Hello,
My sister have a 1995 ford explorer with 170,000 miles. The car is supposed to use 5w-30 oil... But she ran 25w-50 for 3 years (i don't know why)... So the car had pennzoil 25w-50 for 3 years, She needs an oil change and im doing that job. But i have a question...Is there any risk of burning oil for going from 25w-50 to 5w-30?
