Sales from other oils and related products were $1.0 billion and $1.3 billion for the nine months ended September 30, 2020 and 2019, respectively, decreasing $273.5 million, or 20%, due to a decrease in prices, partially offset by an increase in volume sold. Our product margin from other oils and related products was $58.8 million and $40.6 million for the nine months ended September 30, 2020 and 2019, respectively, an increase of $18.2 million, or 45%, primarily due to more favorable market conditions in distillates, largely in the second quarter. During the second quarter of 2020, there was a significant recovery in the supply/demand imbalance at the end of the first quarter. The forward product pricing curve flattened which positively impacted our product margins. 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 margins for the first three months of 2020.
Results for Gasoline Distribution and Station Operations Segment
Gasoline Distribution. Sales from gasoline distribution were $0.7 billion and $1.0 billion for the three months ended September 30, 2020 and 2019, respectively, a decrease of $0.3 billion, or 31%, due to decreases in prices and volume sold largely due to the impact of the COVID-19 pandemic. Our product margin from gasoline distribution was $101.4 million and $107.6 million for the three months ended September 30, 2020 and 2019, respectively, a decrease of $6.2 million, or 6%. While in the third quarter of 2020 our fuel margins (cents per gallon) were higher than the same period in 2019, in the third quarter of 2019 wholesale gasoline prices declined which favorably impacted our fuel margins (cents per gallon).
Sales from gasoline distribution were $1.9 billion and $2.9 billion for the nine months ended September 30, 2020 and 2019, respectively, a decrease of $1.0 billion, or 34%, due to decreases in prices and volume sold largely due to the impact of the COVID-19 pandemic. Our product margin from gasoline distribution was $305.4 million and $282.9 million for the nine months ended September 30, 2020 and 2019, respectively, an increase of $22.5 million, or 8%, due to higher fuel margins (cents per gallon) which more than offset the decline in volume sold. Our product margin for the first nine months of 2020 benefitted from declining wholesale prices in the first quarter of 2020, primarily in March due to the COVID-19 pandemic and geopolitical events and to higher fuel margins (cents per gallon) in both the second and third quarters compared to the same periods in 2019. 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 $122.8 million and $128.9 million for the three months ended September 30, 2020 and 2019, respectively, a decrease of $6.1 million, or 5%. Our product margin from station operations was $57.5 million and $61.1 million for the three months ended September 30, 2020 and 2019, respectively, a decrease of $3.6 million, or 6%. The decreases in sales and product margin are primarily due to less activity at our convenience stores, primarily due to the impact of the COVID-19 pandemic.
