Anyone have statistics on the typical life of a 2.5 L engine?

Trust me.. Its not a bad thing.
Ever thought about all the contaminants the oil is susceptible to? Coolant intrusion, fuel intrusion, condensation are just a few that need to be purged from the engine at an oil service. Seeing what we gather from UOA and what I noted while using an Intellistick device in one of our test cars, even 5K is pushing it for the oil in these engines.

Well trust me Jake, I may have surfed the fortune 100 wave but their ways are not mine. I thought if you were using a major oil manufacturer to formulate this they would certainly have a stake in production, I was wrong.

I don't care anything about a Fortune 100 Company.. As long as I can work on the property where I grew up, take an afternoon off to go fishing at our on site Pond or go Hunting out in the woods below the shop I am perfectly happy..
These oils are low production runs, made in batches of less than 500 gallons, or in some instances only 5 gallons. Due to this the volume isn't that critical and dealing with a company like Gibbs who has 400+ employees all dedicated to supporting just 3 NASCAR teams, they understand development, its cost and how the game is played.
I will post data logs of street oil temps and race oil temps later along with some pictures of some secret sauce in 5 gallon pails down in my lab. I am trying to finish an engine on the dyno currently.. Took a break to grab some chow and relax for a few minutes.. Day started 14 hours ago and I haven't stopped yet :-)
