Use Mobil 1 because of a discussion I had with my brother. He tears down high mileage engines as part of his durability validation. He told me that of all the engines he has torn down Mobil 1 engines look like new after the durability test. Other oils are good but snow some wear and tear.

My car needed 1 quart and I put it in. I haven't had any lights to come back on to say I needed 1/4 boil in my car it did the job I have a volleyball bowl and the light kept coming on saying I needed one quarter ball. I purchased this oil and is done the job. I would recommend it.

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.

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.

My local club doesn't carry Mobil 1 so when I see it on sale online I snap it up. I've been using Mobil 1 and changing my own oil since I purchased my 2003 Toyota 4Runner new, and it is my daily driver 15 years and 367,000 miles later. The 0W-20 oil is for my 2013 Toyota Avalon Limited. It is the manufacturer recommended weight of oil. Watch carefully and catch this oil on sale, and you have the best oil out there for a great price.

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.

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.

My '13 Acura RDX gets up to 32 mpg on the highway with Mobil1 Advanced Fuel Economy full synthetic oil, SAE 0W-20. And even with 193,000 miles on the SUV now, I don't need to add oil between changes when the maintenance minder comes on at 5-6,000 miles. Very happy with your full synthetic oil.

I wish the price was better. You can buy 6 quarts in a box at Costco for $19.99 I paid $25.00 plus Tax for 5 quarts of oil and 8.00 dollars plus Tax for just 1 quart of oil. I thought Walmart would do better for the customer regardless of how the customer acts. This is how Costco is thriving and setting better standards than a lot of other company’s out there for there Members. Please do better.

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.
