20 oz. if fully drained, 16 oz. will usually be used in an oil change.
Briggs and Stratton made almost exclusively four stroke engines. There is no fuel oil mixture for a four stroke engine. Are you sure you have a two stroke engine by Briggs and Stratto? rhg
4-cycle
The fuel system on a Briggs and Stratton engine works by fuel being gravity feed from the fuel tank. Fuel goes to the carburetor where air and gas the mix, after the air and fuel mix it is feed into the engine where the engine goes through the four strokes.
There is no "gas oil ratio", the 3.5 hp Briggs and Stratton engine is a four-stroke design, oil should NOT be put into the fuel!!!
There no positive way, but you can get an idea from the Model number. It will be five or six digits. The last four describe carb, bearings, starter, etc. The first one or two are the cubic inches of the engine. Current decals are a torque ratings. You can also go to Briggs at the attached link with the model number and see.
The best way to know if an engine is 2-stroke or 4-stroke, is to look for an oil spout. If the engine has an oil spout where oil has to be poured into, it is a 4-stroke. If the engine has no oil spout and the oil has to be added to the fuel, then it is a 2-stroke.
If the engine is four-cycle, the valve seals may be worn, causing a small amount of oil to seep into the piston cylinder or combustion chamber. If it is two-cycle, the oil/fuel mix may have a little too much oil.
54 hp
it has more horsepower and does not waste as much fuel.
The 2006 Mazda3, also known as the Mazda Zoom-3, comes with different engine options that produce varying horsepower. The 2.0-liter inline-four engine generates approximately 148 horsepower, while the 2.3-liter inline-four engine produces around 156 horsepower. The exact horsepower may vary slightly based on the specific model and trim.
The 1978 Ford Mustang 2.3L inline SOHC four-cylinder has 88 horsepower
The horsepower of an engine can vary based on its design and efficiency, but a rough estimate for a 45.7cc engine is typically around 1.5 to 2.5 horsepower. This range can be influenced by factors such as the type of engine (two-stroke vs. four-stroke) and its intended application. For precise horsepower, it's best to consult the manufacturer's specifications.
