The owner claims they would never do such a thing, but three years after Canyon Auto changed the engine coolant on my Toyota, my new mechanic says that my engine had been overheating because my previous mechanic (Canyon) had put improper Dexcool orange coolant in it, rather than simply the normal green coolant or the red or pink Toyota super long-life coolants.\r

My mechanic tells me that when he went to drain the coolant, it had actually turned into a thick, black, crystallized sludge to such an extent that he had to flush the coolant system not once, but twice, to get it all finally cleared out. \r
\r
Now I have an engine that loses about two quarts of oil every 4,000 miles, whereas it never did anything of the kind before, and I strongly believe it's because the bad coolant caused the engine to stay overheated so much that it dried and cracked the internal engine seals to the point where the oil (and possibly the engine coolant) now seeps into the internal combustion chamber, producing the unusually nasty exhaust smell I now get from the tailpipe.\r

Be careful with these guys.\r
