Boat Engine Lube Buyer’s Guide

Choosing high quality boat engine lube is a wise investment for a boat owner. A relatively low priced-item, engine lube could be mistaken as not being important. In terms of maintaining the good condition of the engine, it is actually a very important item. The wear and tear of a functioning boat engine and the metals rubbing together will inevitable cause damage over time. Engine lube prevents this damage from happening.

Our buying guide reviews the best boat engine lube on the market so you can choose the right lube for your engine. Following are some common features of boat engine lube to look out for when considering which one to purchase.

Amount

Boat engine lube is the type of product which you apply periodically when the need arises. Generally, applying the lube once or twice per year will be enough. This can vary depending on the amount of mileage you will travel on your boat, which may mean you require more regular application. Getting good value by checking the amount of lube you will get for your money is a good idea. A good bottle of engine lube should last you a long time if you purchase a significant amount.

Viscosity

The viscosity of boat engine lube is the measurement of how easily oil pours at specific temperature. The lower the viscosity number is, the thinner the lube. This will result in easier pouring than a boat engine lube which has a high viscosity number; however these lubes are more effective at maintaining strength of film and pressure at higher temperatures.

Compatibility

Boat engine oils are compatible with different engine types. Some will be suited to, for example, applications above 75HP. Other lubes will be compatible specifically with 2-Stroke or 4 Stroke engines, while others will be universal.
