So 'Garage' people and those supposedly in the know tend to recommend using super diesel. Of course they don't have to pay the extra premium when I am filling up! The price differential is quite extreme so I started wondering if it is really worth using Super Diesel or Diesel plus, whatever name the service station chooses to sell it under.
Now much like semi synthetic oil is recommended for older engines, mine is a 17 year old BMW 57 3.0 turbo, as opposed to fully synthetic for 'modern' engines, there are those that say you definitely should NOT use super diesel because the engines weren't designed to run on it all those years ago when they were manufactured!
It kind of makes sense so I was just wondering what others think?
I have chosen to save the extra cost and put it into my burgeoning repair slush fund instead, but am I missing a trick by NOT using Super diesel? Some swear by it, others swear at it and say you only need to use normal diesel but put a cleansing additive in once or twice a year for the injectors.

All depends on what DPFs, Diesel Cats, and the like your motor has on it.
Using the Premium diesel will probably reduce the likelihood of problems with those things, so may be worth the extra money.
On older stuff, with mechanical fuel injection and little or no engine management and eco gizmos, it isn't going to be worth while.
I don't really know enough about your engine to know how far along the tech spectrum it falls.
But one or more of the Rangie bods will be along in a bit to clarify.

I am very doubtful using Premium Diesel will actually harm any diesel engines, it just has a bit more detergent, and some cleaning additives in it. But using it if not needed is a waste of money.
 
We use normal most of the year, but premium “super diesel?” For the winter as it has a lower temperature protection.
I wouldn’t think you have to worry about that.

But what are the actual specs of the fuel? What’s so super about it?

All diesel here has anti waxing chemicals added in winter, even the red diesel used for central heating. Never had a problem even when temperatures went down to minus 17C.
