Made a start on the service today, swapped the plugs, air filter and pollen filter (did a 19km run this morning, so didn't want to spend 30 minutes under the car doing the oil).
Also, checked the tyre pressures.
Should be 32psi in the front, and 26psi in the rear.
Rears had 20psi, near side front had 20psi, and the off side front had 10psi! No wonder it felt like it was pulling to one side!
Oil change will be done tomorrow, as it's my last day off before going back to work.
