The Proper Way to Change Your 0w40 Royal Purple Oil: A DIY Guide

Changing your own oil is one of the most satisfying and cost-effective maintenance tasks a DIYer can perform. When upgrading to 0w40 Royal Purple oil, it’s essential to follow best practices to ensure a clean and effective change. Remember, safety first!

Tools and Supplies You’ll Need:

New 0w40 Royal Purple oil (check your owner’s manual for capacity)
New oil filter (always replace with the oil)
Oil filter wrench
Socket wrench and appropriate socket for drain plug
Drain pan (large enough for your engine’s oil capacity)
Funnel
Shop rags or paper towels
Gloves (nitrile or latex)
Jack and jack stands (if needed for clearance)
Wheel chocks

Step-by-Step Oil Change Process:

1. Pre-Change Prep and Safety First

Park your vehicle on a level surface. Engage the parking brake and place wheel chocks behind the rear wheels. If you need more clearance, carefully lift the front of the vehicle with a jack and secure it with jack stands. Never work under a vehicle supported only by a jack.

Run the engine for a few minutes to warm the oil slightly. Warm oil flows better and carries more contaminants, but don’t make it scalding hot.

2. Draining the Old Oil

Locate the oil drain plug, usually on the bottom of the oil pan. Position your drain pan directly underneath it. Using your socket wrench, carefully loosen and remove the drain plug. Be prepared, as oil will start flowing immediately.

Allow the oil to drain completely. This can take 10-15 minutes. While it’s draining, locate and remove the old oil filter using your oil filter wrench. Be aware that more oil will drain from the filter housing.

3. Installing the New Filter and Oil

Before installing the new oil filter, apply a thin film of new 0w40 Royal Purple oil to the rubber gasket of the new filter. This helps create a good seal. Hand-tighten the new filter until snug, then give it an additional quarter to half-turn with the wrench as recommended by the filter manufacturer.

Replace the drain plug, tightening it to your vehicle’s specified torque. Do not overtighten, as this can strip the threads.

Using a funnel, carefully add the recommended amount of new 0w40 Royal Purple oil to the engine through the oil filler cap. Start with slightly less than the full capacity, then check the dipstick.

4. Final Checks and Clean-up

Once the oil is added, replace the oil filler cap. Start the engine and let it run for a minute or two to circulate the new oil. Check for any leaks around the drain plug and oil filter. Turn off the engine and wait a few minutes for the oil to settle.

Check the oil level again with the dipstick. Add more oil slowly if needed until it reaches the “full” mark. Properly dispose of the old oil and filter at an authorized recycling center. This is a crucial step for eco-friendly 0w40 Royal Purple oil use.
