This tutorial only applies to Minis with a manual gearbox. There is another tutorial that covers changing the oil on Minis with an automatic gearbox
(➔ see the tutorial).
The oil is common to the engine and the gearbox.
Change every 10,000 km or every 6 months.
Change every 10,000 km or every 6 months.
Oil volume required for an oil change ➔ 4.9 liters (approximately).
The workshop manual recommends an oil:
• SAE 10W40 for temperatures from -20 to +35°C
• SAE 20W50 for temperatures from 0 to +50°C
• SAE 10W40 for temperatures from -20 to +35°C
• SAE 20W50 for temperatures from 0 to +50°C
It is recommended to use a modern mineral oil specially formulated for classic vehicles (Castrol Classic XL 20W50, Motul Classic Oil 20W50, Elf HTX Collection 20W50, Mini Spares Classic Oil 20W50, Norauto 20W50).
• These oils do not deteriorate the rubber seals of older vehicles.
• They have a high ZDDP content (anti-wear additive) which improves protection against oxidation of metal parts in contact (e.g. rocker arm and push rod).
• They have enhanced adhesion even during long periods of vehicle immobilization.

We use Norauto 20W50 oil on our Minis. At €23 for 5 liters, it's an excellent value for money.
Before changing the engine oil, drive a few kilometers to warm up the engine. The oil will be more fluid and will drain better.
Used oils, seals and filters are hazardous waste for the environment. They must in no circumstances be thrown neither in the natural environment, nor in the sanitation network, nor in household waste. They must be deposited in a recycling center.

Drain the engine and gearbox oil
Op 01
Remove the grille (➔ see the tutorial ''Removing the grille'' Op 01 to 04).
Op 02
Open the oil filler cap.
Removing the oil filler cap will make it easier for the oil to drain.
Op 03
Place a drain pan under the gearbox.
The oil will flow out laterally. Position the drain pan accordingly.
Op 04
Unscrew the drain plug. Use a 24 mm socket.
Let the oil drain.
Discard the sealing washer.
The oil and drain plug are very hot. Be careful not to burn yourself.
The drain plug is magnetic. It retains metal filings. It will need to be cleaned thoroughly before reassembly.

Change the oil filter
Op 05
Unscrew and remove the oil filter. Use the filter wrench.
Place a drain pan under the filter as oil will drain when unscrewing.
Op 06
Thoroughly clean the oil filter mounting surface.
Op 07
Lightly lubricate the seal of the new oil filter (MSF166) with engine oil.
Op 08
Screw on the new oil filter. Screw it on by hand.
Screw on the filter until the filter gasket contacts the support. Then, tighten the filter 3/4 turn.
Never tighten the new filter with the filter wrench.

Add oil
Op 09
Fit the new sealing washer (AED172) on the drain plug.
Op 10
Screw the drain plug onto the housing. Use the 24 mm socket.
Tighten the bolt to a torque of 34 mN. Use a torque wrench.
Op 11
Pour 4.5 liters of oil into the engine.
Op 12
Replace the oil filler cap (GFE6003MS).
The oil filler cap is equipped with a breather. It must be cleaned or replaced every 20,000 km (12,000 miles).
Op 13
Start the engine for a few seconds. Turn off the engine.
Check the oil level. Use the dipstick.
Add oil if necessary until you get close to the ''max'' mark on the dipstick.
Check for leaks around the oil filter.
After stopping the engine, wait a few minutes for the oil to drain back into the oil pan before checking the oil level. If you do not respect this time, the level reading may be incorrect.
The amount of oil between the ''mini'' and ''max'' marks on the dipstick is 0.6 liters.
Never exceed the maximum oil level (''max'' mark). This could damage the engine.
Op 14
Reinstall the grille (➔ see the tutorial ''Removing the grille'' Op 05 to 06).
Op 15
Drive a few kilometers with the vehicle.
Check that there are no leaks around the oil filter and the drain plug.
