I started using mobil 1 synthetic in 2002 when I bought my new Monte Carlo and i drove that car to 300,000 miles then sold it and someone else is still driving it. I now have a Camaro SS and use it in that. The dealer told me it's what they use in Corvettes. I would never use anything else now. Also Sam's has some great prices on it.

I buy the 5 quart jug to change my oil. Then I use this oil to top off whenever I need it. It seems to have a good oil life my car is in great running condition over 200,000 miles. Rolded over its first hundred thousand over when I pulled in the driveway, I bought it used. 2014 Chevy Cruze, synthetic oil on every oil change.

keep your car longer and running better with the best. reduces heat and friction in the engine, easier start ups in winter, won't break down in summer's heat.more time between oil changes. advice, get an oil filter made for synthetic motor oil, it's worth it.

I’ve used Mobil 1 oil in all of my vehicles since 1978. Many of the vehicles were turbocharged, and while some were new, most were previously owned vehicles. All my oil changes were personally done by adhering to the manufacturer’s normal service mileage guidelines. I’m proud to say I never experienced any engine or turbo failures related to wear and tear, while using Mobil 1 oils. Additionally, I never experienced any oil seal leaks from using low viscosity synthetic Mobil 1 oils in my vehicles.

I've been using Mobil one for 25 years. It's fantastic. I had a Chevrolet 350 c.i. engine for almost 21 years It had 517,000 mi. on it when I got rid of it. The engine was still running strong. (mobil 1 from the 1st oil change) That's why I will always use it .

The delivery was very quick, but the delivery guy left the product infront of the door on the street and did not even call or ring the door bell. I was lucky, I was going out and found out my mobil oil was delivered on the street. Thats why I gave 4 star, otherwise I would have given them 5 star

How can you beat Mobile One Synthetic Motor Oil? ..... You can't ! It's the best out there!! Even printed on my oil fill cap for my Corvette, it says Mobile One ONLY. Although it is expensive, Sam's had a nice special on Black Friday for Fifteen Dollars off 6 quarts. That was perfect because m Corvette takes 6 quarts and it was due for a California Smog check. I received the 6 quarts shipped from a warehouse from the other side of the country in a timely manner. I changed my oil on the Corvette with this Mobile One 5w-30 and I went to get my car smog checked. The sniffer tube was placed in my exhaust pipe to measure the amount of burned and unburned pollutants my big engine Corvette was putting out. He was AMAZED that it was measurements equated to a brand new car. Certainly I have to give some credit to the type of motor oil that I consistently use. Thanks Sam's Club for the fifteen dollar discount with FREE Shipping right to my door at a time when I really needed this product.

Have to watch out for Walmart pricing, in the title it clearly says 1 Quart (Case of 6) but you are really actually only getting 1 quart. I know others who have gotten the case size but others including myself did not. I chatted with support they said it was a mistake on their website and only offered a partial refund. The 5 quart container is a much better deal anyways and if I had known that I was only receiving 6 quarts I wouldn't have even placed this order. I don't even really use Mobil 1 anymore because all of the other competition has caught up and are usually cheaper options. Mobil 1 is still an excellent oil but it's pricey when compared to the others that can do the same for less. Walmart support is so spotty with who you chat with, some have resolved the issue by having the remaining quarts shipped out but then others like myself are only offered a refund.

I purchased this a couple weeks ago to use in my personal truck. From day one I only used synthetic oil. That's what the dealer recommends. I trust Mobil 1 to keep it running smoothly. Since 2008 it never fails me yet. You really get what you pay for. And that's engine wear protection.

When I got to the store they were unable to fill this order due to a lack of inventory. The purchase was made for 4 cases of 6 qts, they attempted to give me 4 individual qts. They only had 5 individual qts on hand and no attempt was made to offer a substitute. Walmart fumbled this order badly and I wasted a trip to the store.
