grade four cycle oil.I was wonder about that, so I Googled a bit and found some info,

Thanks for your reply!Its not used as a dispersent in two cycle oil. It is used as a clean burning low smoke base oil. And no, its not a viscosity improver because red armor is not a multi grade four cycle oil.
Of course there are different grades and weights of PIB used for different purposes.
PIB is also the product used in bar oil that provides the tachiness. Sometimes called paratach.
Yes, thank-you sir! I'm glad you could answer. Edit starts here. You are a "sir", right? lolPoly iso butene is used in almost all modern two cycle oils as a anti scuff additive. Its what replaced Brite stock in the old two cycle oils because it burns very clean. Its not used as a VI improver in 2 cycle oils.
VI improver are used in multigrade 4 cycle motor oils to provide the span from the low number to the high. If that makes since
In addition, PIB's used in two cycle oils are designed such that the "unzip" cleanly into combustible gasses once they reach a certain temp. Esters do the same sort of thing.Thanks for your reply!
Ben Walker, last I checked.Yes, thank-you sir! I'm glad you could answer. Edit starts here. You are a "sir", right? lol
It’s fb rated.@lilspenny .....to enlighten you....since you are such an Ultra fan(was banned on BITOG in the past....so can not comment there)
Stihl Ultra in UK is still ISO L-EGB.....
Proof: https://www.stihl.co.uk/en/ap/hp-ultra-two-stroke-engine-oil-1467
If it is ISO L-EGB.....then it can not magically be JASO FD.....since JASO &ISO are almost the same standards ...
- Performance standard: JASO-FD, ISO-L-EGB, oil/fuel ratio 1:50
Yep...but it clearly says FD. The other day I checked and it said FB. Can't have it both ways unless a certification is lagging. I commented... asking Stihl about 4 days ago.... crickets.@lilspenny .....to enlighten you....since you are such an Ultra fan(was banned on BITOG in the past....so can not comment there)

So, how did you get banned?It’s fb rated.
There is an HP Super that is FD rated but not available in the US
@Tomos770So, how did you get banned?
