I gave my 09 Altima to my daughter for a work car. Sheās a physicians assistant and drives 150 miles round trip 4-6 days a week. The last several oil changes have been with clearance idemitsu 5-30 from auto zone. She showed up yesterday and I was shocked to see that she had almost 9k on the oil. I had some clearance TSC truck and suv that says ā10kā guaranteed so thatās what went in along with an old school fram ultra. She was a half qt down in a car thatās never used a drop. I love my daughter more than life, but the maintenance light along with low tire lights, and any other light is something that doesnāt faze her. She just motors on. I set the oil minder for 7500 and sent her on her way. We shall see how this holds up. Iām working my way through all my clearance purchases or Iād have gone with Schaeffers, EP or hpl for some added security. Surprisingly the oil came out still somewhat clean. When I owned the car it was serviced religiously every 4-5k.
