Volvo says that you don't have to touch the spark plugs for the first 60K miles. This seems too long to me. My '04 is at 40K miles now and I'm thinking that really the spark plugs are over due. What is everyone's opinion here? Also, would you go with Volvo plugs or something else ('04 V70 2.5T).<p>Also, they (as usual) claim that the tranny fluid doesn't need changing at all, but there is a stipulation for changing it if you often tow something or use the car in harsh conditions. Even then, they claim that it should be done at the 52,500 mile service (7th service at their 7500 interval). This also seems too long to me. What is everyone's opinion here?<p>On the '04 service was free up until 30,000 miles. I did the 37,500 on my own and plan to keep doing so, with the help of my indy mechanic for things either beyond me or when I don't have the time to do them.<p>Your input is appreciated. Just about to order some things from fcpgroton, so it would be good to get everything I need at once.
