No, they are not. Density is mass per unit volume.

Well, no. Density is mass per unit volume. In the SI system mass is expressed in kilograms; density is kilograms/meter³.
I'm going to avoid the argument about whether the pound is a unit of mass or force.

No need to argue about that. It is used for both, which is one of the things causing confusion with English units. For example, viscosity in English units can be expressed as either pounds-mass per foot-hour or pounds-force seconds per square foot. They are not numerically equal. That is probably why most prefer to use cP or mPa-s.
The oil is a no brainer. Get a good oil. Mix per your saws needs. I do not beeelieve the charlatans on oil. I do not take snake-oil. I have been known to pull a cork. I have gone to the hospital from a chainsaw bite. That might be a good thread. Back on oil. Now people can get set it their ways. I know a 83 year old Snomobile Champion that will only run one gas, one oil, and a splash of snake oil in his saws. Doubt with a 45 in his mouth he would change his recipe.
Did I really need a /sarc on that post? I guess I did. Lighten up people
No disagreement here, but it's not hard to find folks who argue the pound is strictly a unit of force, but nevertheless don't insist on buying their potatoes by the slug.

Would you happen to be an engineer? The use of a slug as a unit of mass is rather obscure, as is the use of a poundal as a unit of force. Both are ways to avoid the use of g-sub-c as a units correction in equations of motion, and I have never seen either used except in engineering courses.

Actually, if you simply look up on Google you will find mass and density are not the same. Either way have a good day.
The best 2 stroke oil.... is the one you remember to add to your fuel.
Actually it's Echo Red Armor.
Case closed, lock the thread.

I have a Husky 41 I straight gassed that approves of this post

I've run 16:1 on accident, after double dosing my usual 32:1 mix. Colorless oil and couldn't remember if I'd added oil already. 16:1 is a lot better than 128:0.

My first chainsaw used 16:1 as standard. It gave me a headache to breathe all those oil fumes.
The wildland fire services have only changed the 2 stroke Mark 3 pumps to 50:1 over the last couple of years. I like that in a pinch, I can run one on my saw mix now. In the past it was 20:1, a quart of the cheapest oil they could find in 5 gallons. Again, we would run them with a spare quart of motor oil if that's all we could find. Initially, it was supposed to be 16:1, then over time, full Jerrys for a quart.
Of course, the Red Armor I run is probably too nice for those things...
No changes in the pumps, just research showing no increased wear.

I have a quart of Amsoil Interceptor that I'm trying to use up in my dirtbike, good stuff but no dye at all, it looks like straight gas after I mixed it.... Causes me anxiety.
Injector oils are quite often clear . A buddy of mine often added an ounce of Sabre to his 50:1 mix to give the fuel coluration lol.
just the difference between 30wt engine oil and an actual 2 stroke oil. No real need for 16 to 1 anymore.
Absolutely.
It's amazing how long those beasts will run on straight gas, they are tough. And I have seen them run on straight gas, get shut down and restart with mix after they cool.

Noun vs verb is not taught in engineering school, apparently.
Schaeffer's two stroke oil. Series 9000 is the full synthetic. Burns clean, protects excellent!! 3OZ/per gallon. That will give you exactly a 42.7:1 mix. I have three ounces bottles so I mix five at a time. The exact measurement given because you need to know! Have a good one !
