There are two main reasons why vehicle manufacturers recommend thinner or lighter viscosity grades of motor oil. First, a gain in fuel economy can be achieved with lower viscosity oil. Second, thinner motor oil is essential for easy starting, and for proper lubrication once the engine starts.

Thinner oils, such as SAE 0W-20, 5W-30, will flow faster than heavier motor oils during start-up and initial engine operation and will help protect the engine from excessive wear. Multigrade oils will also offer the same high-temperature protection as single grade motor oils. Always check your vehicle owner’s manual to select the proper viscosity grade based on the expected temperature range.

Using Ultra Tec 0W-20, 5W-30, 10W-30 or Ultra Premium 10W-30 with Fuel Saving Technology allows for significant savings in fuel while still providing proper lubrication once the engine starts.
