VIPER, oh great messiah of A/C mods and electrical bits...
I am a bit confused good sir (easy to do).
I thought you had a used 2005 Elise for a while now? What would a report of this nature tell you about your vehicle that you don't already know? Would it tell you that your engine is falling apart or that it is wearing out too quickly?
Did you acquire a second Lotus? I saw that you posted about rusted rotors as well... which is why I am so confused.

I had high silicone in my 1st post-break-in oil change analysys (1st change after 1,200 mi - @3k). I'm bringing my latest 10k change in now for comparative analysis too, and will post my results for exhulted comment as well. I had 3 change intervals between, BTW, as I am changing RELIGIOUSLY at between 2.5k, no more than 2.8k mile intervals. All "break-in" influenced ressults/readings should be well flushed. So, we'll see!

That's funny :bow:
Here is my reason, and since you asked I will tell
.
My belief is that although car manufacturers give both a mileage and time limit to change the oil, the time does not really matter, and is irrelevant, because oil does not degrade by just sitting there and not being run in an engine. As long as it is changed within the mileage limit then that if fine, irrespective of the time. There is in fact, only one reason oil can degrade in a condition of not being run in an engine, and that is moisture absorption from condensation. You might note that my oil has 0.0% water content. Well here is the kicker, my mileage was 5723 miles between changes, less than the 7500 miles limit, but the time was 1 year 11 months, not the 6 months stated. I did this test to prove to myself this theory. I might add that in certain parts of the country, condensation may be a bigger problem and extended time would not work.

It may be funny, but it is true good sir! :bow:
I understand now. Thank you!
May I then ask this question: since the oil does not degrade as claimed, is it best to change it more often if one drives their vehicle more often? What would have been the difference of a daily driven car? Say @3500 Miles as opposed to @7500 Miles

I think that following the Lotus recommended mileage change schedule for "normal" & "special" conditions is the right way to go. "Special" conditions, 4000 miles, refers to "dusty roads", "mountainous areas", shorts trips where the engine does not get hot, track usage. A lot of people are into this more frequent oil changes, but my belief is that it is a waste of time. If someone, and I know that this is most owners, want more frequency, that is fine, it's just that I won't.
