Two-Cycle Oil Recommendation Chart
AMSOIL “Fabulous Four” 2-Cycle Oils provide second-to-none protection and performance in modern two-cycle equipment.
As the leader in two-cycle oil technology, AMSOIL has performed extensive research in developing a new line of revolutionary, specialized oils called the “Fabulous Four.” AMSOIL INTERCEPTOR Synthetic 2-Cycle Oil (AIT) was the first new oil to be introduced. It is primarily recommended as an injector oil or at a 50:1 mix ratio in carbureted, electronic fuel injected (EFI) and direct fuel injected (DFI) snowmobiles, personal watercraft, motorcycles and ATV’s. Formulated with wax-free premium quality synthetic esters and a specialized additive package, INTERCEPTOR is designed to address the exhaust valve sticking problems associated with certain snowmobile models.
AMSOIL HP Marine Synthetic 2-Cycle Oil (HPI), DOMINATOR Synthetic 2-Cycle Racing Oil (TDR) and Saber Professional (ATP) and Outboard (ATO) Synthetic 100:1 Pre-Mix 2-Cycle Oils complete the Fabulous Four line-up. The application chart below ranks each oil’s performance in common two-cycle applications.
AMSOIL Product | Outboard | Snowmobile, Motorcycle & ATV | Personal Watercraft & Jet Boat | Chainsaw, Lawn – Garden, Utility |
HP Marine TC-W3, API TC (Injection or 50:1 Pre-Mix) | Excellent (4) (5) | Very Good | Very Good | Not recommended |
INTERCEPTOR API TC, JASO FC (Injection or 50:1 Pre-Mix) | Not recommended | Excellent (4) | Excellent (3) (4) | Good |
DOMINATOR API TC, JASO FC (Injection or 50:1 Pre-Mix) | Racing (1) | Racing (2) | Racing (2) | Very Good |
Saber Professional 100:1 Pre-Mix, ISO-L-EGD JASO FC, API TC | Not recommended | Very Good Pre-Mix Only | Very Good Pre-Mix Only (3) | Excellent |
Saber Outboard 100:1 Pre-Mix, TC-W3, API TC | Excellent Pre-Mix Only | Very Good Pre-Mix Only | Very Good Pre-Mix Only | Not recommended |
Even though AMSOIL 2-Cycle Oils have been optimized for specific applications, they are multi-functional and recommended for use in many areas. The chart rates each oil’s performance abilities per application as follows:
Excellent: “The” primary recommendation for the oil. This is the best possible choice for the application. The oil is specifically designed for the operating conditions of the motors in these markets. There is only one “Excellent” recommendation per category.
Very Good: A main recommendation for the oil. Identifies an oil that is very good for the operating conditions of these motors.
Good: A secondary recommendation for an oil. The oil was not specifically designed for these applications, however, the chemistry in the oil is suited to the operating conditions of these motors.
Not Recommended: Identifies applications where the product was not intended for use. “Excellent” rated products offer superior performance.
Notes:
(1) Not recommended for long-term use in outboard motors as a TC-W3 type oil, although excellent as a race oil for short term use where motors are periodically inspected.
(2) Excellent for racing or modified motors. Very good for recreational use.
(3) For applications calling for TC-W3 product, use the recommendations under “Outboards”.
(4) Recommended for all direct fuel injected (DFI), semi-direct injected (SDI), electronic fuel injected (EFI) and carbureted motors.
(5) Includes Mercury®, Optimax®, Johnson® & Evinrude® FICHT® & E-TEC®, Yamaha® HPDI, Nissan® & Tohatsu® TLDI®
