I requested an oil test kit today from Blackstone. I am curious how my 2013 Pathfinder w/ 3.5VQ engine is holding up on a longer OCI. Nissan recommends under normal conditions 7500/6 months, I am just over 6k miles at just over 6 months. Last service was done by dealer using M1 5w30 and OEM filter. A new air filter (oem) was also installed at that time. Vehicle has just over 21k miles. I am anxious as to see how it fairs as I have never ran a vehicle this many miles on a single OC.
