This question is in regard to my auto transmission remote filter which uses a regular oil filter. should I changed the filter based on mileage or time wise, I only drive about 8 miles a year, and worried if the filter is left to0 long it might disintegrate due to old age. ahouls I worry about that happening?? BTW this is on my 91 Pathfinder with 145k miles..thanks for any input, I'm currently using pure one and changing it yearly.
