Proton Jumbuck service: key facts

Oil service every 10,000 miles or 1 year
1 generation from 2003 to 2007
5 tracked service items across routine, major, and periodic schedules

Routine service items

These are the items covered in a standard service. Most garages include oil, oil filter and a basic inspection. The rest are typically checked or replaced on a schedule.

Service item	Interval	Typical cost
Engine oil and filter Standard interval for naturally aspirated petrol engines of this era. Change oil and filter together. Missing this service leads to premature engine wear and potential bearing damage. GEN1	10,000 miles or 1 year	£80–£120
Air filter Replace when dirty or restricted. Clogged filter reduces performance and increases fuel consumption. Check more frequently in dusty conditions. GEN1	20,000 miles or 2 years	£25–£40

Periodic maintenance

Items that don't need doing at every service but should be on your radar at the right mileage or age.

Service item	Interval	Typical cost
Spark plugs Standard plugs for naturally aspirated engine. Worn plugs cause misfiring, poor fuel economy and potential catalytic converter damage. Replace all four at once. GEN1	30,000 miles or 3 years	£60–£100
Brake fluid Two-year interval regardless of mileage due to moisture absorption. Contaminated brake fluid causes brake component corrosion and brake failure. Critical for safety. GEN1	2 years	£50–£80
Coolant flush Replace coolant and thermostat together. Old coolant loses corrosion protection leading to radiator and water pump failure. Flush system completely. GEN1	60,000 miles or 5 years	£120–£180
