VP C9 here (special order). I used to run 100LL, but C9 has a much better distillation curve/Reed vapor pressure for a 2 cycle. I used Champion WP-2 Semi Synthetic 2t based on a number of reviews on various different sites. It's not really that well known from what I can tell. Give it a shot if you haven't, you can buy it online at various sites. Also have tried Lubegard's oil, I prefer Champion because its a much heavier visc (how much that really matters for my usage I have no idea honestly). Both of these oils have very low odor when burning.

Running 40:1 in a 50:1 world.

I do and run VPracing C9 with VPracing oil 40:1 in a Husky XP576 auto tune no problems whatsoever.Do you have any experience with Husqvarna’s auto tune?
I have a dealer 3 miles away that has just about any fuel in the VP lineup seriously everything on hand. I have been going to her for years she knows what I'm looking for when I walk in amd treats me good I believe last can was 73.00 dollars. I believe few years ago it was about 63.oo per can.VP C9 users, Do you guys have a better source than online? I see VP C9 online for $99 per 5 gallon jug. That’s crazy. I use E0 91 and haven’t had any issues. Last time I got fuel it was ~$4.50 per gallon in the spring.
Just my $0.02

I use e0 regular unleaded pump gas and red armor.

No more pop on the first pull, back to several pulls.Go back to 50 :1 and see what happens.
I second this.Why is it the worst? What are you basing this on?
My John Deere chain saw requires 20-1. ( it's 45 years old ) The mix I do, winds up being 16-1. 8 oz of oil to a gallon of gas. I've have run my Stihl weed whipper ( 40-1 ) for a dozen years or so on the 16-1, runs fine. I've just bought a Husqvarna leaf blower and I'm running that on the 16-1. No issues so far.

Loss of power.I second this.
Loss of rpm.
Slower recovery from a heavy load.
Scorched spark plug.
Clearly runs better on pump gas and redarmor In every way.
Starting or popping on the first pull vs multiple pulls just to get a pop.
And pump gas and redarmor is cheaper.
I have been running 40:1 now for a while with regular ethanol free pump gas and red armor oil.
My echo saws smoke a little bit more if I let them idle for say 20 seconds or more then I get back on the throttle.
Biggest change I noticed is the 60cc echo pops on the first pull most of the time and if I'm quick I can get the 40cc saw to start on the first pull. They never did that with 50:1 and I have had the 40cc echo for 12 years and the 60cc echo for 6 years.
At the start of my forestry career we ran our Homelites and McCullochs* at 16:1. Both engine design/materials and 2 cycle oil have changed tremendously compared to 50 years ago. It seems that your new machines might not benefit running at 16:1? Keep us posted on how that goes.My John Deere chain saw requires 20-1.

I also wonder what are the differences of the old oils at 16:1 compared to modern oils at 16:1. Does running the modern oils at 16:1 cause any problems? Anyone know?

Echo so yeah.My +20 year old Echo leaf blower runs equally well on 40:1 and 50:1. I have never done a single bit of maintenance on the thing and it just keeps running.
What oil are you using?I can't find any information what to run in my Polaris Xplorer 300 2 stroke as it has oil injection. It sat for a few years so the oil pump lost it's prime. I've been running 32:1 in it. The oil pump primed. The smoke is ridiculous and it doesn't like to idle long before fouling the plug. Runs great, though!

Yeah there's a difference. When the new synthetic based thicc oils came out they had to create a whole new test series.At the start of my forestry career we ran our Homelites and McCullochs* at 16:1.

The old test: they run the engines for some amount of time, tear down the engines and compare them.
The old test on the newest generation of 2 stroke oils: they'd run the standard test and there was virtually no wear and no noticeable difference between the other similar new generation oils.
So to test these new synthetic oils with a bit of detergent they doubled the old test time and came out with the FD standard.
So those old 16:1 McCullochs could run 32:1 FD oil and last longer than the old oil running at 16:1. They could probably run 40:1.
That FD oil is thicc so if I run 32:1 in my saw the exhaust port gets oily and it smokes when I come up on the throttle after it's been idling for a bit. 40:1 is just about perfect.
I'll run 32:1 in the weedeater since it's just held wide open for minutes at a time with very little idle time. Very little smoke, no smoke when warm and little to no exhaust pipe oilyness.
Lucas injection oil in the tank. It does seem to go down slowly and supertech TC-W3 around 40:1 in the tank premixed. The manual apparently says TC-W3 is okay.What oil are you using?
Put some echo,belray, golden spectro or my favorite Torco in thereLucas injection oil in the tank. It does seem to go down slowly and supertech TC-W3 around 40:1 in the tank premixed. The manual apparently says TC-W3 is okay.
Everthing I own runs on 40:1 and have been for over a decade. I used to mix my dirtbikes 32:1 and they loved it as long as you were on the throttle. Seemed to make more power. To me 50:1 just isnt enough oil. I have been extremely happy with the vp 40:1 Sef cans, plus it smells good. All equipment did require a mild retune, but that was a simple job for me. Im an old school carburetor man from WAY BACK
Whatever hapoened to the OPTI2 mix? Wasnt that a mix that said it was universal mix for any two stroke? My grandpa ran that stuff in his McColluch saws and string trimmers. I always thought it stunk and smoked a lot
I had a polaris 250 two stroke. It was one model after the original cyclone. That thing ran forever on cheap ol quicksilver boat oil my dad had in the shop. It did smoke quite a bit though but it never fouled the plugI can't find any information what to run in my Polaris Xplorer 300 2 stroke as it has oil injection.
