Does anyone know if Nissan uses the same brand of oil at all their service locations? just curious as I have a 03 Max and took my car for 3 oil changes - all at different Nissan service locations b/c of logistical reasons...if all Nissan service locations use a different brand of oil, will this harm my car in the long term?

Thanks,

 

Why don't you just tell them to put in the same type of oil each time? You don't know if their putting in 5w-30 or 10w-30? Synthetic or non.
