Results for Wholesale Segment
Gasoline and Gasoline Blendstocks. Sales from wholesale gasoline and gasoline blendstocks were $819.4 million and $971.1 million for the three months ended March 31, 2021 and 2020, respectively, a decrease of $151.7 million, or 16%, due to a decrease in volume sold. Our gasoline and gasoline blendstocks product margin was $16.4 million and $9.5 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $6.9 million, or 72%, primarily due to more favorable market conditions in gasoline. In contrast, in the first quarter of 2020, the COVID-19 pandemic and the price war between Saudi Arabia and Russia caused a rapid decline in prices, steepening the forward product pricing curve which negatively impacted our product margin in gasoline for the first three months of 2020.
Crude Oil. Crude oil sales and logistics revenues were $16.9 million and $6.5 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $10.4 million, or 162%, due to increases in prices and volume sold. Our crude oil product margin was ($4.5 million) and ($4.4 million) for the three months ended March 31, 2021 and 2020, respectively, a decrease of $0.1 million, or 1%.
Other Oils and Related Products. Sales from other oils and related products (primarily distillates and residual oil) were $715.2 million and $630.7 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $84.5 million, or 13%, due to increases in prices and volume sold. Our product margin from other oils and related products was $18.6 million and $0.4 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $18.2 million, primarily due to more favorable market conditions and weather that was 16% colder than the first quarter of 2020. In contrast, in the first quarter of 2020, the COVID-19 pandemic and geopolitical events caused a rapid decline in prices, steepening the forward product pricing curve, which negatively impacted our product margins for the first three months of 2020. In addition, our product margin in other oils and related products was negatively impacted due to significantly warmer weather during the first quarter of 2020 when temperatures were 19% warmer than normal.
Results for Gasoline Distribution and Station Operations Segment
Gasoline Distribution. Sales from gasoline distribution were $756.0 million and $745.6 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $10.4 million, or 1%, due to an increase in prices partially offset by a decline in volume sold. Our product margin from gasoline distribution was $80.2 million and $107.2 million for the three months ended March 31, 2021 and 2020, respectively, a decrease of $27.0 million, or 25%, primarily due to lower fuel margins (cents per gallon) and, to a lesser extent, a decline in volume sold. Wholesale gasoline prices rose during most of the first quarter of 2021. Rising wholesale gasoline prices typically compress our gasoline product margin, the extent of which depends on the magnitude and duration of that rise. In the first quarter of 2020, our product margin benefitted from higher fuel margins (cents per gallon). Wholesale gasoline prices declined, primarily in March of 2020, due to the COVID-19 pandemic and geopolitical events. Declining wholesale gasoline prices can improve our gasoline product margin, the extent of which depends on the magnitude and duration of the decline.
Station Operations. Our station operations, which include (i) convenience stores sales at our directly operated stores, (ii) rental income from gasoline stations leased to dealers or from commissioned agents and from cobranding arrangements and (iii) sale of sundries, such as car wash sales and lottery and ATM commissions, collectively generated revenues of $100.2 million and $98.6 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $1.6 million, or 2%. Our product margin from station operations was $50.2 million and $48.6 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $1.5 million, or 3%. The increases in sales and product margin are due to increases in sundries and rental income.
Results for Commercial Segment
Our commercial sales were $145.7 million and $142.6 million for the three months ended March 31, 2021 and 2020, respectively, an increase of $3.1 million or 2%. Our commercial product margin was $4.2 million and $5.3 million for the three months ended March 31, 2021 and 2020, respectively, a decrease of $1.1 million, or 21%, primarily due to a decrease in bunkering activity.
