I've owned several Toyotas over the years and usually use the oem filters as they are fairly inexpensive. About $4 a piece. Anybody (I am sure there is) know if these filters are worth using or am I wasting my $$ and engines by doing so?? Thinking about using Wix and Castrol Edge 0W-20 when the 2 year service program is over. Just bought a new 17 Highlander. Thanks
