How Much Oil Can a 12.5 Briggs & Stratton Take?
Briggs & Stratton manufactures little four-cycle gasoline engines in many different horsepower ratings. The engine lineup includes 12.5 horsepower engine versions to be used on riding lawnmowers, garden tractors, engine generators and other outdoor power equipment. The four-cycle design of these 12.5 HP units keeps lubricating oil at a sump separate from the gas system.
When operating your 12.5 HP motor at temperatures above 40 degrees Fahrenheit, Briggs & Stratton requires 48 fluid oz (1.5 quarts) of SAE 30 weight detergent motor oil qualified for four-cycle engine support amounts SF-SJ or greater. When operating at temperatures below 40 degrees Fahrenheit, the company says it is possible to use 48 oz of 10W-30 mineral oil or 5W-30 synthetic petroleum.
