| The Cadillac Northstar V8 is widely known to [http://www.caddyinfo.com/northstaroil.htm|consume more oil] than most engines—as much as a quart every 1,000 miles. Though you may be adding new oil fairly frequently, it's important that you still change your engine oil and filter every 3,000-5,000 miles, depending on your driving conditions. | | Simply using synthetic oil will not eliminate the need to regularly add oil to the engine, since the Northstar is a high-performance engine that requires a lot of oil to run efficiently. In addition, Cadillac (as well as many automotive experts) strongly discourage the use of any oil additives, even those that claim to decrease oil consumption. |
