I've got a few questions. My 97 Z71 has a little over 40K on the odo. The book has some crazy change intervals (100K) for things like spark plugs, ATF, coolant etc. I grew up thinking more often was better (especially on lubes). What are your thoughts on this. Also, how frequently should one change items like plug wires, O2 sensors, ECT. One final thought, everyone seems supportive of mobil gear lube (synthetic). Do you use the same in the rear as the front? What about mobile 1 synthetic oil. Is it worth the $$$. Are change intervals extended at all? Currently I change oil about every 2000-2500 mixed city and Hwy (more often is better mentality). Also, are the ACDelco filters from Walmart better than or comperable to say Fram, Puraltor, or Wix? What is the best oil filter?
Lots of questions here but the days of dinosaur based goop seem to be waning and I have to learn all over again with the new stuff.
As always, your comments are appreciated
