The remark about the donuts and chicken tenders is almost certainly a reference to a diesel car using Waste Vegetable Oil (WVO) as fuel - also known as a greasecar and other names. If you're not familiar with the process, I very highly recommend checking it out - doing the simple and inexpensive conversion to use veggie oil fuel can easily mean that you never need to pay for gas again - in fact, many businesses will PAY YOU to take their used veggie oil away.
