Engine manufacturers recommend a 10% limit on mixing coolant types.Ģ Heavy Duty conventional coolants are antifreeze products treated with some or all of the following inorganic corrosion inhibitors: n Hybrid coolants are composed of organic acid technology combined with strong inorganic buffer agents like borate or phosphate. 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.1 Ethylene Glycol (EG) Coolants Color Inhibitor Package Meets Specifications North American Market Light Duty Heavy Duty Notes OEM Other Conventional Conventional Conventional Hybrid OAT OAT High Silicate* Low Silicate Fully Formulated (HOAT) (2-ethyl- (other w/out w/out w/out Full Daimler TMC ASTM w/out SCA with SCA hexanoic acid) organic acid) Silicate Phosphate Borate OAT Chrysler Ford GM CAT Cummins DDC RP329 D6210 Passenger Car High Silicate Green <2003 <2003 <1995 Arctic Blend Universal Green <2003 <2003 <1995 Fleetguard Universal Low Silicate Green <2003 <2003 <1995 Fleetguard Universal Recycled Coolant Green <2003 <2003 <1995 Shell Shellzone Low Silicate Green <2003 <2003 <1995 Universal Low Silicate Green <2003 <2003 <1995 Arctic Blend HD Fully Formulated Pink CAT Diesel Engine Antifreeze Coolant Pink Detroit Diesel PowerCool Pink Fleetguard ES Compleat Fleetguard Fleetcool Fleetguard Fleetcool Recycled Coolant Old World Industries Fleet Charge Prestone Heavy Duty Arctic Blend G-Plus DaimlerChrysler / Mopar 2003 Fleetguard Fleetcool E Ford Motorcraft Premium Gold Peak CF-EL Extended Life Coolant Valvoline Zerex G-05 CAT ELC ChevronTexaco Delo Extended Life Coolant GM DE-COOL Prestone Extended Life 5/150 Shell Rotella Extended Life Coolant Texaco Havoline DE-COOL Texaco Havoline Extended Life Coolant Valvoline Zerex ExtremeLife 5/150 Valvoline Zerex Extended Life Extreme 3/300 Detroit Diesel PowerCool Plus Old World Industries Final Charge Fleetguard ES Optimax Compatibility*** Conventional High Silicate Conventional Low Silicate w/out SCA Blue Pink Green Pink Pink Yellow Orange Pink Yellow Yellow Yellow Red ** Red ** Orange Orange Red ** Orange Red ** ** Orange Red Red Red Red Conventional Fully Formulated with SCA Hybrid (HOAT) OAT (2-ethyl-hexanoic acid) OAT (other organic acid) Comments *Do not use SCA with conventional high silicate antifreezes **Requires special silicate additive liquid or silicate filter to protect certain gasket materials ***Mixing different types of antifreezes can reduce their corrosion protection. Over-dilution will require initiating SCA use or draining and refilling the cooling system with Shell Rotella ELC. Please note that dilution of Shell Rotella ELC by more than 15% with non-equivalent coolants or water is not recommended. See index for freeze point adjustment chart. If coolant is red, has no deposits and has a freeze point of between –15✯ and –60✯ then the coolant is considered in suitable condition for further use. At every PM, or at least twice per year, check the color and freeze point of your coolant. Top up only with Shell Rotella ELC Pre-diluted 50/50 or an equivalent brand of ELC like Fleetrite ® ELC. To use this product just follow your OEM’s instructions on how to drain, flush and refill your cooling system. Maintenance is simple with ROTELLA ELC 50/50. Tests with ROTELLA ELC show that heat transfer is about 8% better with RELC than with conventional heavy duty, silicate- containing coolants. 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. After 600,000 miles or 12,000 hours it is recommended that the coolant be tested for continued use. 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. 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.
