What You CAN Safely Fix Yourself

Here are common car maintenance tasks you can do at home with a basic toolkit:

✅ Oil and Filter Changes

One of the most frequent and manageable tasks. Just make sure you dispose of old oil properly at a recycling centre.

✅ Air Filter Replacement

No tools needed, just pop the hood, remove the filter, and replace with a clean one.

✅ Spark Plug Replacement

Takes around 20-30 minutes. Just be sure you buy the right size and type for your car.

✅ Battery Swaps

Very straightforward, but always disconnect the negative terminal first for safety.

✅ Light Bulbs and Fuses

Headlight or taillight out? You can usually change bulbs and check fuses yourself.

✅ Wiper Blades

Often overlooked, but super easy to do, and makes a big difference during rain.
