Is running a regular 86 on the T6 engine okay in the long run? Running premium drains my bank account pretty quickly. And my mother is on my arse about saying I can put regular in the car to save money. But I feel like I need to fact-check this as the owner's manual says it's 91 required. I don't trust that it can be good for the engine to put normal in it as it is a high-performance engine. but I need other opinions.
Any help is much appreciated.
