These lubricants are intended for the lubrication of transmissions, transfer cases, differentials and planetary gear sets found in trucks and construction equipment. They use a synthetic base for excellent stability, long life, extreme temperature operation, improved fuel economy, reduced wear and cleaner components.
SYN HDH and SYN IDO are suitable alternatives for use where an Eaton Roadranger™ product is recommended. Mack Trucks Inc approves SYN HDH for use under its GO-J and GO-J Plus programs, and also approves SYN IDO under its TO-A Plus program. The US Military also approves the use of SYN HDH under its Mil-PRF-2105E program.
Irving SYN HDH has a complete protection package for the extreme pressure (EP) conditions of differentials, including limited slip, and planetaries working under the heaviest load conditions. It meets the performance requirements of API* GL-5, Rockwell Corporation and Dana Corporation.
Irving SYN HDH is available in 2 multi-grades to cover the broadest possible temperature ranges. The use of synthetic base rather than mineral oil reduces friction in extreme conditions, increasing fuel economy by making more horsepower available to the driving wheels.
SYN IDO is specially formulated for manual transmissions in class 6, 7 and 8 trucks where straight mineral oils (non-EP) or SAE 50 diesel engine oil is usually recommended. Irving SYN IDO has wider operating temperature range than the alternatives. At low temperatures, this gives easier shifting with less drag and gear wear, and lubricating vital transmission parts quickly. At high temperatures, this oil provides a thicker protective oil film than mineral oil lubricants, reducing friction and wear. Taken together, these advantages mean better fuel economy and transmission life.
NOTE: SYN IDO IS NOT APPROVED FOR USE AS ENGINE OIL.
When switching from mineral to synthetic lubricants, the two may not be compatible so it is important to drain the unit completely before refilling with the synthetic lubricant. After the change, all seal areas should be checked for the first 20,000 Km.
