We average around an extra 10 mpg using Shell V Power diesel which offsets the extra cost & our older engine definitely ran smoother & quieter but the difference is not so noticeable on our newer ones.I forgot to say, when I brimmed it in Woodbridge it was with Shell super duper V power diesel.. don't normally buy it, but went into a pump with no other choice.. .. .. so gave it a treat ..
so perhaps the V power diesel does improve MPG ..
