Excellent product, great price and availability

I have been using Mobil 1 oil in all my cars which I buy new and keep indefinitely (currently I own three - each with a different weight oil requirement). None of these vehicles has ever had an oil consumption problem and all are or have been over 100k miles with one over 200k. Furthermore, the engines have never needed major repair - just routine maintenance. So, besides personally confirming that Mobil 1 oil's reputation for quality is well-earned, I can comment on Walmart's contribution. I change my own oil and almost always go to Walmart to get it as it is regularly stocked and the price is usually the best I can find. I always adhere to the manufacturer's suggested oil change intervals, but do not change oil more frequently than that. I also use high quality filters - frequently the manufacturer's brand which are not generally available at Walmart. So, in general I recommend both the oil and getting it at Walmart.

Worth the money

I've been using Mobil 1 synthetic oil in my gasoline vehicles since before they made an extended version. Though it is an extended drain interval oil, I only went 6000 miles. I usually trade vehicles before 100,000 miles so I can't really tell if the oil made a difference. But, I've known several people who purchased my used vehicles and commented on the longevity achieved. Not all continued my brand of oil but, it must have played a part in the long lasting engines.

Outstanding High Performance Full Synthetic Oil!

Mobil 1 Extended Performance Full Synthetic Motor Oil 5W-30 is a Top Tier Full Synthetic Motor Oil. First Class Product with a track record second to none. I feel very confident using this oil on my 2012 Subaru Impreza 4 doors Sedan. The overall performance of the engine has improved, engine stays clean, and helps reduce any oil consumption. Plus, protects the engine from the extremely high temperatures during the summer time in Phoenix, AZ.
