Mobil Delvac 1™ ESP 5W-30

High Performance Advanced Synthetic Formula Low Ash Diesel Engine Oil

Mobil Delvac 1™  ESP 5W-30 is an advanced synthetic heavy duty diesel engine oil for long and reliable service. The development of this product summarizes more than 90 years of ExxonMobil's research and development knowledge. The goal was to define a product that addresses all features required with modern on-highway truck applications, including those with emission control systems1. This top performance product offers unsurpassed oxidation stability3 which results in engine cleanliness promoting efficient and smooth engine operation. The robustness of Mobil Delvac 1™  ESP 5W-30 meets or exceeds the longest oil drain intervals defined by major global manufacturers, offering protection during extended oil drains up to 100,000 miles1. It was also developed and tested to protect the engine with the use of biofuel components to consider different diesel fuel qualities and future, sustainability related fuel components. The advanced lubricant formulation helps to gain fuel economy benefits in modern engine applications2. The outstanding wear protection performance of Mobil Delvac 1 ESP 5W-30 is the result of extensive and close cooperative development work of ExxonMobil with major equipment builders. As a result, this product meets or exceeds the requirements of the latest API and ACEA industry specifications for diesel engine oils, as well as the requirements of many major American, and European engine manufacturers.

Mobil Delvac 1™ ESP 5W-30 is an outstanding lubricant solution for modern and latest engine technology equipped with emission After-Treatment devices. It was developed by ExxonMobil to maintain unsurpassed oxidation stability performance to meet long oil drain intervals and support low maintenance efforts. Mobil Delvac 1™ ESP 5W-30 keeps at the same time critical and hot engine parts clean, also while bio diesel fuel components are used, for long and efficient engine life. This feature, in combination with the sophisticated additive system, ensures exceptional engine wear performance and supports long engine life. The low ash formulation protects at the same time all exhaust after-treatment parts required to meet emissions regulations.

The key benefits of Mobil Delvac 1™ ESP 5W-30 include:

Features Advantages and Potential Benefits
Unsurpassed thermal and oxidation stability Prevention of deposits and smooth engine operation
Step out wear protection Reduced engine wear to promote long engine life
Bio fuel compatible Maintains engine cleanliness and protection with bio fuel components
