Investment guru Jim Cramer says he is disgusted with fossil-fuel shares and is done with oil stocks.

Cramer spoke after weaker crude oil and gas prices drove quarterly results sharply lower at Exxon Mobil Corp. and Chevron Corp., pushing down shares at the two largest U.S. oil producers and signaling a weak start to the new year, Reuters explained.

The CNBC host said oil and other fossil fuel stocks are now like tobacco stocks.

“This has to do with new kinds of money managers who frankly just want to appease younger people,” Cramer said on CNBC. “We’re starting to see divestment all over the world,” he said.

“I’m done with fossil fuels ... they’re just done. We’re starting to see divestment all over the world,” Cramer said. “You’re seeing divestiture by a lot of different funds. It’s going to be a parade. It’s going to be a parade that says, ’Look, these are tobacco and we’re not going to own them,’” he said.

While one-time asset sales or write downs were large factors, the two companies said earnings suffered from weaker margins in crude oil, natural gas, chemicals and fuel production. They gave tepid outlooks for the near term.

"There's no silver bullet on improving returns in a flat commodity price environment," said Chevron Chief Executive Mike Wirth. "You roll up your sleeves and you get to work on all the little things."

Shares of Exxon (XOM) and Chevron (CVX) were both at least 3.5% lower in trade on Friday, pressured by the results and worries about slowing global economic growth.
