Amsoil 2-cycle oil

[dippschtick]

Found a bottle of Amsoil 2-cycle. Never opened. I'm guessing around 25 years old. Shook it well and mixed with a gallon of premium gas. Just sitting in a box in the garage. Would you run it? Too old?

Edit: Tried to upload an image but it wouldn't take. It's the 100:1 Pre-Mix.

I would not use it on anything important unless you get blessing from Amsoil directly. Oils do degrade and oxidize with time and I can't imagine that your oil is unaffected. If it was 5 years, it might be still okay?

All that aside, I'm sure the formula is much improved today than it was 25 years ago.

Have you or anyone ever used the TruFuel 50:1 Pre-mix?
Comes in the quart container and I wouldn't use that much in a year.
The gallon I mixed up will sit for years before I use it up.
Stihl weed eater and very occasionally a Stihl MS250.

I'd use it. I have tons of old two stroke oil. I use it in all my stuff without issues.

I've been using up decades old 2 cycle oil the past couple of years. No issues.

Ya I have. I'm on 10 acres and the 2 around my house get wacked regularly. I can easily burn through a quart of fuel in a day.

I have found the VP fuel to run much better than the tru-fuel brand.

In reality I prefer to mix my own but I can't get fuel without ethanol added here.

If I had a cheap piece of garbage ope that wasn't worth the cost of the oil I'd use it.

May we see a picture of fron and back label of that oil?
I may give it a try at 40:1 or 50:1 (the least). But not at 100:1 for sure.

Same!

I’m still running Mobil 1 racing 2T from probably 2006.

Yes we dropped TruFuel due to several issues and now use Stihl Motomix exclusively for two-stroke and premix applications.

I'd run it....in my 4-stroke lawnmower.

I would probably not use it. Also if I was gonna use a premix I'd get echo red armor. If one gallon lasts forever that's just a sign you need more 2 stroke equipment.

I found 3 unopened bottles.
Mixed it 50:1.

That doesn't look 25 years old to me but I also have no idea how old it is

I've been racking my brain trying to remember when I bought it.
It's at least 20 years old.

Admittedly chatgpt is wrong all the time but here's what it says

I see the picture. That's not 25 years old. Maybe 15 or less. Shake well and mix well. Send it!

My bad! You're right.
I got my memory mixed up with some gear oil I purchased 20+ years ago.
I just got off an online chat with a Amsoil rep and they stated it to be 14 years old.
Of course they told me not to use it.
