Changing your own oil is a rite of passage. It’s messy, it’s satisfying, and it saves you money. Plus, you know exactly what’s going into your engine. No cheap bulk oil, no stripped drain plugs from an impact gun. Just quality work done by you.
What You Need
- Oil (Check your manual for weight and capacity, usually 5W-30 or 15W-40 for diesels)
- Oil Filter
- Drain Pan
- Socket Wrench or Box End Wrench
- Oil Filter Wrench (Trust me, get one)
- Funnel
- Rags (Lots of them)
Step 1: Warm It Up
Start your truck and let it run for 5 minutes. Warm oil flows faster and carries more sludge out with it. Don’t get it piping hot, though, or you’ll burn yourself.
Step 2: Drain the Old Oil
Crawl under (use jack stands if needed!). Locate the drain plug on the oil pan. Place your pan underneath. Loosen the plug with your wrench, then unscrew it by hand. Be ready to pull your hand away fast as the oil shoots out.
Step 3: Change the Filter
While the oil drains, find the filter. Unscrew it. Make sure the old rubber gasket comes off with it! If it sticks to the engine and you screw the new filter on top of it, you will spray oil everywhere when you start the truck. (Ask me how I know.)
Pro Tip: Dip your finger in new oil and rub it on the new filter’s gasket before installing. This ensures a good seal and makes it easier to remove next time.
Step 4: Refill
Reinstall the drain plug. Don’t over-tighten it! Just snug it up. Pour in the new oil using a funnel. Check the level with the dipstick.
Step 5: Check for Leaks
Start the truck. Look underneath immediately. No drips? You’re good. Shut it off, wait a few minutes, and check the dipstick one last time.
