      Marine Oil

      In order to keep your marine engine running and avoiding costly repairs, it is important to change out your boat oil during your routine maintenance. Just like your car engine needs oil, your boat engine requires oil. However, marine oil typically has extra additives that help protect the engine from corrosion, moisture, and oxidation that can develop from harsh marine conditions. Wholesale Marine knows how important it is to have high-quality boat oil, which is why they only carry the top brands like Quicksilver, Mercury, and Sierra.

      Marine Oil for All Types Of Engines

      For top engine performance, it is important to change your marine oil annually or after every 100 hours of use. So having quality oil on hand will make your job easier when the time comes. Make sure when you are selecting the right oil, you know what type of engine you have and what type of boat oil is best. There are 2-Stroke and 4-Stroke oils.

      Just as with our automotive counterparts, when shopping for marine oil, you should know that there are conventional and synthetic oils available, and whatever your boat requires, Wholesale Marine stocks both. For high-output outboards and inboards, the Quicksilver 25W-40 is a top choice for conventional marine engine oils. If you're shopping for the popular synthetic oil, Sierra’s 25W-40 Synthetic Blend Boat Oil is an excellent choice. This marine oil’s synthetic blend is formulated with antioxidants, anti-wear, and corrosion protection properties.

      When it is time for your routine maintenance on your boat, be sure to shop at Wholesale Marine. We carry a huge inventory of boat oils and lubricants needed to ensure that your engine remains at its optimal performance level. If you have questions about which marine oil is right for your engine, call our boat experts at 877-388-2628 Monday through Friday from 9:00 AM until 6:00 PM EST. We offer same day, flat rate shipping on most items.
