That's what a lot of owners use and it's recommended by Gurued Gear.
My recommendation would be 2500 - 3000 miles in between engine oil, shaft oil every other engine oil change.
So you are recommending to change the shaft oil every other oil change (the final drive oil) ? The owners manual...
I don't mean to hijack the thread, but does the guru flash help or hurt fuel mileage? 100mi trip is typically what I got before the flash and was wondering if I'd have to plan more gas stops in or not
