Passenger Car Motor Oils – Past, Present, and Future

Passenger car motor oils have changed dramatically over the last 10 years. Gone are the days of 5W-30 and 5W-20 for most vehicles.  Due to the increase demands on engines, EPA mandated fuel economy increases and other requirements; the need for different viscosity motor oils has been required.

In 2011 General Motors introduced DEXOS motor oils.   DEXOS oils were API approved GF-5 oils that could be used in other makes of vehicles requiring 5W-30 or 5W-20 motor oil.  But GM preferred the DEXOS products for their vehicles.  DEXOS was only available at GM dealers. If DEXOS was not available then GF-5 approved oil could be used for the oil change if the customer did not elect to go to the dealer.  Since this time DEXOS has been licensed to all the major oil companies and blenders of private label brands.  DEXOS is available at most quick oil facilities and repair shops.

Currently we have 6 types of 5W-30 motor oil.   Conventional, Synthetic Blend, Full Synthetic, Dexos and High Mileage all GF-5 approved.  There is a Euro 5W-30 for Mercedes, BMW and VW,

We also have 5W-40 for diesel powered Euro vehicles.

In 2017 we will be changing to a GF-6 which is designed for better fuel economy, improve wear protection for the engine as a few benefits for this new standard. But with this change in specification brings more types of viscosity oils to meet the requirements from the automobile manufactures.  Go to www.oronite.com/products/gf6 for more information on the new specifications.

In closing with all the changes and oils out there, it is even more important to follow the owner’s manual recommendations for the correct oil for your vehicle. For questions or more information, contact John Rang at john.rang@jos.us.com or 317-502-6268.
