Use regular diesel for your car, the V Power is much more expensive and you will see no gains on a 1.5 (all modern diesels are turbo).
It's the same old diesel fuel that everyone else sells. The Shell garage just puts their brand name on it and charges you more for the privilege of buying it there.
It's a way for fuel companies to make money from the gullible. It makes no difference to performance of 99.99% of cars.
I have a 1.5 turbo diesel renault clio, and always get regular diesel from Shell garage, I always see the pump for Vpower Diesel, and basically intrigued to know what it is?
Is it better for money than regular diesel?
Should i use it with my car, not the most knowledged of persons with my car!
