The Craftsman R110 is a compact rear-engine riding mower designed for homeowners who need reliable cutting performance in smaller yards and tight spaces. Powered by a Briggs & Stratton single-cylinder engine, the R110 delivers dependable operation, fuel efficiency, and easy maneuverability. However, like any small engine, proper lubrication is critical for maintaining performance and extending engine life.
Using the correct engine oil helps reduce internal friction, improve cooling, protect against engine wear, and prevent sludge buildup. Regular oil changes also play a major role in avoiding costly engine repairs and ensuring smooth operation throughout the mowing season.
Craftsman R110 Oil Type
The recommended oil type for most Craftsman R110 riding mowers is SAE 10W-30 engine oil. This viscosity provides excellent engine protection across a wide range of operating temperatures and is commonly recommended for Briggs & Stratton-powered riding mowers.
For extremely hot weather, some owners use SAE 30 conventional oil, while 5W-30 full synthetic oil can provide improved cold-weather starting and better year-round protection. Briggs & Stratton-approved synthetic oils are also compatible with most R110 engines.
Best Overall Choice: SAE 10W-30 full synthetic oil offers excellent protection against engine wear, heat breakdown, and seasonal temperature changes.
Craftsman R110 Oil Capacity
The Craftsman R110 is equipped with a Briggs & Stratton single-cylinder engine that typically requires approximately 48 ounces (1.5 quarts) of engine oil when completely drained and refilled. Always verify the oil level using the dipstick after refilling.
Important: Overfilling the Craftsman R110 crankcase can cause excessive smoke, poor engine performance, oil contamination, and potential engine damage. Always fill gradually and verify the level with the dipstick.
Craftsman R110 Oil Filter Information
Many Craftsman R110 models use a Briggs & Stratton splash-lubricated engine that does not include a traditional oil filter. Because there is no filter to capture contaminants, regular oil changes become even more important for long-term engine protection.
Maintenance Tip: Since many R110 engines do not use an oil filter, clean oil is the primary defense against engine wear. Do not extend oil change intervals.
