Briggs Stratton Engine Oil Recommendations(By Manufacturer)

Selecting the appropriate engine oil for your Briggs & Stratton engine ensures optimal performance, longevity, and reliability.

This post goes into the various oil types suitable for different operating conditions, oil capacities, and best practices for maintaining your engine. Let’s jump in.

Briggs Stratton Engine Oil Recommendations

Briggs & Stratton recommends SAE 30 for warm temperatures, SAE 10W-30 for varying temperatures, Synthetic 5W-30 for all-weather performance, and Vanguard 15W-50 for continuous-use applications.

You can use 5W-30 instead of 10W-30, but 15W-40 and 20W-50 are not recommended as they are too thick for small engines. While 10W-40 can be used, 10W-30 is generally preferred.

The difference between 10W-30 and 10W-40 is that 10W-40 is thicker at high temperatures, which may not be ideal for lawnmowers. Briggs & Stratton engine oil capacity varies, with walk-behind mowers holding 15-18 oz (0.44-0.53 L) and riding mowers holding 48-64 oz (1.42-1.89 L).

The choice of oil should be based on the expected operating temperature:

• SAE 30: Ideal for warmer temperatures above 40°F (5°C). However, using SAE 30 below 40°F can result in hard starting.
• SAE 10W-30: Suitable for varying temperature ranges from 0 to 100°F (-18 to 38°C). This grade improves cold-weather starting but may increase oil consumption at temperatures above 80°F (27°C). Regularly check oil levels when operating in warmer conditions.
• Synthetic SAE 5W-30 provides the best protection at all temperatures, ranging from -20 to 120°F (-30 to 40°C). It improves starting in cold weather and reduces oil consumption.
• Vanguard 15W-50 Synthetic Oil: Recommended for continuous-use applications, such as commercial lawn cutting or pressure washing, especially in temperatures ranging from 20°F to 130°F (-6 to 54°C).

Oil Capacities for Different Engine Types

Understanding your engine’s oil capacity is vital to ensure proper lubrication without overfilling:

• Walk-Behind Mowers: Typically require 15 oz or 18 oz (0.44 L or 0.53 L) of oil. It’s advisable to check the oil level during the season and add oil when necessary. Change the engine oil every 50 hours of operation or annually, whichever comes first.
• Riding Mowers: Generally have an oil capacity of 48 oz or 64 oz (1.42 L or 1.89 L). Similar to walk-behind mowers, the engine oil should be changed every 100 hours of operation or annually.

Can You Use Synthetic Oil in Briggs & Stratton Engines?

Yes, synthetic oils are acceptable for use in all temperature ranges. Briggs & Stratton has updated their engine oil recommendations to include synthetic 5W-30 or 15W-50 oils. The use of synthetic oil does not alter required oil change intervals.

Briggs & Stratton recommends using their own brand of synthetic oil to ensure compliance with warranty requirements.

How to Check and Maintain Oil Levels

Regular maintenance is key to the longevity of your engine. Follow these steps to check your oil level:

1. Park on a Level Surface: Ensure the equipment is on a flat area to get an accurate reading.
2. Remove and Clean the Dipstick: Take out the dipstick and wipe it with a clean rag to ensure an accurate reading.
3. Reinsert the Dipstick: Ensure the teeth on the cap match the grooves on the dipstick tube before reinserting.
4. Check the Oil Level: Remove the dipstick again and observe the oil level. It should be between the full and add marks.
5. Add Oil if Necessary: If the oil level is low, add a few ounces at a time to avoid overfilling. Allow the oil to settle before rechecking the level.

Best Practices for Engine Maintenance

• Regular Oil Checks: Before each use, check the oil level to ensure it’s within the recommended range.
• Scheduled Oil Changes: Adhere to the recommended oil change intervals—every 50 hours or annually for walk-behind mowers, and every 100 hours or annually for riding mowers.
• Use High-Quality Oils: Opt for oils that meet the classifications of “For Service SF, SG, SH, SJ” or higher. Using high-quality detergent oils ensures optimal engine performance.
• Avoid Special Additives: Briggs & Stratton advises against the use of special additives, as they are unnecessary and could potentially harm the engine.

FAQ

What oil is recommended for Briggs and Stratton engine?

Briggs & Stratton recommends using SAE 30 for warm temperatures, SAE 10W-30 for varying temperatures, Synthetic 5W-30 for all-temperature performance, and Vanguard 15W-50 for commercial or continuous-use applications. The oil should meet the classification SF, SG, SH, SJ or higher.

Can I use 5W-30 instead of 10W-30 in my lawn mower?

Yes, you can use 5W-30 instead of 10W-30. Synthetic 5W-30 offers better performance in cold temperatures, providing easier starting and reduced oil consumption.

Can I use 15W-40 instead of 10W-30 in a lawn mower?

15W-40 is generally not recommended for small air-cooled engines like those in lawn mowers. It is a heavier oil commonly used in diesel engines and may cause increased wear or reduced performance in lawn mowers.

Can I use 10W-40 oil in my lawn mower?

While 10W-40 can be used, it is not the preferred choice. It has a higher viscosity at high temperatures, which might not be optimal for small engines. 10W-30 or SAE 30 is usually better suited.

What’s the difference between 10W-30 and 10W-40 engine oil?

The primary difference is in their viscosity at high temperatures. 10W-40 is thicker at high temperatures compared to 10W-30, which may provide better protection in extreme heat but could cause excess friction in smaller engines.

Can I use 20W-50 oil in my lawn mower?

20W-50 is not recommended for lawn mower engines. It is much thicker than necessary and could lead to increased engine wear, overheating, and poor lubrication.
