Is this oil suitable for a 1966 Leyland 2.5 diesel?
I was sold 5 litres of it by your Ipswich store on Saturday but upon closer reading, the tin makes no mention of diesels.
I posted a similar question. Whilst there is no mention of diesels, the specification for the oil says its compliant to SE/CC. These are old specs and the SE part relates to engines manufactured before 1979. The CC part of the specification relates to "Commercial" which I have found, through this research implies diesel. Therefore I am using it on my B series BMC diesel.
Hope this helps.
