AMSOIL Dominator VS Interceptor VS Saber: Which is Best for What?

Wondering which AMSOIL 2-stroke oil is the best for your particular application? In this article, we'll lay out the differences between AMSOIL Dominator, Interceptor, and Saber so you know which one to buy.

Dominator vs. Interceptor vs. Saber vs. Injector Oil

Before getting into the technical details and performance tests, let's compare prices. To get a more accurate comparison, we've included the price of each 2-stroke oil per quart and per 10 gallons of mixed gas, according to the recommended mix ratios. Please note, if you run any of these products at a different mix ratio, the price comparison per gallon of gas mixed won't be accurate.

AMSOIL 2-Stroke Oil Prices

AMSOIL Product	Mix Ratio	Price Range	Cost Range per 10 Gal Mixed
DOMINATOR®️	50:1
INTERCEPTOR®️	50:1
SABER®️	100:1
2-Stroke Injector Oil	50:1

From the above table, the cheapest AMSOIL 2-stroke oil available by far between Dominator, Interceptor, Saber & Injector Oil is AMSOIL Saber, largely due to the larger mix ratio that is recommended. I've heard of many people running AMSOIL Saber at 70:1 to improve detergency, at that ratio the cost per 10 gallons of mixed gas jumps a couple of dollars but is still cheaper than the rest.

Comparing Technical Specs

Let's compare the technical oil specs provided by AMSOIL for each 2-stroke oil product:

1. Viscosity:

• At 100°C: Saber (14.0) > Dominator (7.0) > Injector (6.6) > Interceptor (6.5)
• At 40°C: Saber (107.4) > Injector (32.9) > Dominator (35.2) > Interceptor (30.7)

Saber has significantly higher viscosity, especially at lower temperatures, which suggests it provides better protection in high-temperature applications.

2. Viscosity Index: Interceptor (172) > Dominator (166) > Injector (156) > Saber (132)

Interceptor has the highest viscosity index, indicating it maintains its viscosity best across temperature changes.

3. Pour Point: Saber (-40°C) > Interceptor (-53°C) > Dominator (-54°C) > Injector (-60°C)

Injector oil and Interceptor have lower pour points, suggesting better cold-weather performance.

4. Flash Point and Fire Point: Saber (180°C/240°C) > Interceptor (102°C) > Dominator (94°C) > Injector (86°C)

Saber has significantly higher flash and fire points, indicating better high-temperature stability and reduced volatility.

5. Additional Tests:

• Interceptor and Injector Oil pass the SAE J1536 Arctic Climate test, suggesting excellent cold-weather performance.
• Interceptor passes the Engine Lubricity Test at a 150:1 mix ratio, indicating exceptional lubrication properties even at very lean mixtures.

Conclusions:

1. Interceptor: Best all-around oil with excellent cold-weather performance, high viscosity index, and exceptional lubrication at lean mixtures. Ideal for high-performance snowmobiles and varied temperature conditions.
2. Dominator: Designed for racing applications with good viscosity at high temperatures. Its properties suggest it's best for high-stress, high-temperature environments.
3. Saber: Highest viscosity and flash/fire points indicate it's designed for extreme high-temperature applications. May be best for commercial equipment or very high-stress environments.
4. Injector Oil: Good all-around performance with excellent cold-weather properties. Suitable for general-purpose use in various 2-stroke engines, especially in colder climates.

Each oil has its strengths, and the choice depends on the specific application, operating conditions, your budget, and equipment requirements.
