For the 2020 Honda Accord with the 1.5-liter turbo engine, the standard oil capacity is 4.5 quarts when changing the oil with the filter, about 4.1 quarts if the filter is not replaced. The recommended oil type is a synthetic 0W-20. This article breaks down the numbers and what to expect during an oil change.
The 1.5T engine uses 0W-20 synthetic oil as the default specification for most temperatures, and the capacity figures depend on whether the oil filter is replaced during the change. In practice, you’ll typically fill to 4.5 quarts after installing a new filter, then check the level with the dipstick and top off if needed.
