It's been a while since my last post....mostly been reading. Anyway, I just finished reading the 101 guide, and learned a lot from that. About 1.5 years ago, I purchased a Honda Civic 1.5L 5 speed with 150k miles on it from a buddy of mine who bought it new. I don't think he was much on preventative maintenance, and as soon as I bought it I started running Castrol Edge 5w30 in it (from reading up on the forum about that oil at the time, it sounded as good as you can get over the counter). I now have 188k on it, and after reading the 101 guide, I'm thinking of trying out the new 0w20 oils, and I found it on sale today at O'Reilly's for $4.99/qt. What do you guy's think? I've been doing OC's at 7.5k and using either Napa Gold or Purolator Gold. Thanks for any input......
