I changed my oil yesterday to the Rottella -T 15-40 and ran my car for about 30 min yesterday. My question is do I have to add anything else to this oil. The only difference I noticed was the smell I guess that will go away. What can I expect?http://img.photobucket.com/albums/v145/mr1940/Mar0404.jpg

My opinion...
Add nothing.
Just drive it.
And when I say that, it means that a 'drive' should be at least an hour in length, time wise (your mileage may vary;)).
You want the engine to get hot enough, for a long enough period of time, to evaporate any condensation in the crankcase, and to dry out any condensation in the exhaust system.
That's where the acids get into the oil and exhaust and start messing things up.
So, go out for a cruise, and use the 'It's for maintenance' excuse![}:)]

Just in case,.....I put a pint bottle of STP Engine Treatment in with the Rotella T. It has the zinc compound in it, and can't hurt.

I was speaking with an engine building friend of mine. He's done independent testing & chemcial analysis of several oils & says that while Rotella has more zinc than regular passenger car oils, it falls well short of what it claims. He said the Delo (CI-4, or CI-4+ NOT CJ-4) was within tolerances of what they claim.

He recommends Brad Penn oils (old Kendall green) in racing versions, Joe Gibbs racing oil, & Redline - all with 1100-1400ppm ZDDP.

Kendall, evidently, was bought out by conoco/Phillips 66 and they moved the plant, changed the oil & additives and it's no better than any other conoco/Phillips 66 oil - also brown now instead of green.
