DEXOS VS GF-5 LUBE STANDARD

It looks like the automakers(GM) are going to be leading the way and setting the motor oil standards in the near future,rather than Big oil setting the standard. This is how it's been done in Europe for many years now.

The DEXOS motor oil standard will be superior to the New GF-5 standard making Dexos similar to the European motor oil standards, and it's about time!

This is a quote from one of the links that shows how good this new standard will be even over the GF-5 stanard.

<<<<The final Dexos standard has characteristics of a European formulation; improved oil robustness to support extended drain intervals with no improvements to fuel economy. In fact, Dexos requirements will incorporate a number of European performance tests (ACEA) that are not applicable in GF-4 or GF-5 standards. Dexos’ final formulation is considered more robust than GF-4 and new GF-5 standards. This is in contrast to one of the key elements of the proposed GF-5 standard, improved fuel economy. GM called for improvements in oil robustness and extended service intervals to support their vehicle’s Oil Life Monitoring System (OLMS) and to require fewer lifetime service visits. Upon the successful implementation of Dexos, GM will likely recalibrate the algorithm on OLMS to further extend intervals, as was done with the introduction of GF-4.>>>>
