Frequently Asked Questions
What’s the most important car maintenance to do?
Engine oil changes are the single most important regular maintenance. Running low on oil or using degraded oil causes catastrophic engine damage. After that, wiper blades and bulbs are critical for safety.
How much does basic car maintenance cost per year?
Doing it yourself, expect £80-150 per year for wipers, oil change, cabin filter, and occasional bulbs. At a garage, the same maintenance costs £250-500+.
