Two-Stroke Oils: All the Same?

Tru-fuel Is not alkylate, it’s literally just 92 octane ethanol free unleaded petrol wjth 2 stroke oil and stabiliser. Motomix and aspen are alkylate fuels, trufuel isn’t.

The TruFuel safety data sheet disagrees with you.

Just give it a sniff, you can tell it's not gasoline.

Ah okk, my apologies, I looked into alkylate fuels quite a few times and never once saw Tru-Fuel’s website mention it! Good to know. I’ll let you know how things pan out tomorrow!

I’d say that the different cans of trufuel was the issue here not the ratio. After all, trufuel is just ethanol free unleaded, it has a shelf life and will age differently depending on when it was made. I’m confident you’d not see that change if you used the same tank of pump gas and just changed the ratio by 1%.

Going super lean for 1% difference in mix doesn’t sound right. It may change the rpm by a very small margin noticable via a tachometer.

I’ll report back tomorrow and happy to admit I’m wrong if I am.

True fuel is not just ethanol free unleaded.

I just can't fathom this. Zero reason to play the "how close to running my engine without oil can I get?" game. It's like going to the desert and trying to live on as little water as possible, or draining 3 quarts of oil out of your car's engine, and driving around on the remaining 2 quarts. More oil seals rings better, makes more power, lubes better, cools better, and good oil even runs cleaner, due to more detergents being present in the greater amount of oil. Just absolutely zero reason to even attempt this.

If I took my equipment to a shop, and they put 100:1 mix in it, harsh words would be spoken, and they would never see a single penny of my money ever again.

Exactly. Only a fool runs 100:1.

@North by Northwest he ran the cheapo blackmax 2 cycle oil at walmart all summer with no problems around here it is 0.96 cents per 2.6 ounce bottle or 7.97 for the 16 ounce squeeze bottle.

Yeah , tried to blow the dam old trimmer up with it . I picked it up in Feb when I was at the I-500 snowmobile race . Actually cleaned up the ports pretty well after a few weeks running it hard . I'am all out , may buy some more next trip to Wally World in Michigan next month during Black powder / Rifle season !

I have run Saber @ 70:1 within a old 90 HP V-4 Evinrude for 10 yrs no issues . However in Air Cooled 50:1 is as lean as I feel comfortable brother !

You should try it in your sled lol.

I believe the Blackmax was $5 for the syn blend & $ 7 for the 100% syn for 16 oz bottles . For use & fishing camp trimming it was satisfactory , even was advertised with a stabilizer additive . It didn't smoke heavy or stink , same price as their Super-tech more or less !

 

[skeet88]

Now I have to go find some more oil. Not an everyday chainsawer like some, mainly running my string trimmer. Be Safe.

Ok ok enough already I am going to pour the Lucas mix in the lawnmower and get something better! Y’all Be Good! All jokes aside this thread has been both educational and entertaining!

You , have a good one Skeet88.

Do you have to retune an engine, if the only variable is changing the mix ratio.

Also wanted to update you guys with Amsoil Saber 32:1. The first time I tested it I did 20 mins loaded by about 1000 rpm below max rpm - no longer 4 stroking, but I suppose, not really what an engine would see under use. I got a heap of carbon.

So, I cleaned the piston and I re did the test, this time I did 60 seconds loaded by 3000 rpm, then 20 seconds idle - a bit more close to real world use. I repeated this for 20 minutes. This is exactly what I had hoped to see! I won’t run it at 32:1 still though, I’ll probably go to 40:1.

I came to an idea...

We dont have "proper 2stroke sparklug(s) colour" thread....

If you "google" that topic.....everyone is describing that propper colour should be "coffe brown"....BUT!

Since 2strokes has evolved (X-torq....2-mix...) and also 2stroke oils have also evolved....many sparkplugs nowadays look like that engine is running (slightly) on a lean side....

That makes me confused while I am reading my sparkplugs in my O.P.E. equipement!

Should we have/get a separate topic/video about that?!

EDIT: **** stands for outdoor power equipement!

I agree, modern oils and fuels don’t seem to give the brown indication they use to!

For reference, the only thing different is the oil used here. Castor = brown, Synthetic = grey.

Heap of carbon? Gah! No Saber for me lol. Actually I've been using Red Armor but I've seen tests similar to your's using Sthil Ultra with same result.
