I believe a straight 30 weight oil will suffice.
SAE 30
For a Briggs & Stratton Intek engine "PH8170"
48 oz oil capacity
Intek Pro, Vanguard, and I/C engines are for heavier duty Industrial/Commercial applications. The cylinder has a cast-iron sleeve insert. Standard Intek and Powerbuilt have an aluminum cylinder wall. These are for general and consumer use. Diamond refers to a Diamond Bore cylinder, a special preparation of the cylinder for better wear and oil consumption.
I recommend you use SAE 10W30 100% synthetic in any air cooled small engine. Any major brand is fine.
For a 22 hp Briggs & Stratton Intek engine, it is typically recommended to use SAE 30 weight oil for warmer temperatures or SAE 10W-30 for a wider range of temperatures, including colder conditions. Always refer to the owner’s manual for specific oil recommendations based on the engine's usage and environmental conditions. Ensure the oil meets API service classification requirements for optimal performance.
The Toro Intek 465cc engine typically requires about 1.5 quarts of oil for a complete fill. It's always best to check the owner's manual for the specific model to confirm the exact oil capacity and recommended oil type.
Most single cylinder Briggs engines hold 40 oz of oil. SAE-30 type oil
A Briggs and Stratton 17.5 horsepower engine can use any type of small engine motor oil. A heavy duty motor oil is recommended.
Assuming it is a Briggs & Stratton GenTec Pro Intek V-Twin & ELS it will take 60 ounces + 4 more ounces if you also change the filter.
