Shell Rotella ELC Extended Life Coolant/Anti-Freeze 50/50 has been proven, with over 100 million miles of fleet testing, to provide complete protection of all cooling system components.
The inhibitors in ROTELLA ELC 50/50, due to their special chemistry, are designed to go 600,000 miles on-road or 12,000 hours off-road with only one Shell Rotella ELC Extender addition at 300,000 miles or 6,000 hours. After 600,000 miles or 12,000 hours it is recommended that the coolant be tested for continued use. Shell Rotella ELC’s patented inhibitors, while providing complete cooling system component protection, also help reduce water pump failures, hard water scale deposits, silicate “green goo” and improve heat transfer. Tests with ROTELLA ELC show that heat transfer is about 8% better with RELC than with conventional heavy duty, silicate- containing coolants.
Maintenance is simple with ROTELLA ELC 50/50. To use this product just follow your OEM’s instructions on how to drain, flush and refill your cooling system. Top up only with Shell Rotella ELC Pre-diluted 50/50 or an equivalent brand of ELC like Fleetrite ® ELC. At every PM, or at least twice per year, check the color and freeze point of your coolant. If coolant is red, has no deposits and has a freeze point of between –15ºF and –60ºF then the coolant is considered in suitable condition for further use. See index for freeze point adjustment chart. Please note that dilution of Shell Rotella ELC by more than 15% with non-equivalent coolants or water is not recommended. Over-dilution will require initiating SCA use or draining and refilling the cooling system with Shell Rotella ELC. If contamination with non-equivalent /non-extended life coolants is suspected, it is recommended the ELC Contamination Test Strip Kit be used to confirm satisfactory carboxylate inhibitor content.
