I watched a 60 Minutes episode a few years back where Consumer Reports took 10 New York City taxi engines apart, inspected, photographed and documented engine wear then rebuilt the engines. They placed new motor oil in all 10 taxis. 5 taxis had oil changes every 3,000 miles or every 3 months for one year. The other 5 taxis also got new oil but went a year with no oil change, only weekly level checks and filled to proper level.
After the year was over all 10 of the engines were torn apart, reinspected and no difference was found in engine wear between the two groups.
Something to think about...
The most important thing of course is making sure your oil level is high. Most people think after putting in Amsoil is just run the car until you hit 20-30,000 miles. I'd check it at least once a week.
By the way I took some out tonight after having it the car for 2 weeks. Clear as when I put it in the car and still at the same level
