Case Study: A Mess of an Oil Change!

by Colette Cooley, Cars for Keeps Office Manager

The other day, a customer brought in a 1997 Lexus ES 300 (that he had just purchased) for an oil change and general checkup. The car was in very good condition - that was, until the mechanic took off the oil valve cover and it full of sludge. Having sludge rather than oil lubricating the engine's working parts can very quickly deteriorate moving parts. Instead of being lubricated by clean oil, sludge contaminates parts, makes them sticky and prone to costly damage.

Mike really gets into auto repair...*groan*

The previous owner followed the manufacturer’s guidelines to change the oil every five or six thousand miles - so then what was the problem? This may look good on paper, but in reality, this frequently is often just not enough. The detergents in the oil break down after a certain amount of time, which is what creates sludge. Unless a special high-grade synthetic oil were being used, regular oil changes and maintenance really should be preformed every three thousand miles for this type of vehicle. This Lexus has 167,000 miles on it, and if properly maintained intervals are kept, it should be good for another 500,000 miles and more.

We like to view our customers' cars as investments; in the long run, they prove a far more valuable investment when they're properly maintained. Each car model is different, so if you'd like to know what your vehicle's specific maintenance intervals should be, it's best to check with your favorite mechanic.

Speaking of favorite mechanics, we've been nominated for the category of "Best Oil Change" by the Grand Haven Tribune's People's Choice Awards 2011, and we would appreciate your votes! Thank you!
