You should reconsider. Not only is it a hell of a lot of fun, but you often get more out of it than you do from buying oil.:D

Some will say why do a sample every oil change like I have. When I go to sell this these reports will net me a higher price as they can see for a FACT the condition of the engine.

That won't get you a dime extra from any dealers trade in appraiser, or the majority of private buyers either. Personally I would expect to see detailed service records for things like fluid changes and other maintenance if I was buying used, but why would I pay more because the vehicle was maintained per the manufacturers recommendations?

That oil analysis is fine if you like spending $28 bucks. There are many things that can go mechanically wrong with an engine in a major and expensive way, and an oil analysis report is not going to give any sort of warning for the majority of them

Really? So, when the trucking industry,and many others that operate everything from giant power plants in ships, to back-up generators for critical uses, rely on oil analysis to determine the machine's "health" they are wasting money? Interesting. My son is responsible for countless diesel engines. Like most responsible managers in this specialty, he has a commercial account with an analysis firm, and a steady flow of samples heading to the lab and reports showing up in his inbox. Catching an issue like coolant intrusion, fuel contamination, and impending bearing failure, is a pretty big deal, and pretty evident when regularly monitored with sampling. When shop time is $100+ an hour, and few problems are resolved with less than a four figure repair bill, a few dollars on oil testing is well spent.
