I'm going to Newcastle (Blyth Tall Ships) tomorrow about 300 mile round trip, I'll see what it does.
Gents.....for what it's worth, I always use it because I was reliably informed that, yes......most fuels come from the same refineries in the same tankers, but that certain supermarkets then add things such as ethanol (I don't think diesel contains ethanol but you get my drift) at the pumps. I ran a petrol 2001 6cyl bmw touring for 15 years and came to the conclusion that the premium fuels were worth the extra. It ran better and definitely returned better mpg. My sister in law ran a diesel vw.......lots of stop start town driving......ran like a pig. I advised her to try a premium derv and hey presto! I'll be using premium derv when I pick up my new T6 this week.....and I'll be adding diesel Rhino too! Maybe over kill but I'll have it a long time so it'll be getting additional intermediate oil changes too. Cheaper than a new engine!!
Just my tuppence worth.....fwiw!

mmmm, I need to work on the eco driving; 85mph on Adaptive CC, 300 mile round trip at ave speed for journey 70mph = 32mpg with Millers adaptive. But what a superb drive Love it, Love it, Love itI'm also quite excited that I managed 41mpg on a run down the A1 at a steady 70 yesterday, best figures so far!
I didn't use cruise as it stops the coasting function and costs me 2-3 mpg on average.
Oops yes I get c35mpg at 80+ too......mmmm, I need to work on the eco driving; 85mph on Adaptive CC, 300 mile round trip at ave speed for journey 70mph = 32mpg with Millers adaptive. But what a superb drive Love it, Love it, Love it
