....However, for the last couple of months, my son's Crafter race van has had intermittent misfire when cold and under load. Occasionally it would appear when hot and has gone into limp home on one occasion. A new fuel filter gave a temporary cure indicating the issue may be insufficient fuel supply.
We ordered a new tank lift pump which failed to arrive before the weekend, so he set off on a 500 mile round trip to Wales....and decided to fill with V-Power.
The van ran without fault.
There was certainly a difference, but wether it was do with fuel quality, cleaning agents or just luck, is impossible to say.
The few quid extra for fuel on this occasion was much cheaper than a new lift pump......
