I only mention this as my friend that services my 75 enjoyed a few weeks (at his employers expense) at the UK MG R factory, prior to the 75s 2001 launch in Australia.
He tells me that staff overseeing the non-stop engine tests (running 24 hours per day) instructed him to only use Mobil 1 0W-40 engine oil. Emphasis was put on the manufacturer’s name as well as the grade.
And this is the oil grade that he (and his MG R Dealership employer) used consistently since the cars local launch in 2001 – without problems.
He continues to use this oil (his employer ceased servicing our marque after its demise). The KV6 design was advanced for its time, incorporating the latest technology. We have a warmer climate here in Australia, but the Mobil 1 0W-40 oil has a good record here.

Oil has been a pretty divisive subject an MGR expert I worked for when I was in school told me to put a thicker oil if the tick comes back he said I was not wrong to use Mobil 1 0w-40 but that was 20 years ago when these cars were new so although I have been exuslusively using this oil on my 75s so far I may give it a try in the next oil chnage the 2 arguments I've heard so far is that the oil is to thin for it to build up pressure quick enough on the other hand what I heard and believed as well a thinner oil will reach and lubricate the valvetrain faster than a thicker honestly you can't make sense each has their own opinions I'll see how it goes so far it seems quiet
