Did my first oil change on my 4 banger a few days ago. What a pain the ass. Well maybe not that bad, but I wish it were much easier. The oil pan drain plug is obviously easy, not hard to access. The oil filter isn't hard to access either. But since I don't the exact oil filter wrench to get the cap off I had to go buy a strap wrench and prey that I don't crack the cap. I was very careful, man they put that thing on there tight. I got it off and changed the filter. The small O-ring on the drain plug was a pain to get off since it fit so tight but the new one went on there fine. I then put the cap back on and tightened it but made sure it wasn't too tight. Can't torque it down to specs with a strap wrench lol. So far no leaks and I've gone 100 miles. I'm ordering the right wrench for next time though.
