I wanted to get a poll on everyone's thoughts on maintenance. What you read in the service manual and what the dealerships tell you are totally different. For instance they recommend coolant changes at 30,000 when the book says 100,000. Or what about automatic transmission service. The dealer told me yes 100,000 is recommended from Toyota but if done at 30,000 whe can find a problem early if you have one. What I was wondering is what most 4 Runner buffs do. I mean I want to make sure my car is serviced when needed but I don't want to do unnecessary service if it's not needed. Any information would be helpfull. Thanks.
