Diesel engine oil - Steve Osborn
I service my own cars and motorbike. Recently I had to top up my Ford Escort 1.8 turbo diesel with engine oil after a service. I didn't have any diesel engine oil left having bought 4 litres instead of the required 4.5. Could I use ordinary engine oil providing it is the correct viscosity? There was nothing on the can to say that it can't be used on diesel engines.

Dear Steve,

In an emergency, yes. But long-term, especially with a turbo diesel, it is advisable to used turbo diesel specific oil.
