A positive displacement, rotary type, volumetric flow meter reads low with an error reading of 1% when used to measure flow of heavy oil and 2.5% when used to measure the flow of diesel oil.

What is the most likely cause of this difference in error?

The meter internal parts are worn and need replacement.
