Exactly my point with the oils of the past. The older Grey echos were manufactured in an era of crap oils. Once echo switched back to orange eqeuiment was around the era oils were much better.
Echo SRM-2620T String Trimmer Review

1) I’ll agree that the Stihl Jaso FB oil is mediocre. Any of the FD oils are better. I like Echo and VPRacing and have had good results with both
2) 50:1 is perfect for weed whips and blowers. The engine stays cleaner and I have seen no reliability or durability issues using 50:1.
3) 32:1 or 40:1 , used in a weed whips or blower, causes excess carbon buildup. This carbon breaks off the cylinder head and scores the cylinder and causes low compression. There is no reason at all to run anything but 50:1 in modern yard tools.

I misspoke earlier; I've been running VP Racing 40:1, not TrueFuel. I'll try the 50 next time. It sure runs great, though.

It works very well in my equipment. I have no reason whatsoever to change to a different oil. There's a good chance that their oil is far superior to FB but they don't want to pay the outrageous certification fees.
These aren't your 1980s 20:1 fogging 2 strokes. I have a Stihl that I picked up at the end of the season 5 years ago and love it. The only thing I've replaced is the spark plug and fuel filter.
That ain't right over here. Trufuel runs much smoother in my Echo's than the VP racing fuel. VP is 94 and trufuel is 92,but the truefuel runs much smoother. Go figure.

Why do you hate the high torque model? You're leaving us hanging in suspense.
What's the difference?
Usually starting octane and packaging with 5 gallon metal cans and often available at pumps
Vp from a pump?
The age old question, if previous person filled with regular, how much premium do you actually get?
I and many others will only pump E0 from a dedicated pump for this very reason. In my 2stroke engines I only use VPracing C9 fuel blended with Red Armor or VPracing 2 stroke oil.
I use it for long storage fuel like generators also.

My 2620 non high torque rules. I do run a lot not wide open as I have a ton of chain link fence and the faster you spin the more it eats up line. I’ve ran red armor non ethanol exclusively.
It did require a long block last summer. It wouldn’t hold crankcase vacuum even fully re sealed. What a mess that was. Partially the Echo distributor and the shop. Was without it for 3 months of peak season. Luckily my little Stihl FS38 was still kicking. The farm got out of hand though, too much for the little FS38.
That said, the 2620 is a power monster. I do take it to the farm 2-3 times a season and it’ll get a couple tanks ran through it wide open on those trips. Probably helps keep the cat cleaned out.
I’m probably due for flex shaft re grease at this point. I bought the Stihl gearcase grease that threads into the fill hole but the echo threads don’t match so I just mush it in with a finger.

Right, and the only places that sell 0 ethanol gas in northern ontario are the stations on reserves. And they make sure that you know their gas has zero ethanol. But none within a 40 minute drive.
I may be wrong, but I think 0 ethanol is illegal in California. There are no stations selling it near me, that I do know. It's okay, though, E10 with stabil is just fine. I don't know why so many people are worried. The only real hassle is making sure you use it up within a year or so. In my limited usage, with my small house, it's simpler to just buy a jug of premix from the local hardware store.
The issue with E10 is no doubt the enthanol but what is more important is the other chemicals they use (i forgot them all) to keep the corn alcohol in suspension. Those chemicals that are absent from E0 drys out the carb parts, and at times the crankshaft seals.
4 stroke OPE = use whatever fuel you want.
2 stoke OPE = E0, VP C9, or Sunoco Optima 95. (Thanks to Cujet for the tip on the racing fuels)
There is something else in CA fuel that goes bad quickly. I fled CA 3 years ago, the ethanol damage in carburetors I'm seeing in Indiana is different than what I dealt with in CA. Even treated CA fuel went bad far faster. Ok for daily use, but a month or two storage is about it. For low use machines the canned fuel makes sense.
If buying E-0 from a non stand alone pump, i pump the first gallon or 2 into my truck. Then fill the generator cans and 2cycle cans.

I'll ask you again why you don't like the high torque model? I was considering getting one, but I'm waiting for your reply.
