I'll protect my wallet by not having to rebuild my engine. I'll protect the environment by keeping the engine more in tune by changing the oil more frequently and being rewarded with an engine that lasts longer(less resources wasted on rebuild), an engine that performs better(less wasted fuel resources),..................... I beginning to believe that enviroweenies need to think things out a little more. Did the engineers do anything besides a UOA? Great, the OEM engineers did some UOAs. But, did they check the filters? Where is the used filter analysis? UFAs? Did they monitor engine time? Did they monitor fuel used? Will they be willing to share their formulas for the so called OCI idiot light reminders? Did they log the engine compression #'s over 150k miles of normal driving(not test stands), with about 5000hrs of running time, or with about 10,000 gallons of fuel used? Did they take pictures of the sludge building up in the engine over the time period? Did they perform regular leakdowns test? Where are the back to back or side by side comparisons? Just a UOA. I'd also like to see a larger sump, a standard oil cooler(water or thermostat air types), a larger filter, an engine timer, a fuel usage meter........, along with the UOA, prior to even considering an OCI. Like an odometer, the engine timer/fuel meter should also be tamper proof! So, whats the warranty like in these new cars? As BMW said, we'll lower the initial cost of ownership with extended maintenance schedules. I'd think that most people, in certain income brackets, trade up more frequently than the workers who buy cars that hopefully their kids or grandkids might be driving. I guess that if you always rebuy prior to warranty expiration, then why bother with any maintenance! I also now know why I'll never buy used. I'd rather have a new Ford/GM/Chrysler over the used luxury import. How many automakers/dealers have included free maintenance or sold packages with their vehicles? and seen sales increase? I bet that longer maintenance intervals might sway certain poorly researched individuals between brands.
