The oil drain nut is 13mm and really easy to get to. The exhaust is about 6" away so I waited for it to cool down. The filter is awkward to get to. I ended up using a 24mm socket with a universal joint and 1 ft. extension. I recommend laying a towel down by the filter to avoid dripping oil all over the engine. I used 6 quarts of Pennsoil Platinum and a Wix filter. It took about 20 minutes start to finish. I also filled the windshield washer fluid with a very long funnel. That took 1.2 gallons and it wasn't empty. I wonder why they didn't add an extension to that thing so we could fill it up without a funnel.
