Review on 16.9 Oz Rislone Nano Prime Synthetic Engine Oil Additive by Cody Mckechnie
Improves engine - my new review
Noticed an immediate difference. I take very good care of my car, best oil, change often, always doing preventive maintenance. This stuff made my engine, which already ran great, run even better. I'll add it every 6 months or so
Pros
- Got 1 to 2 miles per Gallon better. Pluss stopped slight knock when cold.
Cons
- Did nothing but possibly harm my engine more.
