Just had my 33k oil change yesterday at the dealer. No leaks. After making my minor bolt mods I am still amazed at how this engine performs. 13.8 second 1/4mile times and not even running headers or a tune.
I bought mine with the extended warranty and oil change package. If something goes wrong there is a complete history of service. If the car starts to have issues as I approach my 75k mile end of B to B warranty, I guess I will go with a Mustang next depending on how the next Gen mustang looks. Keep in mind that Caddy will be using these engines in next years setup with twin turbos pumping 420hp and 400 something lbs of torque in the CTS. If these engines cause them problems in there flagship car it will be bad....real bad.
