Percy Hoff, President ofDSG Power Systems, owner of the4+ Fuel Additivesbrand says that in modern diesel fuel systems, the ultra-low diesel fuel and heat generated by new high-pressure fuel systems cause deposits to form inside injectors. When machinery is stored, these deposits can harden and result in non-start issues or worse… damage to the fuel injection system. A good fuel additive such as4+ Premiumwill clean up and refresh your fuel after winter storage and keep your fuel system in top shape during the summer months.
