PM me for a sample kit, they're only $60. Blackstone charges for the equivalent, $200+ and they still don't address your issues.
I've seen enough Mobil 1 UOA on the GT-R to know it just doesn't work for the GT-R, even dailys. Improve the ring seal and increase power/efficiency and decrease wear.
Tribologik(no longer there) is a commercial lab, meaning airplanes, fighter jets and lots of Navy stuff. I used to get grilled big time for spending time with "cars". Their automated system really won't help you much as it's not properly designed for an automotive application. On an F-35 where everything is always the same, it's different.
Shawn and I have reduced wear by 90% in the piston/cylinder head region and 50-60% through out all the bearings, oil pumps and his turbos in his engine. We increased his ring seal and combustion dynamic by over 50% on the track. Once Shawn gets some free time, we'll be able to compare the data logs on his engine and see what comes back.
Redline's issue was it couldn't seal up the gap between the cylinder wall and the piston, better know as ring seal. It did well in the past, because fuel dilution creeps up on you when left uncontrolled. It's exponential over time and not linear. So you'll see an oil do well but as you continue diluting, your wear values will slowly rise, leaving you confused as to what's happening. This is not something that happens overnight, but rather over time. Then usually stuff gets blamed on wear and tear, age, power, driving style, etc when it was really an oil issue to begin with. Your engine suffers more wear at start up than it does on the track. Only way track driving would be harder than start ups is if you pulled your rev limiter out and left a brick on the gas pedal.
On my 383WHP car, the difference with new oils(RLI vs. Amsoil) was 6WHP and 4lbs. I wish I had the money to test tracked oils and do more science experiments with what the difference in power is once they've been used quite a bit. The power difference as the vehicle's power rises is greater and the stronger the ring seal, the more power, especially on FI, I'm N/A.
Shawn's GT-R makes 500WHP, I think? So imagine what the differences are for those of you cranking up the power. The more power you make, the more you need an oil, fuel, air filter, oil filter and additives combo to keep you protected.
E85 is an amazing fuel, easy on engines, very easy on them.
edit: We're going to bring Shawn's wear values even lower. Shawn and I aren't done just yet. Just sit back and watch.
