As stated, I would try the Pennzoil Platinum HM.
My dad worked for a Chrysler dealer as the service manager. He despised everything Chrysler except all of the vehicles with the "360 V8". He ended up purchasing a 97 (maybe 98) Dakota R/T. My parents LOVED this truck. To this day it is their favorite car. My dad romped the snot out of that thing and it kept begging for more. They eventually had to sell it because it wasn't practical with two car seats. I'm glad to see one of these cars left on the road.
