I agree with the above post.

its not a matter of money, or a "cheap oil change", its about what physical properties each has to offer and if there really is some bad qualities to synthetics.

I don't presume to have anywhere near the experience or knowledge that some of you other posters have. However, a number of years ago I led a team of analysts who were developing software for the Navy to use in its submarine force to monitor and plan maintenance. They were especially concerned with predicting failures so that maintenance could be performed while in port rather than experiencing a failure while on patrol. Remember that they stayed submerged for 60 days while on patrol. Among other things, they were concerned with the trend and with threshold alert levels. From the trend, engineers could do a projection and compute a probability of failure within a certain time period and schedule a maintenance action. If contaminants or metal particles reached a specified threshhold level, regardless of the trend, they would also schedule an action. Of course, they collected a lot of information in addition to oil analysis in their database which was used for decision-making.

Interesting... I am sometimes contracted to analyze the contaminants and metal particles in the oil for submarines.

I understand that many of these techniques have now been implemented on the surface fleet also -- at least for mission critical machinery.
