How to Change the Oil in a Yamaha Snowmobile

Explore America's Campgrounds

The operating conditions for a Yamaha snowmobile's engine are quite a bit harsher than those of a normal vehicle. That is why it is especially important to change the oil regularly and keep an eye on the oil gauge. At the very least, you should change the oil after the first 500 miles of use and every 2,500 miles after that. The oil should also be changed out at the beginning of each snowmobiling season.

Items you will need

  • OW-30 motor oil

  • Bucket or oil pan

  • Philips screwdriver

  • Cloth

  • Crescent wrench

Step 1

Park the snowmobile on a level surface. Push the parking brake switch to the left to secure the snowmobile in place.

Step 2

Start the snowmobile and let it run for 10 to 15 minutes before turning it off.

Step 3

Remove the four screws on the right cover. Repeat for the bottom panel and lower cover.

Step 4

Place a bucket or oil pan under the oil tank.

Step 5

Disconnect the oil level gauge coupler from the oil filler cap, and then remove the oil filler cap.

Step 6

Remove the drain bolt on the oil tank with a crescent wrench and allow oil to drain completely.

Step 7

Move the bucket or oil pan so that it is underneath the engine. Loosen the engine oil drain bolt with a crescent wrench and remove. Allow the oil to drain completely.

Step 8

Replace both drain bolts.

Step 9

Add 1.5 liters of OW-30 motor oil to the oil tank. Replace the oil filler cap.

Step 10

Start the engine. Allow the snowmobile to run for a few minutes and then turn it off.

Step 11

Pull the dipstick out of the oil tank and wipe it on a cloth. Reinsert it in the oil tank, then remove to check the oil level.

Step 12

Add oil as necessary to raise the oil level to between the "L" and "H" markers on the dipstick.

Step 13

Reinstall all detached parts.


  • Never fill oil past the "H" mark on the dipstick, as it can damage the engine and cause oil leaks.
