I have worked many years in the automotive field and this is one of the dirty little myths to increase profits. "Change your oil every 3000 miles."

This is crap and can cost you way more than you need to spend. You should change your oil between 5,000 to 7,500 miles. If you drive in very hot climates and a lot of stop and go city traffic, be sure to change it every 5,000 miles. If you drive highway miles, change it every 7,500 miles. This will save you money and the only winner at 3,000 is the oil companies and the repair shops.

God bless you I've been telling people this for years to deaf ears. I like now that they have these new oil formulas that are now rated to go more than 3k miles... I would bet the last remaining hair on top of my head that its "formula" is no different than their normal oil.

You are 100% right. When I managed a Good Year auto center, we often had training by major oil companies and one of the major oil suppliers told us that the cheapest store brand oil is no different than the highest price brand. In fact the only difference you will see is if you run your oil over 8,000 miles than you can see a little more break down in the cheaper brands.

We were instructed to tell all customers to change the oil every 3,000 but when I always told mine that they could change it every 5,000-7,500 miles. I guess my honesty payed off because I had one of the largest return customer base in our region.

I agree with you 100%! I usually change the oil on my mustang once every 2 years (Only because I only drive it about a thousand miles per year. On my other cars I change once a year.

I hope none of my customers hear of this, 76% of our productivity is 3,000 mile oil changes. Just Saturday I did an oil change on a brand new Rav 4 with almost 4,000 miles on it...

There is absolutely no reason to change oil at 3k. The oils have become so much better than what they were 20 years ago. The major compnents that break down are the additives, and most last much longer than 3k. It won't hurt if you drive more than 3k. Read your owners manual in most new cars, they say 4500-8000 miles for a service.
