Mike, using an aftermarket filter is inherently risky in ways that the Toyota engineers understand, but the lay public does not. Here's a real life example of what happened to a Toyota Supra owner who used the Purolator Pure One filter: http://i85.photobucket.com/albums/k75/4af/supra.jpg
This tragedy wouldn't have happened if the Supra owner had used the Toyota 90916-YZZG1 oil filter because it has a 23% thicker and heavier steel casing. Ironically, Purolator actually makes the Toyota 90916-YZZG1, but Toyota required Purolator to build it with a 23% thicker shell compared to ordinary Purolator filters. Toyota also required Purolator to make other changes like building the Toyota filter with an extra durable acrylic O-ring type filter seal that can better withstand engine heat and won't stick to the engine block (and interfere with the sealing capability of a new replacement filter) when the old filter is removed.
Read this carefully everyone... Do yu see what/whom I see?
Maybe yu do!
I am not the lay public. Are yu?
