Are there any oil companies that produce non bio diesel?

Yes, there are several oil companies that produce non-biodiesel fuels, primarily focusing on conventional petroleum products such as gasoline and diesel derived from crude oil. Major oil companies like ExxonMobil, Chevron, and BP primarily produce fossil fuels, including regular diesel, which is not derived from biological sources. Additionally, some companies are exploring synthetic fuels and renewable diesel, which, while produced from renewable resources, are distinct from traditional biodiesel.
