should be an informative thread to get a peek at what people do to their CTS. I have a 2017 CTS 6.2L and the engine needs 10 quarts!!! I decided to change it with all of these products and do it myself as the dealer wanted a large amount of money to flush the transmission, oil, and change the filter and coolant, here is what I ordered

Also ordered this engine cover, a bit pricey but I dunno, call me weird, but I like it
2017 Cadillac CTS Engine Cover - 3.6L V6 (LGX) 12662929
my wife thinks I am nuts!!!

ok your turn!
