Thank you john,I look forward to the results of your test,exact mpg and related cost/savings will help to answer my ? Is it worth the effort!JOHNWALES said:It is not really a case of being able to afford the fuel, if at the end of the cycle you use less !Having commented on this issue, I intend to give the tank a fill up on my next refill. Apart from BP Ultimate which led the way with premium diesel, I have recently seen super grades with Shell, Esso and Texaco.
A point to also bear in mind, diesel in my home Mid Wales town is currently 140.9 p per litre, but I regularly travel out of the area and use an accurate on line fuel price guide to locate cheaper fuel on my route. On a journey to Cardiff last week end I located an Esso station just off the A 470 near Merthyr which was selling diesel at 134.9 p per litre, which is a huge saving.I did notice that premium diesel on this site was 144.9p, a full 10 p per litre dearer than the standard fuel. In my opinion using the BP Esso and Shell brands is in itself preferential to many of the cheaper supermarket products which often lack essential additives; and I am not sure that filing up with Premium where there is a cash difference of 45 p per gallon is cost effective.
I will report back on my findings before Christmas regards the savings on my B Max.
