Engine oil

There’s a whole generation of drivers out there now that have never really had to check engine oil levels. Modern cars, many don’t even have dipsticks, tend to do it for you.

Wiped dipstick showing Max and Min oil level marks.

On a Morris Minor, according to the manufacturer, it should be done weekly. So, how do you check it on an a-series engined Minor? It couldn’t be easier…

Castrol 20W/50 motor oil.

My favoured brand of motor oil is Castrol Classic. But any good quality 20W/50 motor oil, such as Duckhams, Millers, Mobil etc will do. Whatever you do just make sure you don’t use modern synthetic oil.

  1. Pull the bonnet release, which is in the parcel shelf area located down and to the right of the steering wheel.
  2. Press the bonnet release catch down, which is to the right of the bonnet badge.
  3. Raise the bonnet.
  4. Ensure engine is cold. Oil expands when warm so you’ll get incorrect readings if the engine is warm.
  5. Remove the dipstick. Wipe the dipstick with a rag or a piece of kitchen roll, then replace it in the engine.
  6. Remove the dipstick again and check the oil level. It should be on or between the Min and Max levels. The oil should also look clean. If it’s black it needs changed.
  7. If a top up is required remove the oil filler cap on the rocker cover (top of the engine) and top up a little at a time, thereafter repeating steps 5-6 until oil level is correct.
  8. Reinsert dipstick, close bonnet and happy motoring.
