Some haulage company's used to forbid you to fuel up with city/ultra low sulphur diesel, in fact it was a sackable offence. If you fuelled up a Volvo truck with this crap, not only would you get the sack but the warranty on the tractor unit was null and void. I'm talking of a few years back when this crap first became available, Volvo trucks have now evolved and can run on city diesel. It's a bit like driving with flat tyres, so it's something I would avoid doing. Costs more in the long run due to the **** poor performance.
