How The 3,000 Mile Oil Change Is Killing Your Engine
The 3,000 mile oil change is killing your engine! Every you change your oil, you increase your engines wear for the first few thousand miles!
It’s hard to convince anyone that 3,000 mile oil change intervals are outdated and may actually harm your vehicle more than it helps. This is why my goal is to convince you that you are causing irreversible harm to your engine every time you change your oil.
Rubbish you claim, but lets look at SAE report (SAE Technical Paper 2003-01-3119) from a joint study by Ford and Conoco:
“While evaluating engine oils in a prior study, we found that the valve-train wear improved markedly as the oil aged. Changes in tribological performance were linked to differences in surface film chemistry on the valve tappet components.” See SAE Technical Paper 2003-01-3119
Therefore, changing your engine oil too often accelerates engine wear. Not only are you causing more engine wear, but you are also wasting your money.
In fact, most newer vehicles are suggesting oil change intervals between 5k and 7k miles. Some oil manufacturers have oil that can last up to 25,000 miles! So how often should you change your oil?
Let’s take a look at another example. Here is a used oil analysis from my own vehicle.
As you can see from my very own testing, wear increased early one and started to taper off as more miles were accumulated on the oil. After the first 2,000 miles, the iron jumped up to 10 ppm. After another 2,000 miles, it stayed at 10 ppm. The other wear metals show similar trends.
Each vehicle is different, and every engine is different. How long you can go between oil changes depends on your specific engine.
Of course everyone likes to have a specific number of miles you can drive safely between oil changes, and if you like to know when to change your oil, you are in luck. If you would like to now how long your specific oil will last in your specific engine, get a used oil analysis.
A used oil analysis will let you know how long you should go between oil changes for your specific vehicle and engine oil. It’s very easy to do, simply take a sample from your vehicle and send it in for an analysis. This will give you a sure fire information regarding your engine oils condition at the time the sample is taken. In addition, it will also tell you if you have any other problems with your vehicle.
So if you are tired of having to change your oil ever 3k miles, or you think it’s beneficial to change your oil so often, I hope this small article has opened your eyes to the truth.
