Synthetic Transmission Oil
Synthetic lubes and oils maintain their viscosity at low and high temperatures and have less friction and heat, which promotes energy efficiency and fuel economy. Significant improvements have been made on synthetic lubricants and increased scale is contributing to lower costs.
NACFE is considering a report on synthetic engine oil and other lubricants and additives.
Benefits
Fuel Savings
Less friction and heat promote fuel economy.
Stability at Higher Temperatures
Synthetic oil tends to have a higher viscosity index so it remains thick at high temperatures.
Longer Maintenance Intervals
Because of the improved oxidation and thermal stability of synthetic lubes, they are less likely to thicken as they age allowing for extended drain intervals.
Better Protection and Less Wear
The higher viscosity of synthetic transmission oil leads to less component wear.
Challenges
Initial Cost
Synthetic transmission lubes come with a higher initial purchase price but that can be offset by some of its benefits.
Availability on the Road
It may be more difficult to find these lubes when the truck is out on the road away from its normal supplier.
