I need to change the oil this weekend. It holds 4.5 quarts. I have 4 quarts of Pennzoil Platinum 10W30 left. I have some leftovers laying around......half quart of Pennzoil Platinum 5W20, about a quart of Pennzoil High Mileage (conventional) 10W40,and a half quart of PYB 10W40. Which oil would you use for that "half quart"?
These cars are not supposed to use anything "thinner" than 10W30 per Nissan fsm. Would a half quart of 5W20 be the least bit harmful?
