OIL Analysis.....
Have any of you done this with Royal Purple or Amsoil? It seem the max change interval for Red Line is 7500 miles.
Comments or Observations please...

Here's a similar run of testing for Mobile 1:

(thanks for Dr. Z for the link)
Bottom line, they ran Mobile 1 for 18,000 miles (not a misprint).

so everything but the viscosity are within spec. how does regular motor oil compare to those values? I use High Mileage Castrol, thinking about getting it tested for the heck of it.

Good link.
But I think them adding 6.5 quarts during the testing helped. I don't think there numbers could be to accurate either considering that the test procedure states " collect engine oil from the middle of the drainage." I would like to see someone do strait 7500 miles on mobile 1, then test, with no additions of oil.

Well if you consider the 6 1/2 quarts added - they changed the oil twice(approx) in 18000 miles...thats 9K intervals with no adding - anyway the test was damn ballsy-espically for the guy who owns the Chevy- with unexpected results....doubled my change intervals to 5K!

That's brutal. Thier 'yotas should be taken away from them by 'yota services for " 'yota abuse."
'yota services -> child services..

Here's a 10K run with Mobil 1 5W-30. I think your wear numbers look "ok." Note how low your iron is compared to mine. The oil is probably gone though IMO which may be why it got a little thin. When the TBN gets below 2 it's time to change. Redline isn't known for being an extended drain oil.
I have one more run with "doctored" M1 off for analysis. I have German Castrol Syntec 0W-30 in my truck now...

I stopped by the Stealer to check on my Knocking prob (I think I stumped the masses) and I was telling the rep about my 5K Mobil 1 intervals...he did mention something interesting-IF any gas was to bypass the rings it dosent 'mix' with the synthetic as it would with dino..therefore it can play havoc with your bearings....
gonna get a analisis on mine and see what condition the internals are in. :chicken:

damn... the industry really IS brutal.. that's why I always advise doing an oil analysis before purchasing a used vehicle.
And yah, a lease is just like a rental... so true; u can do whatever you want to is; as long as it looks good, everything is okay. Good point!
