Personally I find BP Ultimate good but am not convinced it is worth paying the premium.

The car feels better, slightly quieter not a noticable difference in mpg but then I tend to drive it like I just stole it.

I drive my C220 CDi like your Grandad's Grandad 'cos I do 25,000 miles a year in it and I'm self employed so I pay for everything. However, I put a couple of tanks of BP ultimate in recently and immediately noticed a noise reduction and an increase from 43 to 46 mpg (mainly motorway at 75 mph on cruise).
I've just gone back to Sainbury's melted candle wax with added paraffin (actually it is still EN 590 spec and JS don't own oil refineries so I assume its OK) and the smoothness and quietness has remained ! I'll report on mpg soon.
Although the BP stuff was good, it cost about 0.5p to 1p per mile more than JS on lower mpg.
It does make me think though, why can't all diesel be like BP Ulitmate ? Is it more costly to manufacture, or is it BP capitalising on what they think the market will take for a genuinely premium fuel ?

I'd be interested to know how you are getting on with this soon as i got my c220 cdi last week - only filled it up once so far and just put total diesel in.

Premium diesels have an additive to raise the cetane value, hence the smothness and extra go.
Just use an injector cleaner/lubricator with cetane improver. Does the same job cheaper.

I've noticed no improvement in fuel economy with BP Ultimate, so I tend to stick with their normal stuff or whoevers selling the cheapest diesel at the time.

BP Ultimate Diesel takes at least 5 fill-ups to start working. My mpg to work has risen from about 36mpg about 6 weeks ago to a whopping 40.2mpg I got this morning. Also the car seems to be running smoother now. I've put about 6 or 7 tanks of the stuff in so far.
