I have yet to hear of any engine failing due to following the mfg recommended schedule. Most of the stuff mentioned in this thread regarding intervals is pure nonsense not supported by any auto maker or scientific evidence. In fact, studies support the idea of extended oil changes.
Urban legends, old wives tales, the grizzled geezer, oil forums, or whoever has been spreading this rubbish around for years. All of these oil changes are at best described as anal and a waste of precious resources.  |
And what scientific evidence have you presented to support your position?
So far all I see is heresay.
