My son has used Jim's for years and I decided to give them a try when they offered their "Auto Club" special, $79 for four oil changes plus other discounts (actually I got a fifth oil change 'free' for being one of the first 20 to respond to their offer). So far I am pleased with their service. In fact, when I took one of my cars in for an oil change, the oil had less than 1500 miles on it after 4 months and they suggested I could wait another 2 months because the oil look nearly new. They found a very minor oil leak which they said they would watch to see if it becomes a problem.
