Have any of you that are running Mobil 1 and changing your oil at X miles thought of sending any samples out for analysis? If your going to the trouble of using expensive synthetic you might as well drive it up to 5k (or wherever you feel comfortable) take a 3 oz sample and send it out. $20 later you know if your changing it too early, right on or too late. I don't know about you guys but between a nissan filter and the 5 quarts of oil I'm out around $15 on Dino. Mobil pushes that up another $5. Could save you a lot of money and time in the long run if your oil isn't becoming contaminated until 7.5k, 10k , etc miles.
