Sorry, I haven't posted lately. I have been busy with a full time job, starting my money coaching business and had a friend visiting from out of town last week.
Trent at The Simple Dollar has an article about checking how often you have to do maintenance on certain things. The usual standard for changing oil in your car was 3,000 miles. Now some cars can go longer between changes. I have put 3,000 miles on my car since buying it and it shows 47% oil life left. So if you have to do it less, you save money on less oil changes.
