Wooooooo, so I should perhaps call myself lucky because at that time, I was not living in USA. At the same time, we should remember that $100 back in 2009 had much more value that it has now in the year 2015. So, it must be probably just like filling your tank in $300 nowadays.
The latest used oil analysis is ready, and the results are excellent. Total mileage on the oil is 5,799 miles. What I am happy to see though is that the ConocoPhillips and Ford Study, which showed that changing your oil more often actually increased engine wear seems to be true, and repeatable. One would expect the wear not to only double, but maybe increase exponentially as the oil "breaks down" and provides less protection. What we are seeing is the opposite, the more mileage on the oil, the wear is slowing down, and in some instances decreasing! In other words, I have been telling people that the more often they change their oil, the more wear they are causing their engines. This seems to prove it's true.
