In this guide, I will discuss the different types of oil available for 4-stroke Mercury outboards, and help you choose the right one for your needs. I will also provide tips on how to change your oil and keep your engine running smoothly.

Types of Oil for 4-Stroke Mercury Outboards

There are two main types of oil that are suitable for use in 4-stroke Mercury outboards:

• Conventional oil: This is the most common type of oil used in 4-stroke outboards. It is made from mineral oil and has a relatively low price tag.
• Synthetic oil: Synthetic oil is made from a blend of chemical compounds and has a number of advantages over conventional oil, including better performance, longer life, and better resistance to heat and wear.

Choosing the Right Oil for Your 4-Stroke Mercury Outboard

When choosing an oil for your 4-stroke Mercury outboard, you need to consider a few factors, including:

• The age of your engine: Older engines typically require a thicker oil than newer engines.
• The climate where you use your boat: If you live in a cold climate, you will need an oil that has a lower viscosity rating.
• The type of boating you do: If you do a lot of trolling or fishing, you will need an oil that has good low-temperature performance.

Tips for Changing Your Oil

Changing the oil in your 4-stroke Mercury outboard is a relatively simple task that can be completed in about 30 minutes. Here are a few tips to help you get the job done:

1. Make sure you have the right tools and materials: You will need an oil drain pan, a funnel, a new oil filter, and new oil.
2. Warm up the engine: This will help to drain the oil more easily.
3. Locate the oil drain plug: The oil drain plug is usually located on the bottom of the engine.
4. Place the oil drain pan under the oil drain plug and loosen the plug. Allow the oil to drain completely.
5. Replace the oil drain plug.
6. Locate the oil filter: The oil filter is usually located near the top of the engine.
7. Remove the oil filter: Use a wrench to loosen the oil filter and carefully remove it.
8. Apply a thin coat of new oil to the gasket of the new oil filter.
9. Screw on the new oil filter until it is snug.
10. Add the correct amount of new oil to the engine. The oil level should be between the “full” and “add” marks on the dipstick.
11. Start the engine and let it run for a few minutes. This will circulate the new oil throughout the engine.
12. Check the oil level again and add more oil if necessary.

By following these tips, you can easily change the oil in your 4-stroke Mercury outboard and keep your engine running smoothly for years to come.
