Hi All, What should I be replacing or checking on my k11's 100,000 mile service, I could give it a basic service but is there anything else I need to do example replace the thermostat as I don't know when that was fitted last and the radiator is looking old as it is probably 24 years old. I had a major service done at 94,000 last October & had the clutch replaced in February this year. And I'm using 15w40 oil which my mechanic told me to change to 5w30 , which is weird as the MSC quote 10w40 oil . yours Peter Rowley
