The 5 cases were shipped separately. The first shipment with 3 cases had 2 cases leaking and the second shipment with 2 cases were fine. Due to the company policy, online orders can only be returned. It would have been convenient to just exchange them if the store have them in stock.

i always buy synthetic mobil oil for my cars and confident that I'm using quality oil. I'm doing the oil change myself to save money (and walmart sells it much cheaper than automotive stores) and to ensure it's done right. 0W-20 is for my 2011 car and i have a 1998 and 2001 both using 5W-30, both never had any engine issues, i'm always using mobil synthetic.

If your car doesn’t leak oil and you change the oil every 5k miles you can get to 200 k miles. I have done it using this product in cars and 1/2 ton trucks. If your car leaks go with the cheap stuff. This stuff is expensive, but because of my experience with vehicles lasting longer, I pay it.

The Price was Right! My vehicle requires eight quarts of oil for an oil change. Comparing prices for Mobile One oil on the net, this came in hands down in first place. Couple that with the first class curb service, why even bother looking elsewhere!

Mobil 1 synthetic is good oil for quick changes it is affordable and does the job. It is best for my vehicles since I perform oil changes every 5k miles. I used to buy the expensive kind which lasts 10k miles but I would rather buy a less expensive oil and have my oil change more frequent. Mobil 1 fills in this need.

Started using Mobile 1 in a new 2005 CRV at the first oil change. Changed the oil and filter ever year. Sometimes with 8K on the oil. Sometimes 12K. I did the 100K plug change and checked the valve lash. The plugs could probably last 200K. What was very impressive was the valve lash was within 0.001 of being in tolerance. The cam chain guides had no wear and timing chain marks were dead on. The inside of the valve cover was clean and looked new other then some slight yellow heat stains. Beyond belief. Been doing all my own work since the 60s. I know what is impressive.

I use Mobil products in all my vehicles, power equipment, and motorcycle. They've never let me down. As a diesel tech with over 20 years experience and having been born and raised in the trucking industry, I've seen many things. Everything that I've ever worked on which ran Mobil products faired far better than other brands. This is why I trust Mobil and use nothing but. To the public that reads this, rest assured this an HONEST review. There's no pay off or anything of the sort. Thank you Mobil for all the hard work and dedication to a great product!!

Mobil 1 is always my favorite brand for oil change. I have no complaint about this brand. I love placing online orders with Sam’s Club since they always pack stuffs and deliver them carefully whether the stuffs are light or heavy. Please keep up with your good work.

The 0W-20 oil I use in both a naturally aspirated four cylinder and a turbocharged four cylinder engines. The manufacturer recommends the 0W-20 synthetic motor oil. At over 120,000 miles, the naturally aspirated four cylinder engine burns NO oil and remains at above the "add" mark for over 7,500 miles. The turbo four has less than 50,000 miles and does not burn oil. the average MPG is above the manuracturer's claim. cannot recommend highly enough,

I use Mobil in all of my vehicles, been using Mobil full synthetic for about 14 years in one of my vehicles and haven't ever had a problem. I use several different weights depending on what vehicle, my oldest vehicle is from 1986 and the top end is clean with zero sludge. I change my oil at 5K even if the manufacturer recommends 10K intervals, oil claims to last that long but it's my personal preference to not take any chances on the life blood of my engines just to save a few bucks a year.
