In my 2002 Nissan Pathfinder, can I use full synthetic oil, a blend or stick to conventional oil?
You can use any of the 3 as long as the weight is correct. I am a die hard synthetic user, see no value in a blend but this engine will do just fine with conventional oil. Your choice.
Do you have the same 2002 Nissan PathfinderSUV?
Look on the oil cap. It states the oil viscosity that should be used.
It’s your decision of what type of oil to use.
Nope, just a gear-head
