What grade of gas does your large gas engine require
With the big V-8 and V-10 engines do you have to burn a higher octane than regular unleaded? Back in the days of muscle cars you had to burn premium. Does that apply to big blocks in RVs?

The compression ratio is only about 9:1 so you can use regular gas. They have found better ways to make power then raising the compression ratio.
