Hy there you guy´s...
I´m speaking from Portugal and i have one question and would like to know if you could help me to awnser.
I´ve seen recently a documentary about the auto industry in America (amazing tale by the way) and there was a mention to this veihucle that was a V8 engine that would work only in four cilinders for economy sake and the most amazing thing was that it didn´t needed to change oil for life.
First. I wonder if its true. Then, does anyone know the model? Can you inform me where could I search for more information? As a simple student I´m trying to impress a teacher whith this information.
I would like to thank you in advance for the trouble and would love for some more info. Anything at all.

See you soon...

300C and i think cadillac had one too that shut 4 cyl. off

many v8 engines use some version of the Multiple Displacement System (http://www.google.com/search?num=20&hl=en&safe=off&rls=com.microsoft:en-US&sa=X&oi=spell&resnum=0&ct=result&cd=1&q=multiple+displacement+system&spell=1). The name might be slightly different depending on the manufacturer (some use the word variable instead of multiple).

I have NEVER heard of a vehicular engine that requires no oil changes for life! See this link (http://www.nordicgroup.us/oil.htm) for Motor Oil information.

Hope that helped.
