Shell Oil 9404106021 Rotella ELC Extended Life Coolant Antifreeze Concentrate 1 Gallon

Shell Rotella ELC Extended Life Coolant/Anti-Freeze is a "fill for life" ethylene glycol-based concentrate engineered for heavy-duty diesel, gasoline, and natural gas powered engines — both on-road and off-road. Its advanced nitrited carboxylate inhibitor chemistry delivers outstanding cooling system protection with dramatically reduced maintenance requirements.

Key Features:

• Extended service life — minimum 600,000 miles with only one ELC Extender addition at 300,000 miles
• Unique inhibitor system — extended life carboxylate technology with nitrite and molybdate as secondary inhibitors
• No SCAs required — contains no silicate, borate, nitrate, or phosphate; no traditional Supplemental Coolant Additive (SCA) additions needed
• Superior heat transfer — approximately 8% better heat transfer than conventional silicate-containing heavy-duty coolants
• Excellent corrosion protection — protects all cooling system metals including aluminum, brass, cast iron, steel, solder, and copper
• Improved water pump seal life — low dissolved solid levels reduce wear and scale deposits
• Wet sleeve cylinder liner protection — excellent pitting protection for liner longevity
• Freeze and boil-over protection — effective heat transfer guards against both extremes

Industry Certifications & Standards:

• ASTM D3306 and D6210
• Caterpillar EC-1
• TMC RP 329 and TMC RP 338

Shell Rotella ELC Concentrate has been proven across more than 150 million kilometers of fleet testing. This concentrate formula is ideal wherever a silicate-free and phosphate-free heavy-duty coolant is required. Sold as a case of 6 one-gallon jugs. Note: dilution or mixing with non-equivalent coolants will reduce or eliminate extended life properties.
