2008 Prius with 112k miles Got new tires, new 12v battery & oil changed =What else do I need for a 3k mile trip?
We splurged on both medium and thin memory foam seat cushions. That way we can change seat comfort and posture occasionally while making our long trips. I would suggest also getting a small lumbar pillow. It makes a big difference over having just the original seats. EDIT: I also carry a couple of extra quarts of oil in the little storage area in the back behind the rear wheel, a gallon of water and a portable jump starter/air compressor. It never hurts to be prepared for something unexpected (like finding out your Prius suddenly started burning oil and you're miles away from help).
Iridium? NGK now makes Ruthenium HX spark plugs. They say they are even better than Iridium plugs. What this means to us??? https://www.rockauto.com/genImages/100/ruthHX.pdf
