Talk to your parts counter or order on Amazon. You can find it pretty regular for $110/case. My parts counter guy swings between $95-120 depending on how much they're holding that month. Or go with Valvoline like smjYour gut tells you OE fluid is best, and really you can’t go wrong using it. However, I think the cost of the Nissan fluid is something crazy like $15 a quart. That’s at the point where it’s not just paying more - but getting hosed
I’ve been through this with my BMW - paying crazy high prices for OE fluids. Then I just got tired of paying & switched to aftermarket (but correct) fluids. They cost 1/2 the price or less.
I don’t mind paying more - but I don’t like to get hosed. I used the Castrol import trans fluid in my 01 Pathfinder & will likely use it in my Pro4X.
For oil I use Mobil 1 ES or Castrol synthetic if Walmart doesn’t have the Mobil. Mobil 1 oil filters & will use their differential fluid as well.
Never have a seen or heard of anything failing from using the correct high quality aftermarket fluids. The problem comes in when people use the wrong fluid.
