My husband and I are divorced. I got the 2012 Cadillac SRX and need to have the oil changed, he says that I should use Mobil 1, full synthetic 15w40 Diesel...is this correct??
Is this something I would buy and take for them to put in, or will most places have it when I take my car in for oil change? He is in the oil business, just wanted a second opinion.
