definitely helps
In my experience one of those small bottles added to a tank bumps the octane by approx 2 points. With 90 octane my 5.9 Durango would detonate like mad but no issues with 92, or one bottle added. I always carried a few of those bottles when going to remote areas where only 90 octane was available
