For many years, Mobil Delvac™ engine oils have helped construction contractors, agriculture professionals, landscapers and truckers achieve long engine
life in their vehicles. We offer a variety of formulations including conventional mineral oils, semi-synthetics and full synthetic. Learn more about
synthetics and the different protection and performance levels available.
Why use synthetic oil?
A synthetic lubricant contains more highly refined base oils than those used in conventional mineral oils, offering you additional protection and
Synthetic engine oil provides a variety of benefits that help keep your engine running at optimal performance.
To understand synthetic engine oils, let's look at the origins of engine oil. There are three basic types of lubricants available:
Conventional mineral oils, which are the traditional types
Semi-synthetics, which are a blend of conventional and synthetic types
Full synthetic lubricants, which are growing in popularity
Both types are made from crude oil that comes from the ground. The difference? Synthetic oil is made from more advanced refining processes and is higher in
purity and quality than conventional mineral oils. The refining processes not only remove more impurities from the crude oil but also enable individual
molecules in the oil to be tailored to the demands of modern engines. These customized molecules provide higher levels of protection and performance.
Synthetic oil performance is typically more robust, especially in terms of low-temperature pumpability and high-temperature stability, as well as providing
protection against deposits.
More benefits of synthetic diesel engine oil:
Excellent low-temperature flow performance
Mobil Delvac synthetic lubricants are engineered to reduce internal friction, which results in outstanding flow characteristics at low
Higher viscosity index translates to a more stable viscosity across a broad temperature range. Along with the outstanding low-temperature
performance, Mobil Delvac synthetic lubricants resist thinning at high temperatures. This means our Mobil Delvac synthetic lubricants provide exceptional
protection across a greater range of operating temperatures.
Improved oxidation and thermal stability
Improved oxidation stability and thermal stability in Mobil Delvac synthetic lubricants compared to conventional oils result in less viscosity
increase with age and better deposit control. That translates into the potential for extended oil drain intervals. Fewer oil changes and less downtime can
help save you time and money.
Excellent wear protection
Newer vehicles must be able to handle higher torque and increased shock loads. Compared to mineral oil-based drivetrain lubricants, Mobil Delvac synthetic drivetrain lubricants provide outstanding anti-scoring performance, which can help increase gear life at high speeds and under shock-loading conditions. Mobil Delvac 1™ ESP 5W-40 and Mobil Delvac™ 1 LE 5W-30 provide excellent wear protection.
