Engine oils, grease and lubes

We offers a complete selection of marine engine lubes, boat engine oil and marine grease for inboard, outboard and inboard/outboard motors. Along with 4-stroke oil for inboard and outboard engines, the selection also includes a choice of 2-cycle TC-W3 oils for 2-cycle outboard motors and PWCs. If you, like many of our customers are a do-it-yourselfer, you’ll be happy to know that West Marine also offers a selection of oil change pumps to make changing engine oil easy. And you will also find a slew of funnels, siphons and spouts to ensure that you don’t spill a drop.

4-Stroke Engine Oil

West Marine offers 4-stroke engine oil for gasoline and diesel engines. Choices include non-synthetic, synthetic blends and full-synthetic motor oils. Extremely popular are Chevron’s line of Delo motor oils, Shell ROTELLA® motor oil and Quicksilver, West Marine and Sierra motor oils. Motor oils are offered in a range of viscosities.

2-Cycle Motor Oil

You will find a selection of premium, non-synthetic and synthetic blend TC-W3 2-cycle oil for outboards and PWCs. Special formulations are offered for high-performance DFI outboards. Choices include West Marine, Quicksilver, Sierra and Evin-Johnson brands.

A variety of pumps make changing engine oil or gear lube easy.

If you prefer to change your boat’s engine oil yourself and are tired of busting your knuckles in the confined space under your boat’s engine, we suggest you consider a manual or electric oil change pump. Some models of oil change pumps are designed to extract engine oil out through an engine’s dip stick tube, while others can be plumbed directly to the engine’s oil sump drain hole.

Apart from changing the crankcase oil in your marine engine, the gear oil in the lower unit of outboards and inboard/outboard engines must also be periodically changed. For this, West Marine offers several lower unit manual gear lube pumps to make the process easy.

Oil Filters

West Marine offers spin-on oil filters for use in most makes and models of outboard motors and marine engines. Brands carried include Quicksilver, Sierra, Yamaha and Yanmar.

Protect and extend the life of moving parts with marine grease.

West Marine offers several types of multi-purpose marine grease for lubricating outboard tilt tubes, shift and throttle linkages, trailer bearings and other moving parts. Grease can be purchased in tubes or in cartridges that are designed to fit into grease guns which are also offered.
