I am new here to BITOG. We have two vehicles in my family. One is a 2004 Hyundai Elantra (96k miles) and the second is a 2005 Dodge Caravan (88k miles). I have always changed oil every 3 mos/3k miles with whatever cheap conventional Wal Mart had. Usually Super Tech 5w30 and a Super Tech filter on my other vehicles. I got both of these cars in the past 6 months. I don't have easy access to a garage at our apartment complex and have to drive 20 miles to a relative's house to change oil. I am thinking of using OEM filters and an inexpensive synthetic like Quaker State Ultimate Durability. Would this be a good combo for 5k on these cars? They are driven about 50/50 city highway.
