Two cars on one drive, two different service clocks
Central Road is the only real through route in the centre, and with shop parking, bus stops and crossings along its half mile it slows to a crawl on Saturdays. The North Cheam crossroads where Cheam Common Road meets the A24 is a busy signalised junction with supermarket traffic on top. One car in the household does that sort of trip and little else, which means short distances and a lot of cold running.
The other one does proper mileage, out past Worcester Park station towards the A3 or down the A24, and reaches 6,000 miles two or three times a year. Same interim, entirely different reason for having it. The high-mileage car is working to the odometer, because quantity of oil used is what matters there. The local car is working to the six-month date, because its oil never gets hot enough to clear what short journeys put into it.
We treat them accordingly. Oil and filter renewed with Castrol to each engine's approval, then the car on the lift for tread depths and pressures, pad and disc condition, steering and suspension joints, exhaust and underbody, battery and charging output. The seldom-used car usually needs its discs looked at closely for edge corrosion, and the busy one usually needs its pads measuring. Both get a written report. The ANPR bus gate on Browning Avenue is worth avoiding on the way out, because driving through it without an exemption risks a penalty charge.
Nothing beyond the interim is done without a call and a price in writing, and any repairs carry our 3-month workmanship guarantee. The drive is six miles, around twenty minutes via Cheam Common Road, the North Cheam crossroads and Malden Road to Cheam Village, then the A232 through Sutton. Collection and delivery can be arranged, which makes doing both cars in one week straightforward.
