Getting toward the 24,000 mile mark on a V6 auto 4X4 Frontier. Oil changes have been at 4,000 intervals. Dealer is recommending adding two "additives" to fluids at this service. Is this normal? What else is common to do at this service?

for the 2007 Maintenance Guide to get an idea of what is required. These statements are from my 2006 Frontier Owners Guide:
"ENGINE COOLING SYSTEM
"The engine cooling system is filled at the factory with Genuine NISSAN Long Life Antifreeze/Coolant to provide year-round antifreeze and coolant protection.The anti-freeze solution contains rust and corrosion inhibitors. Additional engine cooling system additives are not necessary.
"Aftermarket fuel additives
"NISSAN does not recommend the use of any aftermarket fuel additives (for example, fuel injector cleaner, octane booster, intake valve deposit removers, etc.) which are sold commercially. Many of these additives intended for gum, varnish or deposit removal may contain active solvents or similar ingredients that can be harmful to the fuel system and engine.
"Oil additives
"NISSAN does not recommend the use of oil additives. The use of an oil additive is not necessary when the proper oil type is used and maintenance intervals are followed."
