What oil does the dealer use? I don't think he knows...

I will most likely start changing it myself once I'm out of free oil changes.  I think I still get one more more for free, but after that I'll switch to Delvac 1 or Rotella T6.


I used to get the free ones when I bought a vehicle but I have seen the "lube techs" most dealerships let practice on our cars, and there is no way I am letting some 16 year old kid change the oil on my $60k truck.  I just don't trust them, and with the preferred customer discount with amsoil a 2.5 gallon jug is only $63.75 and their synthetic fiber filter is $15.25. It doesn't cost that much and I have access to a lift, so I get all the reassurances that I greased all the fittings and checked for worn parts.  I feel it is more peace of mind for me while towing my 17k fifth wheel down the road knowing exactly what is under my truck and what condition it is in.
