> I use Royal Purple as well matched with an original Nissan filter…works great, my motor loves it. Actually, you can pretty much feel an increase in power with Royal Purple, it frees everything up and so far, from what I see has the best protection out of all other SYN oils I’ve tried. Exceptionally good on turbo motors.

i also use royal purple with oem nissan SR20det filter
