Our synthetic blend beats the competition
We tested our synthetic blend against two of our competitors’ synthetic blends. The results? Mobil Delvac™ 1300 Super synthetic blend diesel engine oil prevailed, delivering more wear protection in industry wear tests.
More wear protection in every bottle
Mobil Delvac 1300 Super oils feature a carefully tailored formulation that provides better wear protection than some of our competitors’ synthetic blends. In a series of eight API CK-4 industry wear tests:
- Mobil Delvac 1300 Super 10W-30 synthetic blend oil exceeded CK-4 wear requirements by 50%
- Shell Rotella T5 10W-30 synthetic blend oil exceeded CK-4 wear requirements by 44%

Excellent wear protection + Fuel economy potential
Although the benefits of low viscosity oils are becoming more well-known in the trucking industry, some fleet owners still worry that they’ll sacrifice wear protection for fuel economy potential. Now they can get both from a low viscosity oil. When comparing the Mack T-12 top ring mass loss measurement versus the API CJ-4 passing requirement:
- Mobil Delvac™ 1300 Super 10W-30 synthetic blend oil exceeded CJ-4 wear requirements by 72%
- Chevron Delo 400 XLE 15W-40 synthetic blend oil exceeded CJ-4 wear requirements by 68%

And Mobil Delvac 1300 Super diesel engine oils deliver more wear protection than competitors’ synthetic blends.
