Only oil that I use in my car for some years now. Never any problems and keeps my car running great summer or winter.

Great product - have been using on all our cars for years and have not had any problems. Will continue to use it.

[This review was collected as part of a promotion.] Mobile 1 synthetic oil is the absolute best in quality for my vehicle.

Mobil 1 Adv Full Synthetic was one of the top oils recommended for my 24 F150 3.5 Ecoboost and U can’t beat Walmart’s price.

Excellent oil and is sold at a good price. Makes my cars run smooth. My store is always out of it. So, I haven't purchased any in months.

I always use Mobil 1 in all of my European cars and have for years. My cars all run great for over 150,000 miles!

Been using Mobil 1 for 20 plus years never no problems no fuming break downs use it in my cars and motorcycles

I have been using Mobile 1 since the 1970’s. Knock on wood. I have never needed an engine repair because of oil related issues.

With the instant savings the price was the best in town. I got 6 quarts cheaper then I could have gotten 5 quarts anywhere else.

THE OIL I ORDERED WASNT SECURE AND WAS LEAKING OUT OF THE BOTTLE..LUCKILY, IT WAS IN PLASTIC BUT WHAT A MESS..
