As I mentioned in a post above, an oil analysis will only show the condition of the oil change since the last change. If the owner previously went 25,000 miles without an oil change, and has less than 5000 miles on the current oil change, I don't see how a current oil analysis would tell them much about past oil change intervals.My gut feeling is his engine trouble will be a problem Hyundai has seen in the past and an oil analysis would prove he changed his oil regularly.
The terms and conditions of the warranty specify that service must be performed according to the owner's manual (such as oil change interval) and it doesn't say anything about an oil analysis. A warranty is a legal contract between manufacturer and consumer, and the terms and conditions are not open to alternate methods regarding compliance with those terms.
For example, suppose one used the best Amsoil motor oil (Signature Series), which is guaranteed by Amsoil to protect your engine for at least 15,000 miles under severe service. I don't doubt their claim (on their premium Signature product only) but the terms and conditions of the Hyundai warranty specify a maximum of 7500 miles and you must use the appropriate API certified oil (Amsoil only says Signature Series is API "qualified"). So the condition of the oil is irrelevant for warranty compliance, it only matters what kind of oil you use (and filter) and how often you change it, even "if" the Amsoil Signature oil in the crankcase at 15,000 miles was in better condition than any conventional oil after 5,000 miles.
