Hello everybody, I would like to know if Fram Extra Guard filter could maximize the quality of synthetic oil? Because I could see from the Fram website that the Extra Guard is designed for conventional oil.
Another question is that what is the difference between the Extra Guard and Ultra? Does Ultra justify the 5-dollar difference? How about Mobil 1 filter compared to the Fram Ultra?
Thank you so much!
