Engine oil Mobil or PENNZOIL

Just switched to Mobil1 from using whatever the dealer uses and my car runs so much smoother. Mobil1 from here on out.

Mobil 1 FS is the absolute best you can give your car, in my humble opinion, but any modern fully synthetic will be more than enough.

5-30 mobile one. Thats the only brand of oil I let touch my cars.

At the very least, make sure you're using quality oil like Mobil or Castrol or Pennzoil.

Personally I do 10k miles with Mobil 1 high mileage and a Walmart Supertech filter on all my vehicles and they're all well over 300k miles with no oil-related issues.

I would choose Mobil 1 Extended Performance if you're going with Mobil 1. It has the best addative package of the bunch. It's what I run because a 5Qt jug is $28 or less at Walmart.

I use Mobil 1 extended performance oil just to get that extra protection for a mere $3 premium compared to regular Mobil 1.

Mobil 1 FS is what I use on every car/motorcycle I’ve ever owned. Never let me down

Up the weight of the oil and get rid of that mobil 1 water

So I used Mobil 1 Euro FS 0w-40 in a 2025 Nissan Armada Pro-4x that has a 3.5L V6 twin turbo engine. I ran it for 2,000 miles and then sent in a used oil sample for analysis. I was surprised that highly touted Euro oil with all its various manufacturers spec had sheared outnof grade to a thinner 30 weight oil in only 2,000 miles.
