Is Cerma Treatment Worth It?
Real Customer Results & Testing Data
EPA ETV protocol testing. 12+ years of verified buyer reviews. The mechanism that separates permanent ceramic from every other additive on the shelf. Here is the complete evidence.
⚡ Short Answer
Cerma STM-3 works because it operates on a categorically different mechanism than standard oil additives. Nano Silicon Carbide (Mohs 9.5) bonds permanently to metal surfaces inside your engine — it does not dissolve in oil and drain at the next service interval. Performance has been independently tested under EPA ETV protocol. Verified buyers with vehicles ranging from 30,000 to 280,000 miles consistently report reduced engine noise, lower oil consumption, smoother cold starts, and improved throttle response. The permanent nature of the treatment means the benefit is cumulative — not a temporary improvement that resets at every oil change.
🔬 What the Testing Data Shows
Most engine additive claims are based entirely on manufacturer-conducted tests — controlled in-house, with results reported by the company selling the product. Cerma STM-3 technology has a different evidentiary foundation: independent testing conducted under the EPA's Environmental Technology Verification (ETV) program.
The ETV program, administered through the U.S. Environmental Protection Agency, evaluates environmental and automotive technologies under rigorous, third-party-controlled protocols. Testing is conducted by independent laboratories using standardized methodologies — not by the manufacturer. The results are what they are, regardless of what the manufacturer hoped they would show.

The significance of EPA ETV verification is what it is not: it is not a manufacturer brochure claim, not a sponsored test, not a cherry-picked result from a single controlled demonstration. It is independent protocol testing — the same standard applied to any environmental technology submitted for verification. Cerma's STM-3 Nano SiC technology passed.
Why this matters in a category full of noise: The engine additive market contains hundreds of products. Nearly all of them make friction reduction claims. Almost none have independent third-party verification at the rigor level of EPA ETV protocol. This is one of the most meaningful technical differentiators Cerma holds over competitor products.
❌ Why Most Engine Additives Disappoint
If you have tried an engine additive before and noticed no lasting improvement — or an improvement that vanished by the next oil change — the reason is almost certainly this: the additive was dissolved in the oil. When the oil drained, so did every benefit.
This is not a knock on the chemistry involved. PTFE (polytetrafluoroethylene), Molybdenum Disulfide (MoS₂), and various chemical friction modifiers are all legitimate lubricants. They genuinely reduce friction while present in the oil film. The problem is structural, not chemical:
- PTFE-based additives (Mohs ~2.0): Softer than a fingernail. Provide temporary lubricity suspended in oil. Drain completely at every service interval. Cannot harden worn metal surfaces.
- MoS₂ additives (Mohs ~1.0–1.5): Excellent boundary lubricant while suspended in fresh oil. Zero cumulative benefit — each oil change resets to zero.
- Chemical friction modifiers: Effective while fresh, depleted by the end of the oil change interval, drained completely at service.
- High-mileage oil formulas: Seal conditioners and viscosity modifiers that address the fluid — not the worn metal surfaces causing symptoms.
🔑 The Structural Problem with Oil-Based Treatments
If you spent $20 on an additive at every oil change for 5 years (20 oil changes), you spent $400 — and received zero cumulative benefit. Each treatment was the first treatment. The worn metal surfaces in your engine are exactly as worn after 20 temporary treatments as they were after 0. The only way to permanently improve a surface is to permanently change the surface.
⚙️ The Mechanism That Makes Cerma Different
Cerma STM-3's active ingredient is 100% Nano Silicon Carbide — no petroleum carriers, no PTFE, no oil-dissolved chemistry. SiC is a ceramic compound with properties that make permanent metal bonding possible:
- Mohs hardness 9.5 — second only to diamond. Harder than any engine metal: hardened steel (Mohs 7.5), cast iron (5.5), aluminum (4.0).
- Melting point 2,730°C — no engine operating condition, even under extreme load, approaches this temperature at metal surfaces.
- Particle size ~10 nanometers — small enough to penetrate the micro-surface irregularities of engine metal and bond within the sub-surface structure.
The bonding process unfolds over 3,000–5,000 miles of normal driving after treatment:
What "permanent" actually means: Cerma STM-3 is not a long-lasting additive — it is a one-time surface modification. The SiC that bonded to your cylinder walls during the first 5,000 miles after treatment is still bonded at 50,000 miles later. It has not depleted, degraded, or drained. The ceramic matrix has Mohs 9.5 hardness and a 2,730°C melting point — there is no engine operating condition that degrades it.

I've been skeptical of additives my whole life. A friend talked me into trying Cerma on my Ram 1500 at 118,000 miles. I added it at my oil change and honestly forgot about it. About 2,000 miles later my wife asked me if I did something to the truck — said it sounded different. Quieter. I hadn't told her I added anything. That was enough for me.
My 6.7 Cummins had that cold-start valve train noise every morning. Not terrible, but it was there every single time for two years. Three months after Cerma, it's gone. I was checking my dipstick every week expecting the oil to look different — it doesn't look different, but the engine sounds different. The noise is gone.
236,000 miles on my 4Runner. Was adding a quart every 1,500 miles between changes. Added Cerma to fresh synthetic, drove the next interval and checked — barely needed to top off at all. Added maybe a quarter quart at 4,000 miles. That alone is worth the price. The engine also idles noticeably smoother at stop lights.
Fleet manager, 14 vehicles. We've been running Cerma in our vans for three years now. The maintenance cost difference is real. Fewer oil consumption complaints from drivers, two engines that were showing wear symptoms smoothed out significantly. We won't go back to running without it.
I read everything I could find before buying — technical forums, skeptic boards, everything. The EPA ETV verification is what pushed me to try it. That's not a marketing document; that's independent protocol testing. Bought it, added it to my Tacoma at 155,000 miles. Six months later the truck has noticeably better throttle response and the idle is cleaner. The science checks out and the results confirmed it.

🤔 Addressing the Skeptics: Answering the Hard Questions
If you are doing real research before spending $105.60 on an engine treatment, you should be skeptical. The engine additive category has a long history of overblown claims. These are the most common objections — answered honestly.
💰 The Real Cost Comparison
The $105.60 price of Cerma STM-3 gas engine treatment is only expensive if you compare it to the price of a single competing additive bottle. Compared over actual vehicle ownership — which is the only comparison that matters — it is almost always the lower total cost option.
5-Year Total Treatment Cost (20 oil change cycles)
* Based on 5 years / 20 oil change cycles. Cost reflects additive/treatment only — not oil itself. Oil-dissolved additive costs reset to $0 cumulative benefit at each oil change.
The more meaningful cost comparison is the cost of what Cerma prevents. A single engine replacement on a modern vehicle runs $4,000–$12,000+ depending on the engine and labor. A rebuilt transmission: $2,500–$5,000. An extended engine life that defers these costs by even 50,000–100,000 miles converts a $105.60 investment into a substantial financial return — in addition to the daily performance improvements drivers report from mile 1,000 onward.
