I premix my gas for my scrambler 400 4x4 and currently I use Polaris blue at 40:1. Im almost out of 2 cylcle oil so im going to switch to Amsoil because I've heard good things about it. I've been thinking about their product Saber Synthetic 100:1 Premix. They recommend it "VERY GOOD" for atv's. I've talked to a dealer and Amsoil's tech support and they said "YES, you can mix this at 100:1 with no problems in your ATV". Is this right? I sure would get alot of premixed gas for the money. At 100:1 mixture, I would get 24 gallons at a cost of $8.00. WOW! Their cheaper priced Interceptor oil would have to be mixed at 50:1 and would cost $14.40 to mix the same 24 gallons. WHAT DO YOU GUYS THINK?

 

amzoils hard to beat

 

ANYONE!! SHOULD I OR SHOULD'NT I???

 

If that's what it says on the bottle, go for it. The company wouldn't risk the thousands of lawsuits if the claim wasn't true.

I can remember when I first saw Golden Spectro 2-stroke oil (back in the mid 80's...yup, i'm an old F' er!), and I couldn't believe that you could mix that tiny 12.3 OZ bottle with 5 GALLONS of GAS!! (comes out to around 55:1 ratio) I thought for sure my motor was going to grenade!!

But I've been using it for about 20 years and never had a problem!

 

I've ran the 100:1 in a trail mod for years with no problems. I'm now running the amsoil 100:1 at 66 to one in my hpd powermaxx engine! You'll have no problems out of this oil!

 

I've used Amsoil products for 3 years now in my bikes and haven't had any troubles at all!! I love this oil. I use it in all my vehicles as well.

 

I just found a good article to answer my own question. Why can AMSOIL Synthetic 100:1 2-Cycle Oil be mixed at 100:1?

Why can AMSOIL Synthetic 100-1 2-Cycle Oil be mixed at 100:1 while other products are mixed at anywhere from 50:1 to 32:1? It's no mystery. The answer has to do with solvents, or in this case a lack of them.

Solvents often comprise as much as 20-30 percent of a conventional pre-mix two-cycle oil. However, AMSOIL 100-1 2-Cycle Oil uses a proprietary ashless formulation that makes use of esters - and no solvents. This technology actually delivers solvency characteristics while improving lubricity.

Since AMSOIL is 100 percent active, it can be mixed at the economical 100:1 rate.

But the high-performance features of AMSOIL Synthetic 100-1 2-Cycle Oil don't stop with the mix ratio:

The unique synthetic formulation used by AMSOIL is clean burning. The lower emissions you can expect are much more in line with what current and pending lubricant standards and environmental regulations demand - not to mention what our environment deserves.

Due to absence of solvents, fire and flash points are dramatically higher. These higher flash and fire points help AMSOIL products resist volatile evaporation and allow a single, non-ash formulation to be used in both water-cooled and air-cooled applications.

AMSOIL products provide enhanced lubricity. This high lubricity, in turn, aids in engine cooling (since much of the heat generated by an engine comes from friction) and promotes faster response, greater efficiency and improved overall performance.

Ashless formulation has been shown effective in water and air cooled applications. AMSOIL Synthetic 100-1 2-Cycle Oil is perfect for both kinds of applications.

The benefits of using AMSOIL Synthetic 100-1 2-Cycle Oil are clear: economical mix ratio, reduced emissions, less engine fouling, cleaner combustion, reduced smoke, greater efficiency, cooler running, lower volatility and improved performance.

 

I was a user of Opti-2 for years until it became scarce locally.
Amsoil was simple to pick up so I switched to the Sabre for my 2 cycle EQUIPMENT.

With that said, I have never had an oil related failure on either oil since I started using them. I like the Opti-2 better... burns cleaner, runs cooler and also includes fuel stabilizer... but hard to find. Not sure what the ratio was, but I'm thinking it works out to 100:1. I switched to Amsoil Sabre when I bought a bunch of new stuff, started at 50:1 but wasn't breaking in and powering up, went to 64:1, and then to 80:1... and I stuck with 80:1 because it's easy... 1 bottle to 5 gallons.

Anyways, I was thinking of doing the block-off and running one of these mixes to eliminate the risk and cut down the smoke. But I wasn't sure it would be OK considering this is a much larger displacement engine and is also liquid cooled. But it sounds like you guys are using the Sabre at 100:1 with no problem.

I'm thinking of finding Opti-2 again and doing the 'universal mix' which I think is 100:1 or starting with one bottle of Sabre to a fill up of 4 gallons... or 64:1, then maybe moving up to 1 bottle to 5 gallons... or 80:1 and have some left over to fill up my blower, trimmer and hedge clippers... lol...

 

I started reading that and it says in a 2-stroke, "every stroke is a power stroke". My @$$ it is. It's a 2-stroke not a friggin' 1-stroke for God's sake. Every <u>other</u> stroke, 1 out of 2, is a power stroke. That's the definition of a 2-stroke engine. If they don't know any better than that, I woldn't trust them with <u>my</u> engine. Haven't they ever heard of an exhaust stroke? It's power, then exhaust, not power, then more power on the return stroke.

Nah, actually they are technically right... and wrong... but it depends on how you think about it.

Every full stroke is started by the plug firing and igniting the charge.
Top dead center to top dead center... one full revolution...
2 strokes do not have an exhaust stroke.

They have a power stroke down... and exhaust exits the port once the piston drops below it.
Then they have a compression stroke up... sucking in and compressing the charge.

Two strokes, one revolution
The plug fires every revolution of the crank.

4 strokes on the other hand do not... they have valves for intake and exhaust.
The power stroke down, compression up to exhaust, vaccum stroke down to suck in the charge, compression stroke up to compress the charge.

Four strokes, two revolutions.
The plug fires every other revolution.


The simple way to think about it is...
Inside a 2 stroke, intake and compression occur on the up stroke.
Fuel charge is drawn in as a result of combustion, down stroke, exhaust... vaccuum.

Then combustion happens, causing the down stroke and exhaust.

Inside a 4 stroke, intake happens on the first down stroke, compression happens on the following up stroke, then combustion happens causing a down stroke, then exhaust happens on the following up stroke.
