If you knew what you were talking about, I would be mad at you for making the ridiculous statements above. Conventional oil breaks down within 3,000 miles under average driving conditions. Synthetic within 5,000 miles. I own quick lubes. I change my oil every 3,000 miles and use full synthetic (would I do this if it wasn't good for my engine?).
You are in a losing proposition recommending 3,000 mile drain intervals. That goes back to the 1960's and it's 2009 now. Oils and engines have come a long way since 1960. If you keep insisting on recommending 3,000 mile drain intervals to your customers, you are clinging to a very out of date recommendation which is not providing very good customer service to your customers. They don't like you recommending oil drain intervals that conflict with their vehicle manufacturers recommendations and line your pockets with their money. Further, you are doing busy work by recommending 3,000 mile oil drain intervals, tossing out perfectly good oil, creating an extreme burden on the environment and making poor business decisions. You could be making more money and servicing more cars by recommending the oil drain intervals that vehicle manufacturers recommend. Nothing on a car wears out or needs replacing in only 3,000 miles. You're not making any more money recommending 3,000 mile drain intervals and if you persist in recommending oil drain intervals that fly in the face of vehicle manufacturer recommendations, you are going to be going out of business.
I have been in the automotive repair and maintenance industry for 25 years. I have done scads of oil analysis tests on my own vehicles and my customers vehicles that clearly show it isn't necessary to change the engine oil every 3,000 miles. This finding is supported by industry experts -
Ford Motor Company engineers recommend 7,500 mile oil drain intervals in their 2007+ vehicles. With the Dodge Challenger, Dodge engineers are recommending 6,000 mile drain intervals. GM engineers recommend following the oil change light with their vehicles and according to GM, the typical drain interval for vehicles equipped with their Oil Life System is 8,500 miles. BMW engineers recommend 12,000 mile oil drain intervals.
So you are actually saying that all these highly trained automotive engineers are wrong and you are right? You have a vested interest recommending 3,000 mile oil drain intervals, that fly in the face of these engineers recommendations, don't you? Interesting.
Here are some links and quotes from industry experts that prove without a shadow of a doubt that recommending the 3,000 mile oil drain interval scheme is only lining the pockets of quick lube owners and ripping off consumers -
3,000-Mile Oil Change Comes Under Fire
AMSOIL Applauded for Extended Drain Technology
"In Europe the average engine oil drain interval for current gasoline-fueled cars is about 10,000 miles," explains McFall. "In the United States, indicates the Automotive Oil Change Association, the average drain interval followed by most drivers is somewhat less than 5,000 miles—one-half of Europe's".
"Every year in the United States, this too-short drain interval results in the unneeded production of 300 million to 400 million gallons of engine oil; excess consumer expenditures of around $1.5 billion; and tens of millions of unnecessary oil changes."
"Not only are these unnecessary oil changes an expense to consumers, explains McFall, but they have an environmental cost as well. "The added environmental cost of having an average 5,000-mile oil drain interval (instead of 10,000 miles, as in Europe) may be nearly 100 million gallons of engine oil being dumped, untreated, into the U.S. environment annually."

AMSOIL Tech Article - Oil Drain Intervals On The Rise
"General Motors is actively seeking to extend oil drain intervals even further. In fact, the company recently asserted that 20,000 mile oil drain intervals are possible with existing engine technology and synthetic oils meeting current specifications, while 30,000 mile oil change intervals are achievable with appropriate motor oil quality and minor engine modifications".
Your vested interest 3,000 mile oil drain interval belongs on the ash heap of history my friend. Get with the times or you will be out of business eventually. Times are changing and you either change with them, or you will be buried by them. Don't be like a frog in a pot of increasingly hot water, never getting out and eventually dying.
