It's nice to have information about what is going on inside the motor.
It's not required to have the information.
It's worth the $35 to some of us. It's not worth it to others.
Plenty of room for people on both sides.
I had a few analyses done on my CRX. I found that an extra-long oil change interval on it resulted in significant amounts of wear metals--not so good. I will have one done on my MINI at the next oil change, if I can talk the dealer into filling up the little sample cup. I'm curious to see what the levels are.
