We don't drive over-engineered OTR equipment made with quality components. Whats a decent car cost new compared to an 18-wheeler??
Preventive maintenance is what we have. 30k-50k change intervals every 2-3yrs is easy, cheap, and reasonable maintenance for any vehicle. All my fluids get dumped every 30k!!
If Ford, GM, Toyota.... would give me a 750k warranty, then I would abide by their rules. Cars are pretty much disposable and I plan on keeping mine as long as possible...2-4 times the distance/time of any lame automaker factory warranty.
My new Kia with my driving style/location, and with a 10/100k warranty, requires gear oil changes of 3yr/36k for the manual transmission, 15mo/15k transfer case, and 30m/30k rear end!
What does Kia know that the domestic automakers ignore?
