DIY Oil Change on Mazda CX-30: Step-by-Step Guide

TLDR; The video demonstrates a DIY oil change on a Mazda CX-30, including preparatory steps, draining oil, removing and installing a new filter, and resetting the oil life indicator.

⚙️ Preparatory steps

The preparatory steps involve warming up the engine oil by taking a quick drive to facilitate easier draining.

The necessary tools and items for the oil change include ramps, jack stands, oil collection tub, safety glasses, gloves, oil filter removal tool, zero w20 oil, funnel, degreaser, and paper towels.

The car is driven onto the ramps to access the oil filter and drain plug, which are conveniently positioned for easy access during the oil change.

Care is taken to loosen the drain plug slowly and move the collection pan to catch the oil as it drains out.

🔧 Drain oil

The oil draining process involves loosening the cap at the top, preventing dirt from entering but allowing air in as the oil drains out.

The drain plug is carefully removed, and the oil is allowed to drain fully while ensuring the collection tub catches any splatters.

🔄 Remove filter

The oil filter, tightly installed by Mazda, is removed, and caution is exercised due to the hot oil contained in it.

After discovering that the wrong filter was purchased, a spare filter intended for the Miata is found to be the correct size for the CX-30.

The new filter is prepped with a little fresh oil before being installed and hand-tightened.

🔍 Check & prep new filter

The new oil filter is checked to ensure it matches the old one, and a small amount of fresh oil is applied to the gasket for a smooth seal.

Surprisingly, the wrong filter was purchased, but a spare intended for the Miata is found to be the correct size for the CX-30.

⛽ Install filter & drain plug

The new oil filter is hand-tightened to avoid future difficulties in removal, and the drain plug is carefully reinstalled without over-torquing it.

🚗 Add initial oil

After cleaning the workspace, 4.5 quarts of fresh oil are added, with a final check to ensure the oil level is within the safe range.

The engine is run briefly to circulate the oil, and the oil level is rechecked to ensure it's at the right level.

🔊 Take car off ramps; top up oil

The car is taken off the ramps, and the oil level is checked again to ensure it's at the right level before topping it up if necessary.

The oil level is checked on level ground, and the oil life message is reset to complete the oil change process.

🔄 Reset oil life

The service due soon message is reset to complete the oil change process, and the used oil is recycled at a proper recycling center.
