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.

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.

This is all we use

This is all we use in our diesel trucks. Works well and no issues with our engine. Since we only drive diesel trucks, we go through a lot of this oil.
