DIY Checks You Can Do Every Month as a Used Car Owner
A short, practical monthly checklist that takes minutes and catches small issues before they grow.
3 min read · Updated 14 Oct 2026
Key Takeaways
- Check all four tyres (and the spare) for correct pressure using a simple gauge, and glance over the tread for any uneven wear or embedded objects
- A quick look at engine oil level and colour on the dipstick, coolant level in the reservoir, and windshield washer fluid takes just a couple of minutes and catches low levels before they become a problem
- Walk around the car with headlights, indicators and brake lights on (ask someone to help check brake lights) and check wiper blades for cracking or streaking — small, quick checks that matter for both safety and legal compliance
You do not need mechanical expertise to catch early warning signs — these simple checks take about ten minutes a month.

1. Tyre Pressure and Visual Tread Check
Check all four tyres (and the spare) for correct pressure using a simple gauge, and glance over the tread for any uneven wear or embedded objects.
2. Fluid Levels
A quick look at engine oil level and colour on the dipstick, coolant level in the reservoir, and windshield washer fluid takes just a couple of minutes and catches low levels before they become a problem.
3. Lights and Wipers
Walk around the car with headlights, indicators and brake lights on (ask someone to help check brake lights) and check wiper blades for cracking or streaking — small, quick checks that matter for both safety and legal compliance.
4. Listen and Feel During Your Normal Drive
No special routine needed here — simply stay attentive during your regular drives for any new noise, vibration or change in how the car feels, and note it down rather than dismissing it, even if it seems minor.
Frequently Asked Questions
Do these checks replace the need for professional servicing?
No — they complement scheduled servicing by catching issues between visits, not replacing the deeper checks a professional service includes.
How long does this monthly routine actually take?
Realistically about 10-15 minutes once you are familiar with it.
Is it worth keeping a simple log of these monthly checks?
Yes — a simple note of date and findings builds a useful record over time and can also support your service history for resale.
