European driving habits and secret behind it



53% of total fuel consumption is for journeys less than 10 km!
This could translated to not reached optimal operation temperature for motor oil for total half fuel consumed or 75% of all kilometres of the vehicle in its life span. In other words thinnest oils much better for cars with similar European driving habits.

Mercedes-Benz MB 229.52 Oils Fuel Saving Advantage

Mercedes-Benz MB 229.51 motor oils has to pass a fuel economy test which limited to at least 1.7% saving comparing to reference oil.
MB 229.52 motor oils sets this limit to 1% more comparing to MB 229.51 oils.
Using MB 229.52 means at least 2.7% fuel economy gain compare to reference oil RL191 SAE 15W40 which has HTHS 3.9 mPa. MB oils HTHS limit is minimum 3.5 mPa.
They also more resistance to oxidative thickening than MB 229.51 oils.
Approved Mercedes-Benz MB 229.52 oils can be found in below page:

Specification Comparison GF-5 vs GF-6A

Notable changes:

Piston cleanliness rate.
Engine sludge rate.
Oxidate thickening protection.
Turbo protection.
LSPI, new measures.
Fuel efficiency; avg. 1.9% in 6500 miles for GF-5 to avg. 2.9% in 10,000 miles for GF-6A



Second Generation dexos1™ has been delayed to January 2017

Second generation dexos1™ performance improvements specification includes:





  • Stochastic pre-ignition (SPI) prevention
  • Heightened fuel economy limits
  • Reduced turbocharger deposits
  • Additional testing to ensure durability and cleanliness 

  • Mandatory transition to the new dexos1 specification was expected in August 2016 before the news of delay; current dexos1 certification will expire at that time. We still expect some products to be approved and introduced during 2016, but timing is unclear. Oil marketers are urged to examine their existing product lines and licensing status and to investigate potential reformulation challenges with new chemistry.The latter is impacted by test availability and it is also likely that the complexity of the new specification is impacting delivery of programs.



    SAE 8 and SAE 12 Viscosity Grades

     On January 20, 2015 the Society of Automotive Engineers, better known by its acronym as SAE added two new viscosity grades to its most popular viscosity classification system defined under the SAE J 300 standard. The new viscosity grades are SAE 8 and SAE 12 defining new limits for future engine oils built for even better fuel economy.
     The low shear rate KV limits for SAE 8, SAE 12 and SAE 16 overlap to allow greater flexibility in lubricant design.


    These new viscosity grades allow the formulation and production of lubricants that enable better fuel economy. Honda was the first automaker to request the introduction of these new grades after having completed successful tests using oils with similar parameters. While these new viscosities certainly set the path for motor oil development for the time being you will not find any SAE 8 or SAE 12 oil on the shelves. And even when there will be actual products meeting these specs they will only be suitable for engines designed with these oils in mind. Other engines, including most older ones would not be well enough protected with these very thin oils.
