Frequently Asked Questions
What temperature range is TO-4 SAE 10W suitable for?
TO-4 SAE 10W is designed for cold-weather operation, typically suitable for ambient temperatures as low as -30 degrees C. It provides reliable flow and lubrication during cold starts in arctic and sub-zero conditions.
Can I use TO-4 10W year-round?
TO-4 10W is primarily a cold-weather grade. In warm climates or high-load applications, a heavier grade (SAE 30 or SAE 50) is typically required to maintain adequate film strength. Follow the equipment temperature/viscosity chart.
Is TO-4 10W suitable for hydraulic systems?
Yes, TO-4 10W can be used in hydraulic systems that share fluid with the transmission, particularly in cold environments where thicker grades would cause sluggish hydraulic response. Check the equipment specifications.
