Mobil 1 44986 5W-40 Turbo Diesel Truck Synthetic Motor Oil - 1 Quart (Pack of 6)

Great diesel oil. It works great and has for approaching 200K miles. I wouldn't run anything else.

Have always used this oil in our Kubota tractor

This is my trusted brand for all my Equipment. I have never had an engine problem in over 38 years. I get great fuel mileage. No wear on my engines and smooth starting and running. I am a Loyal "Mobile 1 Synthetic Oil" Fan.

Probably the best oil you can use. I used it on my turbo diesel jeep wrangler. I am happy with it all arround great product. Keeps a healthy engine, stayed clean at end of the interval and did not burn, cooling is optimal, stays true to its mileage. Perfect product.

If you own a diesel pickup and want the best possible oil delivered at a good price this is your oil. I live in California and travel across country so I experience all temperature ranges. This oil has performed well in 115 degree heat as well as provided good starts at 10 below zero. Consumption is reduced and my fuel mileage tends to be a little better than most similar diesel trucks. I highly recomend this oil.

If you have a Ford Powerstroke 7.3-then you know about the cold weather "romp romp"idle. The injectors are oil driven, and cold oil gives you a poor idle until it warms up. I no longer have to plug my truck in when its cold, and it fires right up and idles perfect. This oil o=is so good I only change it twice a year- so it works out cheaper in the long run tha using conventional oil.

Always used Mobile 1 motor oil in my automobiles. I have 188,000 miles on my car and when i took it in for a recall the mechanic couldn't believe the condition of the motor as it is still like new with 188,000 miles. So when I bought my Ram 1500 with an Eco Diesel engine I used Mobile 1 Diesel engine oil. Runs fantastic, gets better mileage than my 4 cylinder car!

I have used Mobile 1 Synthetics for years and have always been very happy. I use this or Rotella T6 in my GMC Turbo Diesel. The problem here is that I can buy this or the Rotella at a significantly lower cost at my local Big Box Store. This creates the conundrum of cost here vs. cost of driving to pick it up. The disparity is too large.... Still will continue to use the synthetics wherever I find the best price.

I am using Mobil1 same grade oil since long time . the one I received has not be sealed. open bottle. could not confirm as genuine oil by comparing the viscosity and color of the oil with my left over original Mobil 1 oil. I do not recommend this business to others sorry about this
