Ok.. Ok.. I know what you are thinking -that's insane I would never let my oil go that long. Fine but let your oil go longer than 3000 miles. With the introduction of oil life monitors GM has been able to push oil changes as high as 12,000 miles. This is with conventional oil folks. Everyone knows that synthetic last longer and protect better. Is it really so hard to believe that a quality synthetic oil can go 25,000-35,000 miles Even back in 2005 the average oil change drain interval in Europe was 10,000 miles. Here is where people tend to get upset because they do not like being lied to and deceived. The same cars that are in Europe going 10,000 miles or more on oil changes are some of the same cars sold here in America with oil change recommendations of less miles.
Why do you think that is? Greed! Yes pure and simple greed -big oil is big money! Listen Mobil had a 25,000 mile oil back in the 1970's after Amsoil had one on the market! Shortly after the introduction of their so called new formula they stopped marketing it as a 25,000 mile drain interval oil, and then somewhere around 2005 came out with Mobil 1 Extended Performance with a 15,000 mile oil change interval. Where did this oil go that they had back in the '70's? They buried it to sell more oil for 30 plus years and get in good with car manufacturers. Do you think car manufacturers think Amsoil is a bad product? Or do you think Mobil has pushed there way in as factory fill by using money and marketing techniques? Mobil or any other oil manufacturer does not want to get on the bad side of the auto service industry. If Mobil was pushing 25,000 mile oil change intervals do you think that they would be the factory fill for some vehicles? Here is something to consider and take note of. The Mobil Extended Performance Warranty does not cover your car if it is under factory warranty. From my perspective I feel that Mobil does not want to get involved with the manufacturers if a claim were to be placed while using their oil. Also, this would hurt the service department at the dealerships that service these vehicles. They would see the customer much less and it in turn would hurt revenue. This would get Mobil on the bad side of the auto industry, so for now Mobil will not recommend a drain interval that is any higher then the info in your owners manual unless your car is out of warranty.
Here is another way of putting this into perspective. Lets say in 2011 GM came out with a new Corvette factory filled with Mobil 1, and the owners manual stated oil change intervals at 25,000 miles. Certainly most Corvette owners would not go this far on an oil change but Mobil would certainly provide an oil that meets the specifications of the manufacturer for this application. Nothing more nothing less! While this may not happen with GM I really do believe sometime in the near future a car manufacturer will push oil change recommendations to this level, and Mobil will be right there to claim their spot with some new product that meets these recommendation while they have had it all along.
You see big oil is not about go green or looking out for the best interest of the public. It is all about selling as much oil as you can PERIOD.
This kind of marketing an thinking has made big oil millions/billions of dollars over the past 30 years. This is called market timing - now that new car owner manuals have recommended oil changes much higher than 3000 miles Mobil has decided to unleash their awesome NEW Product.. Here is a direct quote from the Mobil 1 Extended Performance site "You've never seen an oil like this before. Mobil 1 Extended Performance is a high-endurance motor oil designed for longer service intervals"
If you are looking for a company that stands behind their products, and supports the people that get them to the marketplace consider Amsoil for all your lubricant needs.
