I have a new 2014 Cadillac CTS-V Coupe with a manual transmission and the engine is going through a quart of oil every 1,000 miles. The factory oil is a synthetic blend AC Delco brand and at 1,754 miles I switched to Mobil 1 5W30 with an Amsoil EA oil filter. This engine has been consuming oil since day one on the factory oil. I just went 500 miles since I changed the oil and it was down a half quart of oil. I topped it off with Mobil 1 and frequently check the oil level. I am at about 2,300 miles now.
What synthetic oil if any would eliminate the consumption? I was thinking of going with the Amsoil signature series 0W30, but didn't know if that would cure the oil consumption issue. The oil may be slipping past the piston rings until the rings seat which on the LSA 6.2L V8 may be at about 5,000 miles.
Any advice?
Thanks in advance!
