What kind of coolant should I use?
GM tests all their engines using long life DEX-COOL coolant. Therefore, Crusader recommends DEX-COOL or any good extended life coolant (pink/orange in color) mixed 50% DEX-COOL to 50% water for engines that have a closed cooling system. More than 50% coolant can contribute to overheating. Do not mix or substitute DEX-COOL with traditional silicated coolant (green in color).
What type of oil should I use?
The recommended oil for most of our engines is 15W-40 conventional oil. If the engine is an XR7 or XS7 the recommended oil is 5W-30 synthetic oil.
Can I use synthetic oil in my PCM engine?
Synthetic oils are not recommended for use in Crusader engines. Synthetic oils may offer advantages in cold temperature pumpability and high temperature oxidation-resistance. However, synthetic oils have not proven to provide operational or economic benefits over conventional petroleum based oils in Crusader engines. Their use does not permit the extension of oil change intervals.
When should I change my oil?
When an engine is brand new, the oil should be changed after 25 hours of operation. Engine oil should be changed every 50 hours or once per year, whichever comes first.
