Hey Burla, thanks for the discussion! But Wow, I'm a little overwhelmed! lol
A little history on my trucks oil.. I ran the factory oil from 0 miles to 4200 miles, then my first oil change I used regular 5-20 pennzoil dino oil, and changed it at 7400 miles. so 2800 miles on the first oil change interval using regular pennzoil dino oil.
i then changed the oil to redline synthetic back in January 1st, and at that time the truck had 7400 miles. So, in 4.5 months time, I drove 10,000 miles on Redline oil, and those are the test results you are reading now. Thats highway driving, city driving, and of course full blast manual shift (or button shift, LOL) driving, hot rodding and full throttle passing is pretty often though, LOL.
The truck currently has 18,250 miles on it, with a new royal purple filter and redline oil @ 18,000 miles.
Yes I have a catch can I installed at 1,900 miles, and I have been emptying it about every 2-2500 miles with about the same amount of oil when i drain it. and I do keep it separate, here is from when I drain it each time, it goes into a new bottle.
