No one should underestimate the importance of regular oil changes as part of his or her vehicle maintenance schedule. Many people who are very busy or who are trying to save money may forgo frequent oil changes, just to find out later that the damage this neglect may cause is very time consuming and expensive.
Loss of oil pressure, lower fuel economy, and a build up of engine sludge are just some of the problems that can result from a lack of regular oil changes. These are problems that may not sound too terrible by themselves, but that can lead to other automobile problems that can be so major that complete engine replacement is required. This is because running dirty oil through your engine is harmful to so many of its working parts.
The bottom line is that getting oil changes as recommended by the automobile dealer or manufacturer will save a lot of problems in the future.
