- Performs well in older diesel engines, especially those that consume a lot of oil.

- Well-designed pour spout with a lid makes it easy to handle and prevents leaks.

## Cons
- Not recommended for trucks with oil-actuated injectors, like the 6.0 PSD engines, due to potential risk of injector failure.
- Contains lower ZDDP levels compared to older formulations, which may impact wear protection in some engines.
- Users concerned about long-term engine longevity might prefer oils from more trusted brands like Shell Rotella-T6.
- Limited to purchasing only 3 gallons at a time, which is inconvenient for vehicles requiring large quantities (e.g., 12 gallons).
- The need to buy multiple small quantities can be frustrating for those doing serious or frequent oil changes.
- Provides reliable basic performance but lacks extra features found in some premium synthetic oils.

## Bottom Line

Mobil 1 112786 15W-40 Delvac 1300 Super Motor Oil is a solid choice if you need a dependable, standard oil for older diesel engines that consume more oil and want to maintain equipment specs without synthetic additives. It's user-friendly with its pour spout and reduces engine noise noticeably. However, if your vehicle relies on oil-actuated injectors or you are particularly concerned about engine longevity, you might want to consider alternatives like Shell Rotella-T6. Also, if you require large volumes regularly, this product’s limited purchase size could be inconvenient. For dependable diesel motor oil in smaller quantities, this fits the bill well.
