Ok guys, this might sound like a dumb question but i would like your guys opinion. Im gonna do an oil change on my car. But im to the point to where im confused on what oil to use for my car. Ive been using synthetic oil (Castrol 5W-30) but there are so many out ther there that claim to be so good. Whats the deal? What oil do you guys use or suggest i use? And also an oil filter. Ive been using WIX oil filters buti dont know if there are any other filters that do a better job at filtering the oil. Thanks a lot for your guys opinions and ideas.
