Re: Oil Change Interval And Oil Filter?
None taken. I am not disagreeing that the engineers are very knowledgeable , but keep in mine the recommend maintenance schedule is determined by only what is needed to achieving the average life of the vehicle. My background is electro-mechanical maintenance and my experience has shown me that lubrication and filtration is the leading cause of mechanical failures. Providing that engine you have in your happened to be built within tolerance on that day it was built as where all the sub components, more frequent oil changes can only extend the life of your car if they are preformed correctly. It is true oil company's want to sell more oil, but remember car company's also want to sell more cars. Their prime objective is to produce a car that will last throughout the warranty period without any issues, after that they want you to buy another car.
If you change your own oil it is really no major expense and takes all of about 20 minutes or less. I guess it all depends whether what you save in oil out weighs the cost of maintenance later.
