Hi Everyone, I'm wondering what the recommended oil is for my 2001 Honda Civic HX. It has 215K miles, and Honda recommended 5W/30. I live in NY. Sometimes I drive easy and other times more spirited. Probably 70% easy, 30% spirited I live in a rural/suburban setting and often spend time on backroads, highway, and state roads. Very little city, but some. My car has no issues besides a very minor oil leak at the oil pan. I don't know if synthetic is better than conventional, and I don't mind online/in store. Price is a factor, as I'm a student. I will go however long between changes is recommended, but typically aim for no more than 5k miles. I've been using castrol GTX, and was considering castrol gtx high milage. Filter recommendations are welcome as well. Thank you very much!
