Which engine oil do you use :-) ?

[Jesus325iTouring]

Engine: M20B25

Oil: Whatever cheap p1ss I can find.

Oh, and regards oil leaks, when you you start to lose 2 litres a WEEK, then you need to think about doing something

Which oils was M20 designed for ?

Duckhams hypergrade 20W-50. Strange green coloured stuff.

Good oil back in the day

Sounds like it was a very thick oil with 20W winter setting

I used to use this in all my cars including E30, The stag still has it in

Pony when these cars were made there was no other oil this and Castrol 20/50 was the best at £5.50 a gallon unless you wanted comma at £2.50 a gallon. it goes to show how good they were that the engines are still running today

The stag still has it in

If it can keep a Stag engine running, with its over long chains, inadequate main bearings and marginal cooling, then it must be good!

So would Castrol 10W-60 work well on m20s ?

Wouldn't put it in yours Soni, it's an expensive oil to burn.
