I wonder seeing so many minimum oci's taken and uoa's done with so few miles, is the data collected suitable for discussion on wich brand of oil is better than another? with so many varibles in question I would like to think your results are best if you stick with a brand for a certain amount of time. I find near impossible to spend $20 on a sample with less than 10,000 miles on the oil. My first oil sample I ever paid for had 40,000 on the oil. Question is how much time or milage should be used before comparing results? I see many users having multiple brands trending over a normal intervals, I cant see this benificial to anyone except the lab processing the results. UOA inception was for people who wanted to use an extended drain interval program and have a way to monitor the progress. Im sorry a 3000 mile UOA is not very helpful, at all to me.
