MERCURY Motor Oils 8M0078630 Editorial Review

The Mercury 4-Stroke Engine Oil is a popular choice for boat engines. While it can be used in other engines, a Yamaha dealer recommends using oil specific to the manufacturer. It is also suggested to check the owner's manual before using it in a 250 pro xs four stroke. The oil meets specifications for boat engines and is recommended by Mercruiser for their engines. It comes in quart sizes and some customers confirm that it is a full synthetic blend. However, one reviewer reported being delivered non-synthetic oil. The product is said to work well and has been used in many marine engines with zero issues. It is also noted that it is the same as Quicksilver oil but cheaper.
