When to Change More Frequently
Consider shorter intervals if:
- You mainly drive short journeys (under 10 miles) — the oil never fully warms up
- You do lots of stop-start urban driving
- You tow a trailer or caravan
- You drive in dusty conditions
- The car is turbocharged (turbo oil runs hotter)
Frequently Asked Questions
Can I go longer than the manufacturer interval?
Not recommended. Manufacturer intervals assume you’re using the correct specification oil. Exceeding them risks varnish build-up, increased wear, and potential warranty claims being rejected.
Should I change oil every year even if I haven’t done the miles?
Yes. Oil degrades over time due to moisture absorption and oxidation, even when the car isn’t being driven. Annual changes are a minimum.
Is it cheaper to change oil myself?
Yes — DIY oil changes cost £20-35 in materials versus £100-200 at a dealer. However, you need to dispose of the old oil responsibly at a local recycling centre.
