Jaso FB rated? I have no clue what that is. I run it because it burns cleaner. The regular oil is nasty.AFAIK stihl ultra is only jaso FB rated.. unless something changed recently.

The JASO 2-stroke oil classifications are:
- JASO FA: This is the lowest specification that tests lubrication capability, detergency, initial torque, exhaust smoke and exhaust system blocking. This specification has been officially declared obsolete in 2005 although it is still being used.
- JASO FB: This specification is slightly higher than JASO FA and tests the same characteristics. It requires increased lubrication capability, detergency, exhaust smoke and exhaust system blocking. It corresponds with ISO Global Specification EGB.
- JASO FC: This specification requires the same results for the tests of lubrication capability and initial torque as JASO FB but has higher standards for detergency and exhaust smoke and exhaust system blocking. It corresponds with ISO Global Specification EGC.
- JASO FD: This specification has the same standards as JASO FC except for a higher detergency requirement. It corresponds with ISO Global Specification EGD.
You made me go into the kitchen and grab a bottle. It says "Meets JASO FB" on the back of the bottle in bold print.A quick google turned up this mostly informative link to educate you.
What does the JASO oil specification mean?
JASO (Japanese Automotive Standards Organization) is an organization consisting of major vehicle manufacturers in Japan. It was created as the Japanese equivalent to the API (American Petroleum Institute) specifications because those were not suitable for the unique specification needs of modern...www.rymax-lubricants.com
The echo red armor and others are JASO FD.
That’s why I won’t use the Stihl oil or premix - I’ll use it if there’s no other alternative. I’m sold on Husky XP+, SEF and Red Armor. TruFuel has no business in Echo or Stihl gear.AFAIK stihl ultra is only jaso FB rated.. unless something changed recently.
I get cans of vp racing brand fuel for 1 or 1.25 on clearance in the fall... shelf life 5 years... but mostly use the 90 octane ethanol free pump gas with echo red armor.That’s why I won’t use the Stihl oil or premix - I’ll use it if there’s no other alternative.

Yep, 100%. Meanwhile I have customers with these machines that insist on running 40:1 or 32:1 because "more oil must be better".Fixed jet carbs stick to the prescribed mix ratio. More oil = less fuel. Less fuel = leaner mixture. In 2 strokes lean is mean, exhaust side edges of pistons get too hot and melt or centers of pistons get holed. Fuel actually cools pistons.
Been there, done that on multiple 2 stroke big snowmobile engines over the years with lean fuel mixtures running at 8k rpm.
I go to a gas station that lets me pay down to the penny. I calculate the amount to purchase exactly 2.5 gallons so that the pump shuts off at that point. My STIHL equipment are all 4-Mix engines with easy to adjust air/fuel mixture. All I need is the special 4mm nut driver that STIHL provides.Fixed jet carbs stick to the prescribed mix ratio.

I buy one bottle of oil that makes "5 gallons of gas" about once a year. I'm no that worried if it costs a few dollars more.Looking to buy an Echo hand held blower pb-2520 and want to get input on using Red Armor oil for warranty and durability. I already have a Husqvarna/ Redmax 150BT that runs good on Poulan Pro/Husky semi-synth oil , which is ISO-L-EGD and JASO FD certified as Echo requires for warranty. Last I check is was made by Spectrum. I would like to keep one can of premix. Is the Red Armor worth the 50% price premium over the Poulan Pro or any other quality oil?
If that's the one in the grey bottle it's probably best to stay aways from it.AFAIK stihl ultra is only jaso FB rated.. unless something changed recently.
Or you could just read the gallons line and shut off at 2.5gallons no calculation needed.. I calculate the amount to purchase exactly 2.5 gallons so that the pump shuts off at that point.
