Changing your oil isn’t rocket science — but screw it up, and your engine will let you know. This guide breaks it down the Route 101 way: fast, simple, and done right. From oil types to torque specs, we’ve got you.

Your Harley’s oil is more than just engine lube — it’s protection, performance, and peace of mind. Whether you’re cruising the coast or hitting the high desert, fresh oil is the barrier between freedom and failure. Neglect it, and that legendary V-Twin won’t stay legendary for long. Trust us — we’ve seen what happens when people wait too long. Spoiler alert: it’s ugly and expensive
Most oil changes go sideways because people miss the small stuff. Here’s everything you’ll need, from tools to torque.
🔧 Pro Tip: Synthetic oil lasts longer, but don’t let that fool you into skipping your change. We do our rental oil changes by the book, and you should too.
We’re not just draining oil — we’re extending the life of your Harley. Step by step, here’s how it’s done.
1. Warm It Up
Run the engine 3–5 minutes. Warm oil drains faster and cleaner.
2. Secure the Bike
Level ground. Kickstand down is fine for most Softails, but use a lift if you have one.
3. Drain the Oil
Place your pan. Remove the drain plug (5/8” socket) and let it pour. Take a breath — that’s the old stuff leaving.
4. Replace the Filter
Remove the old filter (brace yourself — it’s messy). Lube the gasket of the new one with a dab of fresh oil. Hand-tighten only — no wrenches here.
5. Reinstall the Plug
New O-ring. Torque it to 14–21 ft-lbs. Don’t strip it, rookie.
6. Add Fresh Oil
Use a funnel. Add about 3 quarts of 20W-50 (check your manual). Don’t guess — use the dipstick.
7. Run & Recheck
Start the bike. Let it run. Shut it off. Check for leaks. Wait a few, check the dipstick again. Top off if needed.
8. Clean Up Like a Pro
Wipe it down. Recycle your oil and filter responsibly — you’re not a savage.
Anyone can pour in oil — few know how to do it right. Here’s what separates the rookies from the road kings.
🔧 Pro Tip: If you're dripping oil in the garage, you’re not wrenching — you’re leaking. Respect the space. Keep it clean.
If you're serious about your bike, start acting like it. Regular oil changes aren't optional — they're foundational.
An oil change isn’t just maintenance — it’s a statement. It says you respect your machine, your ride, and yourself. At Route 101, we treat every oil change like a performance tune-up, because if your bike’s not right, your ride isn’t either.
Take the time. Do it right. And if you're not sure, ask someone who is.
