2 stroke oil

[Cannon51]

About 10 years ago my boss sold his boat and brought me what looked like a six pack of Texaco 50-1 outboard oil(it said it was for all 2 stroke engines) and I have used it in my saws, weedeaters and blower mixed at 32-1 until now. I used the last of it yesterday. I'm really not looking to start a debate among oil fanatics, but would like to know what most people buy. I'm looking for a 50-1 oil that I can buy in qt bottles at a mart or auto parts if possible.
would be used in
Husky 359
craftsman 3.7 (roper)
Homelite XL-12
Homelite E-Z
Deere 1600 trimmer
Homelite blower

Use an oil made for air cooled ope, not outboard oil. I myself use Stihl ultra.

You want it in quart bottles and not the pre-mix bottles? For my saws, I run McCulloch oil from 15 years ago. Works fine for me when mixes at 32:1 or 40:1. I'm not a 50:1 type of guy......

Brad Penn (refined and package at the old Kendall PA plant). I use it as a snowmobile oil and it comes in quart bottles:

I'm sure there are others out there. Find an oil distributor which supplies local industries, many times you can buy a case and it will be cheaper than at the larger stores.

I tried alco semi syn 2 stroke a while ago and still use it. Has the jaso fd and iso egd ratings and works well. Plus I get it at a little remote gen store/gas station pretty reasonable.

I use Bel-Ray H1-R @ 32:1 in all my saws FWIW.

it's in me SIG

Years ago I ran Pennzoil outboard oil but I think it was mixed at 16:1. I ran Shindaiwa oil for quite awhile but now everything gets Husky oil at 32:1. I also give the mix a splash of Seafoam for flavor.

Who cares what name is on it as long as it's made for "air cooled engines, full synthetic, fullfill's minimum following standard Jaso FD, API TC, ISO-L-EGD". If that is ok your good to go. If you prefer semi synthetic Jaso FC, ISO-L-EGC then go for it. I always think oil is cheap in the long run. I just got a 4 litre(~1.05 gallon) jug, with the top specification, on sale so that should be sufficient for the next few years.

As already mentioned, you do not want to use outboard oil in a chainsaw.

I recommend that you use a full-synthetic oil. Stihl Ultra is usually easy to find and is a very good choice. Baileys full-synthetic is another very good and affordable option.

You're going to see several motorcycle oils mentioned. I use these myself. Those that you will see mentioned are some of the very best oils you can find. They are made from synthetic esters. With the right additives, these oils provide the highest level of protection combined with very clean burning. A few of these are Belray H1R, Maxima K2, Motul 800 2T, and Klotz R50.

Thanks, I should be able to find one of those somewhere close. The reason I wanted qt's is that I don't use a standard ratio. Since I got the Husky I have cut back to 3.5 oz per gallon+1 oz seafoam, afraid 4 oz it might make it run lean. Oil has come a long way from mixing 20-1 in my new '71 Yamaha enduro.

adding more oil will not make it run lean.....as lean/rich is a function of air to fuel, not fuel to oil.

It's true that lean/rich is a ratio of fuel/oxygen...................but adding more oil to the gasoline/oil mix (making it "thicker", not "richer") will indeed change the tune of the engine (making it run leaner). That's because of two things.

-The rich/lean thing is the ratio of burnable fuel/oxygen. More oil (especially a synthetic that may not burn completely or at all) added to the mix reduces the amount of gasoline in a metered quantity of fuel (that's being mixed with the oxygen).

-More oil in the mix makes the fuel more viscus, so it flows slower through the metering jets/orifices. That means less fuel (and therefore gasoline) is mixed with the air/oxygen.

It may be a slight change, but it's noticible. If you change from 50/1 to 25/1 gas/oil ratio, the change is very noticible. I've noticed the change when switching from 50/1 to 32/1 (or going the other way) with motorcycles and saws. The change in fuel mix always required a change in jetting. This has been extensively covered in motorcycle, outboard, and snowmobile racing circles over the last few decades.

Poulan synthetic @ Wal-mart $6 does 6gal. 40-1

 

[blsnelling]

I run 4 oz/gallon in all my saw.

 

[KenJax Tree]

Currently using Amsoil Saber 3.5oz bottle to 1 gallon or 4oz. to 1 gallon if im using Klotz R50

Had always ran the Stihl Ultra. But this last time I bought a quart of Mystic 2 stroke oil. I'm starting to think that with the exception of a few "discount" brands there all about the same. Someone correct me if I'm wrong, but it seems to me that none of the saw makers manufactures make their own oil anyway.

 

[CTYank]

Any name brand 2-stroke full-synthetic spec-d for air-cooled engines. At 50:1. (The bottles with the little 1-gal measuring compartment work great, even if you fill them externally.)

Haven't had the slightest prob with that in 35 years. Some of the 2-strokes are that old and still run great.

Not inclined to change from that.

Why would adding 1 ounce of Seafoam change your fuel mixture?

I put a gallon of gas, whatever stabilizer I using (either 1 oz Seafoam or 1/2 oz Lucas), and 4 ounces of oil for a 32:1 ratio. Never had any issues.....

I don't think it would change the gas/oil mixture ratio but as Eccentric pointed out as the fuel is metered through the jets the engine receives less combustible usable fuel. I guess

Opti 2 at 100:1. Working 8 hours days, 15 years, multiple users. Stihl Ultra is great too.
