What makes 4-stroke engine oil special?
4-stroke engines are the workhorses of the lawn and maintenance world, designed to handle the heavy workloads and storage times that come with this kind of work. Unlike 2-stroke engine oil, 4-stroke engine oil circulates within the engine to lubricate and clean internal components without burning off with the fuel. As oil remains in the crankcase, proper 4-stroke oil must withstand the high temperatures, pressures, and long-term use associated with 4-stroke power equipment while still lubricating and protecting the engine's internal parts.
The AMSOIL Difference
Amsoil has designed and formulated our small engine oil to deliver a balance of performance and protection, ensuring your power equipment operates at peak efficiency when needed. Our formulation protects your engine for up to 200 hours of operation while helping extend your engine’s life with rust inhibitors and other additives to help protect and enhance your engine during heavy work periods. When used in combination with regular maintenance, our 100% synthetic small-engine oil will reduce your maintenance costs and keep your equipment operating even during those long 12-plus-hour days.

Frequently Asked Questions
No Dumb Questions, Just Dry Dipsticks
How often do you need to change the engine oil in your 4-stroke power equipment?
For conventional motor oil, you will want to change the oil in your 4-stroke power equipment every 40-50 hours. However, when you choose to use 100% synthetic small engine oil from Amsoil, you can extend that engine change period by 4x to 200 hours. Our oil reduces oil consumption by up to 61% compared to three leading small-engine oils on the market and better protects and enhances your equipment’s performance during heavy work periods.
What kinds of engines does your 4-stroke small engine oil work with?
Our 4-stroke small engine oil has been tested on hundreds of small engines since we first formulated the mix, including models from Toro, Husqvarna, Honda, and Kubota. Our team is constantly testing our engine oil in new engines and making small changes to the formula to improve performance, while ensuring legacy engines continue to receive the same level of protection as before.
Does your motor oil protect from rust build-up within the engine?
Yes, Amsoil uses specialized chemistry to protect against metal-to-metal contact, which can increase the risk of rust buildup. As well, our small engine oil is formulated to be heat-resistant and offers strong oxidation resistance, ensuring your engine does not create the perfect conditions for rust during storage.
