Mobil Delvac Synthetic Transmission Fluid 50 is a fully synthetic, manual transmission lubricant engineered to meet the most demanding extended drain and OEM warranty requirements. It is recommended for year-round lubrication of manual transmissions in light to severe duty on- and off-highway equipment operating in a wide range of environments. Designed to provide maximum protection and extended operating life to heavy duty transmissions, Mobil Delvac Synthetic Transmission Fluid 50 provides significant advantages over conventional sulphur-phosphorus gear oils, including outstanding high-temperature performance, oxidation stability, wear protection, and corrosion control.
It has the same viscosity as most SAE 50 engine oils and SAE 90 gear lubricants at the high end of the temperature-viscosity scale, and because of its inherently high viscosity index, it provides stronger film strength at higher temperatures than conventional oils. Mobil Delvac Synthetic Transmission Fluid 50 also ensures effective lubrication at below freezing temperatures without channelling.
The outstanding performance of this product is confirmed by its approval for heavy-duty transmissions covered by Eaton Roadranger and Extended Warranties of 750,000 miles, with oil drains of 500,000 miles. It is also approved by Mack against its TO-A Plus 500,000 mile extended service classification. Mobil Delvac Synthetic Transmission Fluid 50 meets or exceeds the requirements of the API service MT-1 EP gear oil service classification and is recommened by ExxonMobil for use in transmissions and gear cases where API Service GL-1 through GL-4 gear protection is required.
The performance capabilities of today's heavy-duty on- and off-highway equipment have vastly improved in terms of load, speed, control, and reliability through innovative powertrain designs. These designs have markedly increased the demands on transmission lubricants, requiring them to deliver higher levels of performance while extending drains. For heavy-duty transmissions, friction control, wear protection, thermal stability, shear stability, rust and corrosion protection, and seal protection are features that must be balanced to provide extended gear and synchroniser life, smooth shift control, improved efficiency, and higher load capability over a wide range of applications and operating environments. Mobil Delvac Synthetic Transmission Fluid 50 delivers unequalled performance in today's manual transmissions. The key benefits include:
|Features||Advantages and Potential Benefits|
|Excellent load carrying, anti-wear, and EP performance||Extends transmission life and reduces cost of operation|
|Outstanding protection against deposit formation||Longer seal life, extended drain and service intervals|
|Maximum protection from corrosion of copper and its alloys||Protects and extends the life of synchronizers|
|Optimized thermal and oxidation protection||Extends component life and improves efficiency|
|Exceptional shear stability||Minimizes wear during severe operation|
|Outstanding low-temperature fluidity||Reduces wear during cold temperatures and improves shifting with quicker starts|
|Extended drain and service interval capability||Provides lower operating costs and higher productivity|
|Improved friction reduction properties||Improves fuel economy and lowers operating costs|
