They have treat rates that are not the same which leads me to believe that this product is likely 25-30%PEA. While the 12 oz product is ~15% PEA. **Q: The pea is 10% to 24% for gumout. redline is 28% to 32% the only other that has pea is chevron techron all good but redline is best agree?** A: Per the Gumout MSDS Polyetheramine: 10 - 30% I've come to understand that this covers all products, this one and there is a larger 12 oz product. They have treat rates that are not the same which leads me to believe that this product is likely 25-30%PEA. While the 12 oz product is ~15% PEA. I can't seem to pull up a recent MSDS for Redline, but prior versions say 25-30% or <30%. So, bottom line is they are comparable on a cost per PEA basis. **Q: Will it affect smog test if i use it couple days before?** A: If you want to be safe, run all that fuel out before the test. That way you will get all the cleaning benefit. Honestly, I do not think the chemicals will change the test if that was your question. The Cat converter will burn most everything. **Q: i use octane buster in my 93 vet. can i use this with it?** A: Absolutely! ## Customer Reviews ### ⭐⭐⭐⭐⭐ No Complaints *by S***7 on July 31, 2026* We have older cars with higher mileage and this stuff seems to do its job, we've had no issues and no complaints.
