I suspect a standard multipurpose oil in a premium container with a premium price. Do you think this could be true of all manufacturers?

As said in post #1, there are differences in specs. between many Castrol oils so I don't think it would be wise to :shrug: and consider them all the same.

Castrol 0W-30 has something of a cult following (especially in the USA) and Mobil 1 oil is highly respected by many so I'd say these are class leaders.

What I find intriguing is Mobil 0W-30 has a different (ACEA) spec to Castrol 0W-30 which is surprising as you'd expect them to be interchangeable.

Anyway, I'll be a Mobil man as of Monday so it wont concern me after that

Silkolene who are one of the top motorbike oil manufacturers sell a road bike oil and an off road bike oil. the packaging is the same bar different stickers. Price difference is about 75p-£1 a litre and to quote a silkolene salesman "its exactly the same stuff". Whats all that about then?

Funny that the Castrol bloke didn't say why they discontinued the diesel oil.

Used Mobil1 0w-40 Turbo Diesel for the last 50000 miles and not had a problem.

It's about £28 for 5 litres from Costco if you know anyone with a Costco card.

Argo,
Just found this thread ! (note to self look more often)
I use a 5w-40 ,as for the make it is made by Fuchs as i am told by the supplier, it is re-packed into 1 gallon cans by a company called penine lubricants. It makes no mention on the can whether it is for diesel/petrol engines but it is good stuff
I used that in my Brava JTD for years too and never ever gave me any prolems at all and the price 15 of your best shiny pounds !!

Kind regards,
