Mercury MerCruiser Oil Change Kits FAQ

How do you perform a MerCruiser motor oil change?

Performing needed maintenance in a timely manner on your MerCruiser is the key to its overall longevity and reliability. The procedure isn’t complicated but can get messy if you don’t know what you’re doing. 

1. Loosen your oil filter to help vent the system.
2. Remove your dipstick, insert your oil pump, and once your oil pump is inserted into the dipstick tube, pull the oil out into your oil capture container.
3. Remove the old oil filter the rest of the way.
4. Prep the new filter for installation by applying a light film of oil onto the face seal of the Mercruiser oil filter.
5. Thread the oil filter onto the oil filter mount and hand tighten.
6. Remove your Mercruiser’s fill cap and insert your funnel to prepare to add the new oil.
7. Fill the engine with the recommended oil with the proper quantity of oil—4.5 liters for a 4.5L sterndrive and 4.7 liters for a 6.2L sterndrive. We recommend using Mercury 25W-40 Synthetic Blend Oil; however, you can use Mercury 25W-40 oil.
8. It’s a good idea to run the engine with the proper water supply to check for any leaks and make sure that the proper oil level is maintained.
9. For more detailed information regarding these maintenance steps and to verify any details that may pertain to your specific engine model, please refer to your Mercury Mercruiser owner’s manual.

To avoid a big mess, use one of our MerCruiser service kits to perform a quick and easy MerCruiser oil change.

Can I use automotive engine oil in my MerCruiser 4-stroke outboard engine?

No, you should never use automotive engine oil in your MerCruiser. Your MerCruiser is built to different tolerances and an aquatic environment that typical automotive engines are not designed for, so the oil that is formulated for automobile engines will not work in marine engines. 

Instead, only use motor oil formulated for the specific conditions of marine environments and rated for the specifications of your Mercury Mercruiser.

Are all oil filters the same?

No, not all MerCruiser parts are created equal - and MerCruiser oil filters are no exception. Only OEM MerCruiser oil filters are manufactured specifically to protect MerCruiser engines, using the finest components and construction methods available. This includes using special filter media and metal filter media bases (instead of cardboard), to create oil filters capable of greater durability and filtration. From the quality of the materials used to their high-quality construction, MerCruiser oil filters outperform and out-protect aftermarket marine engine oil filter alternatives.

How can I best maintain optimal performance of my MerCruiser lower unit?

Changing the gear lube of your MerCruiser motor is essential for ensuring its longevity and smooth operation. Having the parts and products on hand makes performing this critical maintenance step a breeze, which is why a MerCruiser marine gear lube kit is a smart and convenient way to keep your MerCruiser motor running smoothly for years to come. Here are a few reasons why you should change your oil:

1. Increased MerCruiser Lifespan - Your MerCruiser engine begins to degrade from the moment it leaves the factory and accelerates through use. This is especially true if your engine is used heavily at high RPMs, is allowed to corrode, experiences improper long-term storage, and owners neglecting regular maintenance intervals.
2. DIY MerCruiser Repairs Save Time and Money - With little effort over a few hours, you can change your MerCruiser oil, replace routine parts, and lube up your engine - all for much less cash and time spent in the local marine mechanic shop.
3. Change Your MerCruiser Lower Unit Oil - Oil and grease are the primary lubricants that keep your outboard in the water and out of the repair shop. PartsVu.com’s MerCruiser marine gear lube kits ensure you have the right kind of oil for your engine at premium quality. 
4. Maintain Regular Outboard Service Intervals - MerCruiser motors require regular maintenance to stay reliable out on the water and avoid breakdowns. This maintenance must occur after 20 hours of service for new engines, then every 100 hours.
5. Convenience - PartsVu.com’s MerCruiser marine gear lube kits have everything you need to perform gear lube changes and help prevent buying the wrong item or compromising on quality. This includes: Mercury brand gear lube, MerCruiser gear lube pump, and MerCruiser lower unit drain gaskets. Choose the kit that matches your particular model for the correct oil and MerCruiser parts to get the job done easily.
