Want a site that has endless material on filters, oil, transmission fluid, coolant, cutting open filters, oil analysis results, etc.? Bob Is the Oil Guy There's even a sub forum for Motorcycles. Best of all, no moderators that hate oil threads, because everything to be known about oil was settled in 1957, and there is no longer anything to discuss.
That second link in case it wasn't working for you still
Same as links with outdated, obsolete information.
Could you give me the Cliff Notes? Castro GTX and FRAM filters my whole adult life.
Is it going to give cancer to my 169,000 mile Murano? Could it have given my GMC 2500 problems after 250,000 miles?
I'm sure Castro GTX is fine in your 4 wheeled, gas powered vehicles. Fram makes three grades of filters and based on the mileage on your vehicles whichever Fram you're using is doing a good job.
