Sidewinder fuel is great. I’ve been running sidewinder 30% for years now coming from VP. I Race1/8 Nitro buggy and Truggy. Engines run cooler than they did with VP and produce much better smoke. I would definitely recommend sidewinder ,dozens of people at my local track run it and have had no issues most guys getting 7 to 10 gallons on their engines before any maintenance needed on their engines.
