Just kinda curious as to what others are putting in their ponies......so far i've been using Mobil 1 fully synthetic 5w-30. Just had my second oil change today.... .....Royal Purple is pretty hard to find around here, so I haven't had a chance to try it yet, but some people say it doesn't make any difference and others say it does so I'm not sure what to think.....anyway, just that i'd start a new thread since there hasn't been very many recent ones.......
