Do I need to add additive into the new Environmental Diesel (Euro V)?
Caltex Environmental Diesel (Euro V) contains a proprietary, advanced technology, multifunctional additive system that maintains fuel injector cleanliness and protects fuel system components to ensure that engines operate at peak efficiency and performance. It also consists of a lubricity agent to minimize wear on fuel injections and fuel pump components. So, there is no need to add extra additive to Caltex Environmental Diesel.
