[QUOTE="penright, post: 24813, member: 5208"] I'm thinking about doing ours at 3K. The dealer will do the first one for free, but they said to bring it in at 7K. I don't want to wait that long, because of what [USER=8099]@sdhow[/USER] said. I am guessing they will still do one free at 7K and do all the other things. Did I read right the oil is 0w-20w? That does not feel right. The Honda was 5w-20w, but I did 10w-30w. I think it is a way for the car manufacturers to post better mpg. I have had a couple of 3.8 Grand Prix. When I replaced the bypass, I would flush and replace it with green, thinking DexCool bad. Both of them I replace water pumps and lower intake gaskets. I got rid of them around 250,000 miles.
