Manufacturer wording: Valvoline PI sheet: "an approved formula for the following specifications: Chrysler MS 9769, Cummins CES 14603, Ford North America WSS-M 97B51-A1, GE Wind Turbines, JCB STD00088, John Deere JDM H24, Mercedes-Benz before 2017, MTU MTL 5048, MAN List 3.3.7, MTU/DDC" and "formulated to meet or exceed" ASTM D3306, ASTM D6210, GM 1825M, GM 1899M, CAT EC-1, Detroit Diesel 7SE298 and

"Meets X per manufacturer" is our shorthand for any of the manufacturer's own phrases: meets, meets or exceeds, approved, or recommended for applications requiring. It is the manufacturer's claim, not an approval by Coolant.com or by the vehicle maker. Codes are copied as published. Some sources list codes for compatibility rather than formal approval. The wording above shows which.

What the manufacturer says it is for

suitable for passenger cars, light trucks and heavy-duty vehicles.

Quoted from the manufacturer's page. Coolant.com has not verified fitment for any vehicle, and a listed make or year range is the manufacturer's statement, not ours.

Compatibility notes

  • If your owner's manual calls for MS-9769, Zerex lists that code for this product. Read the exact wording above, and confirm against your manual.
  • Chemistry is listed as HOAT. Mixing different chemistries can shorten coolant life. See OAT vs HOAT vs IAT and use the mixing checker before topping up.
  • Sold as a concentrate: dilute with distilled or deionised water as the label directs. See premix vs concentrate and the freeze and boil calculator.

Note: Valvoline PI sheet (2021) hosted by a distributor (ProSource Diesel). Chemistry: Valvoline describes G05 as "lower-silicate, reduced pH, phosphate free" and nitrite-containing; HOAT is the term Valvoline uses for G-05 on valvolineglobal.com. Service life on Valvoline's Latin America page: 5 years / 240,000 km light duty.

Always check your owner's manual first. Use the coolant spec printed in your owner's manual or service information. A listing here is the manufacturer's own claim (meets, exceeds, approved or recommended, worded as they put it). It is not our approval and not a fitment guarantee for your vehicle. If in doubt, ask your dealer or a qualified mechanic.
