Quaker State 5W 30 Full Synthetic with DEXOS
Would RecommendHave been using another quality brand, but changed over to Quaker Full Synthetic a couple of months ago. as my Cadillac uses 8 qts. The engine has had tiny lifter noises which come with the newest Gen Northstar Engine. I put on 5,000 miles a month and change oil. Now at 6,800 miles the noises are gone. I have 7 vehicles and will use QS in everything. DEXOS has been added which smooths the cylinder walls for more power and the rotating parts for less noise.

QS, because there is no other substitute.
Would Recommend[This review was collected as part of a promotion.] Don't use anything but the best for my Mopars and recommend it to all of my friends. If you want quality, Quaker State is the only way to go, I've spent too little on some oils, and too much as well, but QS has never sold me a bad batch unlike the rest! Thanks Quaker State! Happy Holidays from Anthony Ernst Jr.!!!
