Preferred over any other brand

Use in my semi for years. Prefer Mobil to be used in my heavy trucks as well as my personal cars. Mobil is cleaner oil and my semi use to leak using Rotella oil. When started to use Mobil Delvac I have no issues of leaking or nor have to add to oil between oil changes.

Delvac oil

I prefer this oil for my recently purchased diesel truck. It's a 1996 F-350 turbo powerstroke and has 345,000 miles, so a long engine life oil is important to me. It holds 15 quarts so it's great, and makes sense, to buy it in the 5 gallon buckets. I will continue to use it and was also recommended by my son.

Terrible sight gauge on container.

I dislike the container. Very difficult to see how much oil is left over when trying to pour out a specific amount. Please make it so you can see amount remaining when using partial amount of oil.
