Duragard® Diamond Plate® dexos1 100% SYNTHETIC SAE 5W-30 is a full synthetic formulation using the most advanced additive technology available to meet the latest fuel economy standards while exceeding the specifications for wear control, piston deposits, cleanliness, varnish and sludge, oxidation control, and emission system and seal compatibility. These specifications are far more stringent than ILSAC GF-5 specification.

Duragard® Diamond Plate® dexos1 100% SYNTHETIC SAE 5W-30 is an API SN and ILSAC GF-5 Resource Conserving Performance Motor Oil and is approved and licensed by General Motors for worldwide warranty service for all GM gasoline engine cars and trucks where a SAE 5W-30 dexos1 is required. Duragard® dexos1 100% Synthetic SAE 5W-30 supersedes the GM 6094M and GM 4718M specifications for currant and older GM vehicles. Duragard® dexos1 is specifically designed for use in GM gasoline engines, but may be used wherever ILSAC GF-5 and API-SN 100% Synthetic SAE 5W-30 or previous specifications are called for.

Duragard® Diamond Plate® dexos1 100% SYNTHETIC SAE 5W-30 provides the highest level of engine protection available, even under the most severe operating conditions. Duragard® dexos1 5W-30 has exceptionally high viscosity that indices minimize cold weather thickening, which greatly reduces battery drain and engine wear, even at subzero startups and also provides exceptional resistance to high temperature oxidation thickening.


  • * Exceeds warranty requirements of engine manufacturers that require a type API SN or ILSAC GF-5 dexos1 100% Synthetic 5W-30 motor oil.
  • * Formulated to prevent engine wear. Even in the most severe GM tests Duragard® dexos1 exceeds the performance limits by 65%.
  • * Keeps pistons cleaner than GF-5 minimizing oil consumption and maintaining power and compression performance.
  • * Chemistry significantly outperforms the industry requirement, reducing engine sludge to near zero.
  • * Emission conserving protecting the car's catalyst system to help protect the environment.
  • * For use in all naturally aspirated or turbo-charged gasoline engines.

This product meets, or exceeds the requirements similar to the following manufacturers and global specifications:
