Mobil 1 Extended Performance Full Synthetic Motor Oil 0W-20, 5 Quart

This oil is extremely well rounded and worth the extra cost over almost all other synthetics. It is a fair deal at Walmart for 28.68$ / 5qt jug however, I wouldn't pay 10$ a quart for it at the local auto parts store. I have a 2012 Genesis Coupe 2.0T with 141,000 miles on it and counting. I have used this oil for the majority of oil changes, all of which I have performed myself. I live in northern ND and this vehicle faces extreme cold conditions for a quarter of the year. I have never run into any engine related problems the entire time I have owned this vehicle (bought it new#. I would never run this oil for 15,000 mile intervals being that it is a turbo engine however I have pushed it as far as 6400 miles with no problems. I have always been a loyal BP fuel customer and, as a result, have tried to convince myself to switch from this oil to Castrol Edge Extended Performance especially since Walmart now carries it in 5qt jugs for the same price. After a couple Castrol oil changes I have switched back to Mobil1. Although the Castrol held up fine, I can't help but feel like it is an inferior product to Mobil. After 5800 miles the Castrol poured out extremely thick and I do notice better fuel economy with Mobil1. I drive a lot and constantly monitor wind, temp, etc. and take this into account with fuel economy. I believe there is a good reason why Extended Performance Mobil is consistently selling out at both Walmarts around here. If your going to spend this much on an oil change, I would strongly suggest using this Mobil 1 Extended Performance oil and also a quality oil filter #Not a Fram, etc.) There is no point in using oil of this caliber with a 3-4 dollar filter. My only complaint about this product is the price of Mobil 1 E.P. oil has gone up significantly in the last year, I believe in early 2014, I could buy it for $25.17, then it went up around April/May to $27.97 and now, $28.68. If it goes up another $3.50 next year I will most likely consider something different. As comforting as it is to know I am using a product that will tolerate anything I would possibly put it through and then some, there are many other oils less expensive that can sufficiently protect my engine too. In the end, I recommend this product to anyone looking for a top notch oil. It is worth the extra 2$ investment over regular Mobil1 in my opinion and based on the research I have done online. If you are looking for a quality synthetic at Walmart, you will find most everything has a similar price. I would strongly advise choosing this motor oil over Pennzoil, Castrol, etc. based on my experience.

Mobil dropped the CE/CF designations from M1 15W-50. It used to be the best oil for Diesels. Now it is not fit for use in older Diesels. Mobil keeps changing the characteristics of M1, apparently to make it cheaper and less effective, and to make formulations for newer (post 07) engines. Finding a good synthetic for older Diesel engines is getting very difficult. Mobil would be better served to leave the formulation of established products alone, and use a new product name for new products. Diesel owners, BEWARE!
