Short cold trips off the Broadway and a half-year oil change
Tooting Broadway, where the A24 meets the A217, is congested for most of the day, Upper Tooting Road is 20mph and Wandsworth applies a 20mph limit to its residential streets as well. Cars here spend their lives on narrow terraced roads with parking on both sides, coming out for a trip to the market or across to the Commons and going back again. Very few of those journeys last long enough to get the oil properly hot. Controlled parking around the Broadway runs six days a week, which gives people another reason to keep a hard-won space and leave the car where it is.
Fuel dilution and condensation are the consequence. Until the oil reaches full temperature, water from combustion stays in it and unburnt fuel works past the rings, and both reduce how well it protects. The odometer will not warn you about any of it, which is why the interim is set at six months for cars used this way, whatever the mileage reads.
Alongside the oil and filter change we test the battery and charging output, because a car doing a succession of short runs never puts back what starting it takes out, and a flat battery on a Tooting side street is a bad place to discover that. Tread depths are measured and pressures set, pad and disc condition is recorded, and the steering, suspension and underbody get looked over on the lift.
Hospital shift patterns are easy enough to work around: we are open Monday to Friday 8am to 8pm and Saturday 8am to 5pm. The drive is Mitcham Road east into Mitcham, through the Figges Marsh signals and the one-way system to the Cricket Green, then Cranmer Road and Carshalton Road south, about eighteen minutes. Collection and delivery can be arranged, and repairs carry a 3-month workmanship guarantee.
