Are Oil Changes Really Necessary?
Well, if you don't mind, I'd like to take a little time to, first of all, prove that I'm not in need of psychiatric care. And secondly, I hope that you'll allow me to explain why I believe that a premium synthetic oil CAN last for 20,000 miles or more.

Motor Oil Breakdown What really Causes It?
Petroleum oil begins to break-down almost immediately. A high quality synthetic, on the other hand, can last for many thousands of miles without any significant reduction in performance or protection characteristics. Synthetics designed from the right combination of basestocks and additives can last almost indefinitely with the right filtration system.

What About Additive Depletion?
Many people swear by these "extra" Miracle Additives, but I am a firm believer in independent lab results. Every independent test I've seen regarding special oil additives such as those mentioned above has given no indication that they provide ANY measure of increased engine protection. In fact, in some cases

How Does Oil Contamination Occur?
Part of the problem is that traditional paper air filters do not fit all that snugly in the air intake compartment. They've improved, but they're still not great. More importantly, though, they let way too much debris shoot right through the filter element itself. As a side-note, they do not

Engine Wear Particles Cause Oil Contamination
One aspect that proves to be very important is cold weather starts. Now, all of us have heard about cold weather starts for years from oil additive manufacturers. We've all heard, Just put our additive in your crankcase and it will form an impenetrable layer over engine components that will

Combustion By-Product Cause Engine Damage
Poor ring seal allows combustion by-products to pass from the combustion chamber into the crankcase where they contaminate the oil. Tight ring seal keeps them out. Synthetic motor oils encourage a tighter ring seal than petroleum motor oils do.

Efficient Oil Filtration Recommend
The actual filtration efficiency of a particular filter really depends upon the filter manufacturer, and it is sometimes very difficult to get any specific numbers from them regarding their filters' actual filtration efficiency.

Synthetic Oils Offer Greatly Extended Drains
There are a couple of companies out there that are probably good for extended oil drain intervals. I'll speak more about the specific companies in the next chapter. However, since many people use Mobil 1 and believe it to be the best synthetic available (mainly because it is the most

Very Few Companies Offer Extended Oil Drains
Now, you may be saying to yourself, "This is all great, but there is something I just don't understand. If there are oils out there that will last for 25,000 miles - and have been for over 25 years - why am I still being told to change my oil
