1. diesel exhaust fluid (def) is used to reduce nox emissions.

Explanation:

1. Police cars have high - stress usage, long road trips, short trips, and extreme cold conditions are all severe - service scenarios.
2. Synthetic and conventional oil should not be mixed. Warranties may not be voided with aftermarket parts in some cases. Oiling wheel studs when reinstalling lug nuts is not recommended. Tire pressure increases after driving. Honda/Acura transmissions are usually checked with the engine off.
3. For chassis lubrication, "GC" grease can be used, and if it has "LB" too, it's still suitable. Manual transmissions use gear oil, not engine oil or ATF or DOT 5. The door - jamb tire sticker has accurate tire inflation info. Diesel exhaust fluid reduces NOx emissions.
