Can you recall seeing a DT40 analysis that might show how long the oil is good for under a certain set of circumstances (summer in NC, daily driver, xxxx miles put on over 4 months, etc., etc.)?

my research seems to indicate that this is pretty good (as some people go through and it is acceptable to go through up to 1L per 1000 miles)?

Seems like the biggest concern if one of burning or using a lot of oil is bore scoring?

at 4,000 I will change and blackstone it. Since I still have "enough" oil, should I "top it off" or just leave it til next oil change?

You're better off where you are than overfull (all the way up the gauge) but to the top line is the ideal level. Since you have about 1,000 miles to go until your next oil change, you may drop down 1 more major line between now and then, which is a not terrible, but a little too low. That's why I say top up a little now to get back to the top line (not full gauge) and that will probably see you through for the next 1,000 miles until the change.

He all of the sudden got real serious and said that I may want to be careful before doing any aftermarket parts to the engine, because if something did happen to it, a non-OEM part would just give the warranty company a reason to deny the claim. Then later I was thinking that even using the LN engineering oil filter thread-on adapter and a different type of oil filter could potentially be a reason to deny, and maybe even magnetic oil pan nut?

I guess now I need to rethink having the IMS solution installed until maybe just before the warranty is expired, and even wonder if even using some good preventative measures may be an “issue”. Come to think of it, the Joe Gibbs Racing oil DT40 is not a Porsche Approved product, so that may not be happening for a while now either.

Anyone familiar with this type of situation? It would really stink to have an extended warranty and while trying to prevent future problems, void my warranty and then have it bite me in the butt later.
