Today we have a lovely M3 in for a inspection II Service. Here’s a few shots as the work is carried out.
BMW list the manual gearbox oil as lifetime, you can see its condition pictured below as we are changing the oil. This car has covered just 52k miles and the oil looks worn.
We are refilling using Millers competition synthetic gear oil, ideal for M cars.
Refilling using a oil pump.
You can see the new fuel filter fitted also.
