European Motor Oil - Mobil Dexron VI Automatic Transmission Fluid

mobil dexron VI AUTOMATIC TRANSMISSION (ATF) FLUID

Mobil Dexron VI ATF is General Motors’ latest and most recent specification for General Motors vehicles. Like Dexron II and III before it, it is destined to be the ULTIMATE automatic transmission fluid worldwide. Dexron VI is BACKWARD COMPATIBLE with all previous General Motors Dexron specifications.

Mobil Dexron-VI ATF provides warranty protection for 2006 and newer GM vehicles. It should also be used for improved performance in 2005 and earlier GM vehicles, wherever DEXRON is specified. Mobil DEXRON-VI ATF is a high performance, synthetic blend automatic transmission fluid formulation designed to meet the stringent service fill requirements of GM’s Dexron-VI specification. ADVANTAGES OFFERED BY MOBIL DEXRON-VI ATF over EARLIER DEXRON/MERCON TYPE TRANSMISSION FLUIDSs:

Extended fluid life

Improved oxidation and thermal stability

Optimized frictional properties that provide smooth gear shifting during low temperature operation and help prevent transmission vibration

Outstanding resistance against sludge and deposit formation

Improved anti-wear protection which contributes to extended transmission life

Outstanding low temperature performance

Although DEXRON-VI was introduced into production starting with 2006 model year vehicles, there are still some misunderstandings about this ATF transmission fluid. Here are some facts to help you understand the introduction and use of Dexron VI transmission fluids. Since GM introduced specifications for automatic transmission fluid (ATF) in 1949, they have periodically upgraded specifications as part of their continuous improvement objectives. The upgrading process ensures that available ATF fluids are of an appropriate quality for use in transmissions that have been designed around the improved factory fill fluid performance.

Please Note, that as with their previous upgrades, DEXRON-VI fluids are designed to be backward compatible with earlier transmission hardware. Also noteworthy is the fact that earlier ATF fluids are NOT FORWARD COMPATIBLE with transmissions that were designed to use DEXRON-VI.

DEXRON-VI can be used in any proportion in past model vehicles equipped with an automatic transmission, in place of DEXRON-III (for instance, topping off the fluid in the event of a repair or fluid change). DEXRON-VI is also compatible with any former version of DEXRON for use in automatic transmissions. In fact, DEXRON-VI Automatic Transmission Fluid (ATF) is the only approved fluid for warranty repairs for GM transmissions requiring DEXRON-III or prior DEXRON transmission fluids.

TIP: Since some early bulletins were issued, further validation has taken place and certain transfer cases and manual transmissions now DO use DEXRON-VI, so it's important to refer to the owner manual for appropriate recommendations. All licenses for DEXRON-III expired at the end of 2006 and will not be renewed. Fluids sold in the market after that date bearing claims such as "suitable for use in DEXRON-III applications" or similar wording should be avoided, because 'DEXRON-III' fluids are no longer checked and policed by GM and therefore may not be the originally tested and approved formulation.

ADVANTAGES OF DEXRON-VI:
GM uses an ATF for factory fill that provides significantly improved performance in terms of friction durability, viscosity stability, aeration and foam control, and oxidation resistance. In addition, the fluid has the potential to enable improved fuel economy and extended drain intervals. The service fill specification for a fluid meeting these standards is designated as DEXRON-VI.

When compared with earlier automatic transmission fluids, DEXRON-VI offers these improvements and benefits:

enhanced performance of both new and older transmissions

longer ATF life (160,000 km/100,000 miles normal, or 80,000 km/50,000 miles severe). It is important to refer to the owner manual because certain vehicles recommend a normal service drain interval of 150,000 miles (240,000 km).

extended transmission life

Friction Stability (improved 100%). Friction describes how the fluid behaves when transmission clutches or bands are engaged. A fluid with poor friction characteristics leads to grabbing, chattering and slipping.
