I searched and found inserted opinions on other threads but didnt see where the question was asked straight up so here I am.
Switched over to Mobile 1 5w-30 last oil change, with 5K on that, changed oil again, new filter but added Lucas Synthetic Oil Stabilizer to Mobile 1. Now Lucas claims their product "Increases oil life atleast 50%."
With that said, how long would you go before your next change ?
Conditions my truck performs in is 11 mile daily trip to work, hour drive to hunting club every weekend and a couple minutes of locking into 4x4 down a hunting road. No towing or heavy loads. Is 10K too long ? Can I go further safely ?
