View Full Version : Oil change

07-10-2011, 04:53 PM
I am looking to save some money and do a oil change on my 89 prostar 454 420hp. What will I need to have to remove all of the oil and what type of oil do you suggest running ( brand and viscosity)? Also where is the oil drain plug/ hose located?

Check out the knowledge center on this forum then download a owners manual for your year and boat and change with whats recommended in manual it will also say where the drain hose is located...

Also, determine if you have a flat tapper or roller cam (I suspect the former). If you have a flat tapper cam, I recommend an oil that still has around 1,200 ppm ZDDP such as Valvoline VR-1.
