I'm sorry, but this is just a ridiculous comment and terrible advice. I was driving a borrowed Mercedes over Christmas purchased earlier that year. When I filled it with gas it clearly said, "minimum octane rating 91." Sure, you can use regular gas and on any modern car it shouldn't cause damage, but it's silly to pay that much for a car and cheap out $.20-$.30 per gallon when it is designed and recommended for it.
I included the cost of regular gas because even that showed the article was being disingenuous about cost even using those numbers.
Per a 2017 jalopnik article[1], any short term gains by using cheaper gas are likely to be lost because of decreased performance. While any short-term problems will likely be addressed by anti-knock sensors, long term problems aren't known. If you're that price-sensitive, buy a car designed for regular octane fuel.
