Diesel prices on the rise

Diesel prices have been on the rise for the past few weeks.

Kelvin Jackson, who works for Expert Maintenance Services, said the costs of diesel prices affect his company.

"Everything matters to the bottom line. Whenever there's an increase anywhere, especially with diesel because that's one of our primary expenses, we feel it pretty hard," said Jackson.

Texas A&M Chemical Engineering department head, Nazmul Karim, said fuel prices depend on the cost of crude oil.

"The crude oil price is increasing for a while, thus the gasoline and diesel will become more expensive in the short time. If the geopolitical situation changes, especially in the Middle-East, the price fluctuations will be more," said Karim.

Karim told KBTX there are no operational changes in the refineries that should bring on even higher prices. But there is a chance they could increase if another hurricane like Harvey comes through.

Jackson said another hurricane would be bad news for them because of how prices would rise.

"Of course we're apprehensive about it because as we mentioned it definitely affects it and it's beyond our control so anything that's beyond our control should be a cause of concern," said Jackson.

He said his company hopes to see a decline in the prices soon.

"We're praying and hoping yes that'll level out ,but as in all things it fluctuates so we've just got to roll with the punches," said Jackson.

While prices are high there are things you can do as a motorist to improve your fuel economy. Some of those are avoiding harsh acceleration and breaking. You can also keep less weight in your car.
