Mobil Delvac 1 Transmission Fluid 75W-80  

Mobil Commercial Vehicle Lube, United States


Product Description

Mobil Delvac 1 Transmission Fluid 75W-80 is an extra high performance manual transmission lubricant engineered for the latest, European heavy duty manual transmissions used in light to severe duty on-highway commercial vehicles. This transmission lubricant is a synthetic blend of base oils and an advanced additive system with excellent shifting performance, low temperature fluidity and high temperature viscosity retention. Mobil Delvac 1 Transmission Fluid 75W-80 is formulated with extended performance reserve for applications requiring API GL-4 service and more specifically modern transmissions requiring ZF TE-ML 02L and/or MAN 341 Typ Z4 approvals which now supersedes ZF TE-ML 02D and MAN 341 Typ Z3.


Features and Benefits

Today's technology has vastly improved the performance capabilities of on highway vehicle load, speed, and control through innovative drivetrain designs. These designs have increased the requirements of lubricants to deliver a higher level of performance. For heavy duty manual transmissions, friction control, wear reduction, thermal stability, shear stability, rust and corrosion inhibition, and seal protection are features that must be optimally balanced to provide extended gear and synchronizer life, smooth shift control, and high load capability over a wide range of applications. Mobil Delvac 1 Transmission Fluid 75W-80 delivers exceptional performance in current as well as older model manual transmissions. The key benefits include:

Features Advantages and Potential Benefits
Excellent load carrying, anti-wear, and extreme pressure performance Helps to protect against wear under harsh operating conditions throughout the transmission life
Excellent protection against deposit and lacquer formation Contributes to long seal life, and to extended drain and service intervals
Excellent protection from corrosion of copper and its alloys Helps to protect and to extend the life of synchronisers while delivering smoother shifting performance
Effective thermal and oxidation protection at high operating temperatures Contributes to extended drain and service intervals for controlled maintenance costs
Excellent shear stability Helps to maintain effective viscosity and film strength for wear protection during severe operation
Outstanding low-temperature fluidity Contributes to easy and smooth shifting, and quick starts
Extended service capability Helps to control operating costs and contribute to productivity
