UNOFFICIAL 2-Stroke OIL Brand Specification/Standard Thread

[one.man.band]

There are 3 different 2-stoke oil standard rating systems in use, (that i am aware of). Rating systems rate oil by passing certain tests. The 3 organizations which rate oils are as follows:

API - FC (one rating only)

or

ISO-L EGB (good); ISO-L EGC (better); ISO-L EGD (best)

or

JASO FB (good); JASO FC (better); JASO FD (best)

I cannot gather all the information by myself. If anyone is interested please feel free to contribute. Don't want to make it a comment thread.. but just facts. When thread has exhausted itself, i will summarize the replies on a single post. Goal is to separate hype and BS.

List your pre-mix oil brand of choice... and what Oil Standard Spec. it meets (if any). Also add if it has fuel stabilizer. All info is on oil bottle/jug label. If it's not listed on label, it means has not been tested for whatever reason.

Example: Echo-Powerblend (OLD) w/fuel stabilizer.
Meets: JASO FC (M345) and ISO L-EGB

Example: Craftsman #7136555 w/fuel stabilizer.
Meets: API-TC

I saw an oil that said use for all 2-stroke engines at 16:1 32:1 40:1 50:1 and just mix the bottle with one gallon of gas. does this ring true even with older saws?

 

[TK]

I prefer the usage of 2-stroke/1-cycle oil in the proper ratio.

Cycle (n) A periodically repeated sequence of events

I still believe that a 2-stroke is a 1-cycle, and a 4-stroke is a 2-cycle engine :hmm3grin2orange:

 

[dave_376]

tilenick i just read my bottle of Echo oil and it said mix at 50:1 and it may be used in any 2cycle equipment even if it was rated for a different ratio because of their special formulation. I don't think I would do that unless it was for another Echo product.
PS all my equipment is Echo except for a Jonsered brush cutter

Yes the oil sets the mix. All of my old Echos are marked either 16:1 or 20:1 and i run up to 40:1 in them...Bob

 

[tilenick]

It just seems to me that the saw engine is made the same as it was years ago and they all ought to run at a comparable mix ,if it is a newer oil. I have a couple stihls 50:1 a craftsman 40:1 and 2 poulan 306A's 32:1 and I am tired of the different mix cans and would like to have one tried and tested gas/oil mixthat will work in the saws that I have. But if not, the three or four cans It is.

Echo PowerBlend oil is now certified JASO FD and ISO-L-EGD .

In this case, the cycle is piston starts moving, piston stops moving. It's called a 2 cycle for a reason. In the end, it's merely semantics, and not worth discussing.

 

[dave76]

Was running Tanaka perfect mix one mix 50:1, it's ISO-L-EGD & JASO FC, hey I got for free for while. But I have since switched to Lowes, Husqvarna LS synthetic 50:1, this oil is ISO L-EGD, JASO FD. Let it be known, I did use the Tanaka oil for a few years and never ever had an issue with it mixed at 50:1. Just have to get it through Grainger, Lowes is much more accsessable. I did notice a bit less smell with the synthetic Husky oil. Both have stabilizers in em.

I use Echo Power Blend and the specs :Exceeds ISO-L-EGD and JASO M345/FD requirements, per whats on the bottles that I buy.

 

[w8ye]

I use this stuff at 32:1 in everything gasoline two stroke for years. Doesn't have a rating printed on it?

Anything in the small print on the rear label? If Quaker State is rated I would think Pennzoil would be, too.

 

[Sprintcar]

Whatever Wally world has on sale.

Gary will be along shortly to us what we is doing wrong mixing oils.

 

[w8ye]

The one I use is the bottle in the middle or the 8oz size. It says nothing about rating on the back?

The 16oz bottle on the right talks about being TC

In the last line of the first paragraph, on the middle bottle, it says that the oil "meets API Service Category TC".

 

[w8ye]

You are correct. I see it now that you pointed it out.

Most of my model airplane gasoline engine friends use Red Line

My Chainsaw friends run Stihl Ultra
