I had my spark plugs replaced at 40000+ km. (third or fourth oil change) to preserve the (more expensive) ignition coils and due to some audible instability when idling. Idling improved. |

Thats why I asked - having not believed the oil change reference .... and seeing NGK say 20 to 30K miles. Thanks for the Coolant info - there seems to be a debate about how efficacious the anti-coprrosive is after 4 years ... mine doesnt even show a colour any more ! (2019 M140, with some 15K on the clock)

The colour is only a dye. Of course you can replace the coolant for your peace of mind any time. |
