Why You Should Change Your Oil Before Winter, Not in the Spring

Every fall we hear the same question at the counter: "Can't I just change the oil in the spring before I put it back in the water?"

You can. But by then, your engine has already spent four or five months sitting in dirty oil. That's the part most people don't think about.

What's Really in Your Used Oil

After a season of riding, your oil isn't just "older." It's carrying everything your engine produced all summer: combustion byproducts, acids, fuel residue, and moisture. While you're riding, the oil is moving and doing its job. Once the ski or boat is parked for winter, all of that just sits there, resting against the metal surfaces inside your engine.

Over months of storage, those acids and moisture can start to eat at bearings and internal parts. You won't see it happen, and you won't feel it right away. It shows up later as wear you paid for without ever riding.

Fresh Oil Protects While It Sits

When you change the oil before storage, your engine spends the winter coated in clean oil with no acids and no contaminants. It's the simplest thing you can do to make sure the engine you park in October is the same engine you start in May.

It Also Tells Us What's Going On

Draining the oil gives us a look at the health of your engine. Milky or cloudy oil can mean water is getting in somewhere. Metal flakes can point to internal wear. Catching these in the fall gives you all winter to decide on a repair, instead of finding out in May when everyone wants to be on the water and service schedules are full.

Boat Owners: Don't Forget the Lower Unit

For outboards, the lower unit gear oil matters just as much. If water has worked its way past a seal, it collects in the gearcase. When temperatures drop, that water can freeze and expand, and a cracked gearcase is an expensive way to start the season. Changing the gear oil during winterization gets that water out and shows us whether a seal needs attention.

Let Us Handle It

Oil service is part of our winterization process, so it gets done right alongside fuel stabilizing and everything else your ski or boat needs to make it through the winter.

• Jet ski winterization: $175 plus parts

• Boat/outboard winterization: $225 plus parts

We service all jet ski brands and outboard engines (4-stroke only), and we also offer indoor storage and shrink wrapping so your boat or ski is fully taken care of until spring.

Fall is our busiest season, and spots fill up fast. Call us to get on the schedule.
