AMSOIL 2-Stroke Oils

We pitted AMSOIL SABER Professional against ECHO Power Blend XTended Life Universal 2-Stroke Oil in lab testing. See how each oil held up.

Product Code: AIOQT-EA

AMSOIL Synthetic 2-Stroke Injector Oil reduces wear and maximizes engine life. Its high lubricity and reliable film strength help protect against piston scuffing and bearing wear.

Product Code: HPMQT-EA

Excellent for Evinrude® E-TEC™ factory-lean setting (replaces Evinrude XD100™ 2-Cycle Oil). Helps prevent deposits, protects against wear, has low smoke, protects against rust and has low aquatic toxicity. Superior performance as an injection oil or at 50:1 pre-mix.

Product Code: AITQT-EA

High-performance 2-stroke oil with an emphasis on exhaust power valves. Contains high levels of detergent additives to prevent valve sticking. Replaces manufacturer-branded oils. Injector use or 50:1 premix. Excellent in snowmobiles, motorcycles, PWC, ATVs and jet boats.

Product Code: TDRQT-EA

Racers can't win what they don’t finish. That’s why AMSOIL formulators built DOMINATOR® 2-Stroke Racing Oil. This complex blend of oils and additives directly addresses the heat, pressure and friction of race-engineered engines. These engines operate on the edge, yet engine reliability is critical. DOMINATOR does an outstanding job protecting high-performance engines. It adds durability that professional racing teams depend on and delivers confidence so engines can be pushed to the limit.

Product Code: ATPPK-EA

SABER Professional eliminates the problems that plague handheld two-stroke equipment using other oils, including hard starting, rough running, power loss and shortened service life.

Product Code: TCCCN-EA

Provides superior protection and performance for enclosed chains and gears found in snowmobiles, ATVs and general equipment. Formulated with extreme-pressure additives, it helps extend chain and gear life through increased wear protection. AMSOIL Synthetic Chaincase & Gear Oil repels water, while also inhibiting rust, oxidation and foam. Its low pour point ensures superior low-temperature starting, reducing drag to deliver maximum power.

Product Code: ABCQT-EA

Tacky formula clings to metal surfaces better than other oils. Delivers unparalleled lubrication and protection. Anti-wear additives extend the life of bar and chain applications. Ideal for chainsaws.



Professional-use string trimmers, mowers, backpack blowers and other equipment can run continuously in hot, wet and dirty conditions for months straight. In these conditions, equipment can wear out seasonally, representing the perfect environment for putting AMSOIL products to the test.

Get the SABER’s edge

Before the 2016 summer landscaping season, we purchased three new STIHL FS56RC string trimmers and gave them to Duluth Lawn Care, based in Duluth, Minn. The company relies on a fleet of professional-use mowers, string trimmers and other equipment to provide fast, high-quality lawn-mowing and other services to its 4,500 clients. Historically, the company accumulates about 600 hours per season on each of its string trimmers prior to replacement.

Typical use included continuous daily operation in high heat; wet, humid conditions; exposure to airborne dirt and other contaminants and the general daily abuse of professional-use equipment. 

Each trimmer accumulated approximately 600 hours – far more time than the average homeowner puts on a trimmer. After the season, we disassembled the trimmers and checked for wear, carbon buildup and other distress. Select results are shown here.


After a full season of severe-service at mixed 100:1, AMSOIL SABER Professional...

  • Prevented piston-ring sticking for maximum power
  • Eliminated carbon deposits in the exhaust port for optimum airflow and power
  • Fought engine wear for reliable operation
  • Reduced oil costs 65%

SABER fights carbon

Heavy carbon build up can be a problem in professional-use equipment. Oils with poor detergency allow carbon to form in the piston ring lands, on the piston crown, in the exhaust port and on the spark arrestor screen. Carbon chokes off airflow through the engine, robbing the engine of power. It also causes the piston rings to stick in their grooves and fail to form a tight seal against the cylinder wall. The engine loses compression, leading to power loss. This adds up to frustrated workers in the field who can’t work as quickly or efficiently as they need to complete jobs on time and up to standards.

As the images show, SABER Professional nearly eliminated carbon deposits to keep Duluth Lawn Care’s STIHL trimmers running strong all season.

Cuts oil costs

Duluth Lawn Care also saved money on total oil cost. Mixing SABER Professional at 100:1 saved them 65% compared to the cost they would have paid had they used the original equipment manufacturer oil at the conventional 50:1 mix ratio.

Given SABER’s excellent performance, we reassembled the trimmers and returned them to Duluth Lawn Care, allowing the company to use its trimmers longer than historically possible with other oils.
