Thanks, Jeff, and good morning, everyone. For the fiscal 2020 third quarter, our home heating oil and propane volume increased by 14 million gallons or 39% to 51 million gallons, as the impact of colder temperatures and the additional volume provided from acquisitions more than offset net customer attrition and other factors.
Temperatures for the quarter were 46% colder than last year and 18% colder than normal. The volume of other petroleum products sold decreased by 8 million gallons or 19% to 34 million gallons, as additional volume provided by acquisitions of 2 million gallons was more than offset by a decline in motor fuel sales, largely due to COVID-19.
Our product gross profit increased by $16 million or 29%, due to the higher home heating oil and propane volumes sold. Delivery and branch decreased by $10 million as the additional costs from acquisitions of $2 million were more than offset by a $12 million or 14% decrease in expenses within the base business.
The cost decline in the base business was attributable to $2 million of lower bad debt and credit card processing fees, lower insurance expense of approximately $5 million, lower medical costs of $2 million and other reductions in operating expenses totaling $3 million or 3.5%, as we continue to improve Star's operating efficiency.
General and administrative expenses did rise by $1.5 million due to an increase in profit sharing expense. Our net loss decreased by $23 million due to an increase in adjusted EBITDA of $26 million and a noncash favorable change in the fair value of derivative instruments of $5 million, partially offset by a decrease in our income tax benefit.
Adjusted EBITDA increased by $26 million to $6 million and was positive. Acquisitions provided $1 million of adjusted EBITDA, while adjusted EBITDA in the base business increased by $25 million due to the impact of, one, the impact of higher home heating oil and propane volumes sold; two, lower operating expenses in the base business of $10 million; and lastly, an improvement in our net service and installation profitability of $1 million. For the first 9 months of fiscal 2020, our home heating oil and propane volume decreased by 29 million gallons or 9% to 295 million gallons, as the additional volume provided by acquisitions was more than offset by warmer temperatures, net customer attrition and other factors.
Temperatures for the first 9 months of fiscal 2020 were 6% warmer than last year and 10% warmer than normal. The volume of other petroleum products sold did decrease by 11 million gallons or 9%, as the additional volume provided by acquisitions of 9 million gallons was more than offset by lower wholesale demand due to the warmer temperatures and a decline in motor fuel sales, again due in part to the impact of COVID-19.
Our product gross profit decreased by $17 million or 4% as the decline in home heating oil and propane volumes more than offset an increase in per gallon margins. Delivery and branch expense declined by $41 million as the additional costs from acquisitions of $9 million was more than offset by a $51 million or 17% decrease in expenses within the base business.
The decline in the base business was attributable to a $10 million or 11% reduction in direct delivery costs due to the lower volumes, a $4 million decrease in our concierge program, which we've greatly reduced, $4 million of lower bad debt and credit card processing fees, lower insurance expense and insurance claims of $6 million, lower medical costs of $3 million and other reductions in operating costs totaling $11 million or 3.6%.
Operating expenses were also reduced by $12 million due to the impact of our weather hedging program. In fiscal 2019, [ we ] recorded a charge of $2 million versus a benefit of $10 million in fiscal 2020, reflecting this year's warmer winter temperatures during the hedge period.
General and administrative expenses decreased by $4 million, primarily due to lower legal and professional expenses of $4 million. Net income increased $35 million or 67% to $86 million, due to a $33 million increase in adjusted EBITDA and a noncash favorable change in the fair value of derivative instruments of $17 million, partially offset by a $14 million increase in income tax expense. Year-to-date adjusted EBITDA increased by $33 million to $158 million. Acquisitions provided $9 million of adjusted EBITDA, while adjusted EBITDA in the base business increased by $24 million.
In the base business, the impact of lower home heating oil and propane volumes sold was more than offset by higher per-gallon home heating oil and propane margins, lower operating expenses in the base business of $55 million, a favorable change in the amount due under the company's weather hedging program of $12 million, and an improvement in net service and installation profitability of $4 million.
With regard to our weather hedge program, warmer temperatures during fiscal 2020 during the winter weather hedge period resulted in us collecting $10 million. By contrast, the third quarter of fiscal 2020 was colder than normal and resulted in us selling more volume than anticipated.
If the additional degree days in the third quarter had occurred in the period covered by the weather hedge, which is from November through March, the payout under our weather hedge program would have been less than $2 million. And with that, I would like to turn the call back over to Jeff.
