The best way to determine the oil and gas ratio for two-stroke engines is to consult the owner’s manual for the equipment. The owner’s manual tells the user the exact ratio of oil-to-gas for two-stroke engines based on the type of equipment.Continue Reading
Two-stroke engines, also known as two-cycle engines, run on a specific oil-to-gas ratio. Equipment owners must use oil specifically labeled for two-cycle engines. Major retailers and online auto parts stores carry two-cycle engine oil. Synthetic oil works for two-cycle engines as well. Automotive experts recommend to avoid gasoline over 30 days old when adding it to the oil.
The best way to determine if an engine is two-cycle is to look at the cap on the fill port. If the cap reads “fuel/oil,” then the engine is a two-cycle. If the engine contains two fill ports, one for oil and one for gas, then the engine is a four-stroke, or a four-cycle. Briggs and Stratton recommends that for every one gallon of gasoline, consumers should mix 2.6 U.S. ounces of approved two-cycle engine oil. However, consumers must consult their owner’s manual since every type of equipment with two-cycle engines have different oil-to-gas ratios. Two-cycle engines propel lawn mowers, gas-powered weed eaters and snow blowers.Learn more about Vehicles
