Mobil ATF+4  

Mobil Passenger Vehicle Lube, United States

Semi-Synthetic Automatic Transmission Fluid

Product Description

Mobil ATF+4 is specially formulated to ensure optimal performance in Chrysler automatic transmissions. Its unique additive package provides the proper frictional properties, excellent low-temperature fluidity and dependable wear protection required in applications where a Chrysler MS-9602 type fluid is recommended.

Features and Benefits

The outstanding performance features of Mobil ATF+4 offer the following advantages in Chrysler applications:

  • Excellent flow properties at low start-up temperatures and high operating temperatures
  • Improved shift performance and vehicle driveability/improved shudder performance in Chrysler vehicles
  • Good viscosity stability
  • Excellent oxidation stability, less fluid breakdown in high-temperature service
  • Dependable protection against rust and corrosion
  • Provides more assured wear protection for maximum transmission/transaxle life


Mobil ATF +4 is recommended by ExxonMobil for use in these applications:

  • Automatic transmissions specially formulated for Chrysler vehicles, including Dodge, Plymouth, Eagle and certain Jeeps, that require a fluid meeting ATF+4 specification.
  • Mitsubishi and Hyundai applications where an MS-9602 type fluid is specified.
  • Services that specify a ATF+, ATF+2 and ATF+3 type fluid, including certain manual transmissions, transfer cases and power steering units (1999 and later).

Mobil ATF+4 is not recommended for vehicles that require Ford Mercon® or General Motors Dexron® type fluids.

Automatic transmissions should be checked for proper fluid levels at regular intervals, and the fluid should be changed at manufacturer-recommended intervals. However, this may vary due to your vehicle's operating conditions. Some manufacturers recommend more frequent changes of transmission fluid under severe driving conditions, such as heavy traffic, hot weather and trailer pulling.
