Today I had my oil,and oil filter changed at walmart. My truck is a 1995 nissan 4cyl. man. transmission pickup truck,with 240k miles. I use Mobil 1 High Mileage 10w30 oil. I had a Fram Ultra synthetic oil filter put on. This is the first time I have ever used this specific oil filter on my truck. Is this oil filter good for 15k miles on my truck? My thoughts were to replace the oil after 5k miles,but not replace the oil filter until at least 10k miles. Is this safe for me to do?
