ComStars Super Heat has been a trusted solution for over 45 years, offering comprehensive care with 8 treatments in 1. It supports smooth operation by melting ice, lowering the pour point, managing waxing and jelling, reducing water, dissolving sludge, cleaning parts, minimizing soot, and helping protect against rust.Fuel treatments are essential for maintaining fuel system performance. Over time, impurities like carbon and water can accumulate, affecting efficiency. Regular use of Super Heat helps reduce these issues and supports consistent operation.In colder climates, fuel can thicken, potentially impacting flow. Super Heat helps maintain optimal performance in low temperatures, ensuring fuel systems operate effectively throughout the year. Add 8 oz. with each 275-gallon refill to keep systems running smoothly.
After using Comstar Super Heat, I can definitely say it lowered the pour point of my oil. My generator runs smoother, and I haven’t had ice issues since. I’ll keep it stocked for sure!

Great for preventing sludge buildup
I’ve been using this Comstar Super Heat for a few months, and it’s been fantastic at dissolving sludge in my fuel tank. Plus, I love that it controls waxing. Definitely recommend if you want peace of mind in winter!

Good product, but slow shipping
I’ve used the Comstar Super Heat several times, and it does help with my heating oil. It controls waxing nicely, but the shipping took longer than I expected. Just plan ahead if you need it fast!

Not worth the hype
Honestly, I didn't see much difference with the Comstar fuel treatment. It might work for some, but my oil is still jelling in the cold. Maybe I got a bad batch?

A solid option for my fuel treatment needs
This 8-in-1 fuel treatment from Comstar is doing the job well. The pour point reduction really works, but I kinda wish the packaging was better. It came a bit dented. Still, it’s been effective overall!
