Commercial-grade formulation for hot temperature, severe service operation of small engines where routine maintenance is often difficult or infrequent. Use wherever SAE 10W-30 or SAE 30 oil is specified in gasoline or diesel engines, transmissions, hydraulics and chaincases.

PRODUCT DESCRIPTION
AMSOIL Formula 4-Stroke® Small Engine Oil (ASE) is a robust formulation designed for hot-temperature, severe-service operation of small engines where routine maintenance is often difficult or infrequent. It is formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Unlike conventional SAE 30 motor oils, AMSOIL Small Engine Oil has a naturally high viscosity index and does not contain paraffin (wax). It has a -38°F pour point and qualifies for SAE 10W, making it an “all-season,” multi-grade lubricant with a wide operating temperature range. As an SAE 30 weight motor oil, AMSOIL Small Engine Oil provides outstanding protection for hot-operating engines. Formula 4-Stroke Small Engine Oil is a commercial-grade lubricant that helps improve productivity and reduce maintenance costs through superior engine protection.

Resists Heat and Reduces Oil Consumption
AMSOIL engineered Formula 4-Stroke Small Engine Oil to withstand the high temperatures of hard working engines. It effectively resists oxidation and oil vaporization to control oil thickening and reduce oil consumption. AMSOIL Small Engine Oil lasts longer in service than conventional oils and keeps engines clean for peak operating efficiency.

Excellent For Transmission Systems
AMSOIL Formula 4-Stroke Small Engine Oil is a shear stable formulation that contains no friction modifiers. It will not break down during rigorous mechanical activity, making it ideal for hydraulic or hydrostatic systems and chain cases. It is wet clutch compatible and designed to prevent clutch slippage in commercial or recreational transmissions. AMSOIL Formula 4-Stroke® Small Engine Oil protects gears and bearings during high-demand, commercial duty service.

Superior Protection
AMSOIL Formula 4-Stroke Small Engine Oil is formulated with high levels of premium anti-wear and detergent additive technology. It provides severe service protection of pistons, bearings and gears and effectively neutralizes acids from combustion by-products prone to small engines. Anti-rust additives further protect equipment during storage or infrequent use.

Applications and Recommendations
AMSOIL Formula 4-Stroke® Small Engine Oil is recommended for use wherever SAE 10W-30 or SAE 30 oil is specified in gasoline or diesel engines, transmissions, hydraulics and chain cases that require the following:

  • API SL, SJ, SH, SG...(Gasoline)
  • API CD, CF (Diesel)
  • JASO MA/MA2, ISO-L-EMA2 (Wet Clutch)

Engine manufacturers include: Briggs & Stratton, Kohler, Honda, Tecumseh, Robin, Kawasaki, Onan, Kubota, Yanmar, Wisconsin, Power Train, Vanguard and Linamar.

Mixing AMSOIL
AMSOIL Formula 4-Stroke® Small Engine Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

Service Life
AMSOIL Formula 4-Stroke Synthetic Small Engine Oil is a long-life formulation that can last longer than conventional petroleum oils. It provides an extra measure of protection when equipment typically goes longer between oil changes than is recommended by the equipment manufacturer. Due to wide variances in operating conditions and maintenance practices, AMSOIL recommends extending drain intervals when monitored by oil analysis or following the equipment manufacturer-established drain intervals.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS). An MSDS is available via the Internet at www.amsoil.com or upon request at (715) 392-7101. Keep Out of Reach of Children. Don’t pollute. Return used oil to collection centers.

The only oil for my mower!

By

Verified Buyer

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

I bought a new riding mower and wanted the best oil I could find for it. I found the Formula 4 Stroke small engine oil and liked the fact that it was specifically designed for small engines. This year has been very hot and the grass has grown like crazy so the Amsoil has been put to the test and passed with flying colors. This is the only oil I will put in my mowers from now on.

Best warm weather oil for outdoor power equipment

By 

from Marion IL

Verified Buyer

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

We use Formula 4-Stroke in our commercial lawn mowing business...45 deg F to 100 deg F. It is proving a great oil, no consumption, engines still running like new, and the oil still looks fresh at the OCI. At the 10w rating, it will be fine for cool weather mowing. I'd use the 0w40 formula for severe winter OPE use.

Great small engine oil

By 

from Somers, CT

Verified Buyer

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

I use this oil in my 36 inch walk behind mower, the snow blower and a permanent outdoor standby generator. These small engines are still full on the dipstick at their annual oil changes and the oil looks clean. All of this power equipment is now 10 years old and they are still going strong. Thanks for making such a great product for small engines.

Comments about Formula 4-Stroke Synthetic Small Engine Oil:

I use this oil in my walk behind mower & lawn tractor. One change through the season with about 50 hours on the work horse lawn tractor & the oil is still still clean, I almost feel wasteful when I change it.
However, I know better. I've used Amsoil for the last 12 years & have not been disappointed.
