Oil change

Equipment / Supplies

4 quarts of oil (15W-40, diesel oil
- Shell Rotella T4
- Delo 400 LE
Oil Filter (Universal part #300209)
Oil Extractor and tubes
Filter wrench
Rag, paper towels, or shop towels
Oil-absorbent pads
Quart-sized freezer bag
Two kitchen garbage bags
- One will store the extractor tubes when you are done
- The other will be used for all of the discarded items
One large garbage bag
- This will be used to store the extractor when you are done

Set up the extractor per directions
Warm up the engine5-10 minutes
- Just long enough to warm oil, but not to full temp.

Place oil pads under the extractor and the end of the oil-change hose
Remove the cap from oil-change hose, and insert the extractor tube as far down the oil-change hose as possible
Pump extractor slowly. Oil should start to flow. Ideally you pump enough to create a vacuum, then let it slowly suck the oil out. If the flow slows down or stops, pump some more. On mine, the tube was too small for the heavy oil, so I had to pump continuously to get oil to flow.
Once you hear air sucking (listen at the end of the oil-change hose where the tube goes in), pump a couple more times to get as much oil as possible.
Carefully remove the extractor tube and hold the end high to allow the remaining oil to drain into the extractor.
Put a small garbage bag around the extractor tube, and remove it from the extractor.
Replace the cap on the oil change hose, and place the hose back in a safe location.
Remove the extractor and tube from the boat, so you don’t accidentally knock it over later.

Place an oil pad under the filter.
Use a filter wrench or filter pliers to loosen the filter
- Only turn a fraction of a turn, just enough to loosen. You don’t want oil to come out yet.
Get a quart-sized freezer bag, and fold the top back an inch.
- This will keep the ziplock clean so you can seal it when done.
Place the bag over the filter
Turn filter and bag by hand, while keeping the bag pushed up close to the engine to catch as much of the dripping oil as possible.
Seal up bag with filter inside, and place in garbage bag

Make sure old rubber seal is not stuck on the engine
Get a small amount of oil on your finger, and smear it around the rubber seal on the new filter.
Screw the new filter on and tighten by hand only. Do not use a wrench to tighten.

Add oil via the filler cap on the top of the engine.
- Over fill slightly to compensate for oil that will fill the filter

Start the engine
- Shut down if no oil pressure within a few seconds
Run for a couple of minutes
Stop the engine
- Check oil level and add if needed
- Note oil level for comparison at the next oil level check.
  - This will help you learn if you are losing/burning oil
