So, the new pb5810t blower which has a similar engine to the Stihl 4-mix is on the market and the recommended oil is Echo branded oil or in general an FD rated oil. No vegetable oil or perhaps animal fat concoction like Stihl Ultra? Why not? Not necessary? No valve deposit problem like Stihls when run on oils other than Stihl Ultra? Or is Stihl just blowing FB smoke? Or, is Echo just too cheap to make an updated oil for their old style Shindaiwa engine? Or is any FD oil the answer to Stihl's valve stem deposits, IF they really are an issue, and Stihl is playing hush? Apparently Echo is willing to bet on any FD oil. The pb5810's owner's manual has no mention of "valves".... not even in their recommended maintenance section. Perhaps Echo is trying to hide the fact that the pb5810 has valves and is a 4-stroke very similar to Stihl's 4-mix. Does the pb5810 have a catalytic converter like Echo 2 stroke machines? What's next for Echo? More 4-mix type models? I suppose Stihl jumped the gun over 20 years ago. Or was Stihl just doing their part to protect our air? Or did/does Stihl believe the 4-mix without catalytic converters is a better design than 2 strokes with catalytic converters. Lots of questions.
Echo 4-mix type engines
- Thread starter lilspenny
- Start date
I took a look at the specs, here is what I found:
Approximately 3.0 kW (4.0 HP) at 7,000 RPM
Valve adjustments every 300 hours
Stratified Charge 4 stroke: Separates intake air and fuel mixture for leaner combustion, improving efficiency and reducing fuel consumption by 20-30%. Note: I'm not sure how they do that, but in two stroke chainsaws, they have distinct transfer ports for air and air/fuel.
If it were me, I'd purchase the big boy, Echo 9010 with it's 6.5HP and top of the line 48N of leaf moving powa.

- Air Volume: Up to 700 CFM (cubic feet per minute) for broad coverage.
- Air Speed: Up to 200 MPH for penetrating force against compacted debris.
- Blowing Force: 28.3 N (Newtons)

Get the echo 9010, it will redefine how you blow leaves and it "blows away" any of the competitors by a long shot.
If you use echo red armor in a stihl 4 mix engine, the results will be a clean engine instead of tons of caked on deposits.

Good info there. Interesting that they went with a stratified charge. I read something like "new generation" that Echo said. I was like "Oh snap there's gonna be a meltdown". I'm with you on the 2 cycle with more power. Bad thing about Stihl 4-mix blowers to me is that if you have to replace the cam wheel you have to remove the engine from the fan. But... I've got a 20 year old fs100rx and the cam is in great shape. Not everyone has that good fortune. They already had a recall on the pb5810t. I saw that Husky has a 2 stroke blower even more powerful than the 9010 Echo.
I have this blower. No other blower comes close. 80cc blower! Easily moves sticks, small limbs even bricks.
Husqvarna has one now that supposedly blows more air.
Maybe, maybe not. It is also an 80cc engine and as we know displacement matters. The Husky seems to perform about the same in youtube tests. One guy was able to move a box with a weight in it a touch more distance (he claims 13%) with the Husky in a single test.
In the end, the Husky is $900 and the Echo is $679, both are 80cc and both produce similar real world results.
Yes, and I suppose to each his own, but ease of repairs and smart design matters. I want to give Husky a chance but sometimes I see the way things are made and I can't quite go there. I have a reason for being a 4-mix owner. One was a gift and the other was bought due to a family member working at a Stihl dealership. Otherwise I would probably own a T-262. But, Stihl is good quality in my book because I have a long history of being beyond satisfied. I do like 2 stroke engines, however.
Husky used to do falsely inflated tests like measuring air In the blower housing instead of at the pipe end. Etc.
I have the echo pb 8010 for 5 years now no complaints it moves the whole pile.
It is much louder than my previous. Pb580
Hearing protection a must. Even for short periods.

Wow. I wear protection with my br800 but it's not super loud. Good to know.
The pb580 wasn't too bad you couldn't talk over it, but it didn't really hurt your ears unless you're running it for an hour or two. The 8010 which is twice as strong, literally 4x as loud. I wear noise canceling Bluetooth headset and it's fine.
if these are the same ones shindawia was making before the merger-stay away! these made the stihl 4 mix look reliable. i had 3 of tese none made it tru even one season.
What was their problem? My 4-mix machines have been extremely reliable. I understand that is not the case with everyone and it's a head shaker to me.
I've been a die-hard Echo guy forever... their equipment just works. I have a 15-year-old PB-250LN with over 2000 hours that still runs and starts like on day one. ALL my Echos get Red Armor exclusively. If there are recalls or warranty issues, they don't flinch and stand by the customer. Period. I ran several PB770, but when the 8010 came out I got one ... and sold it after 2 seasons again because it is only better for one thing and one thing only: Blowing massive amounts of leaves, even when wet. No other bloer comes close so far, but that's only 2 weeks a year for me. For EVERYTHING else, the PB770 is better because you can focus the airstream much more accurately and move the debris accurately with force. The massive amounts of air the 8010/9010 put out don't work well when blowing grass clippings, smaller amounts of leaves and other cleanup work because it blows everything apart, left and right and in the air. I still think the PB770 is the best blower any company has ever brought to market. They are dead reliable. Last week I went to the "dark side" and bought a Stihl BR 800 X because it has all the benefits of the PB-770 with noticeably more force and volume. It's like a supercharged PB-770. I like how it works and hope I don't have any problems with it. I will run Saber oil at 64:1 in it (Simple to mix: 4 oz. Saber in 2 gallons of fuel). Many owners have run Stihl 4-mix engines for years with Saber at 80:1 with no problems.
Yeah, I want to run as much oil as my machines can handle without negatives.
