Proven engine & fuel treatments
Products that pay for themselves.
AW10 & FTC Decarbonizer — our most "mind-blowing" performers
Skip the search. Tell us the symptoms and we'll point you at the treatment that sorts it.
Carbon built up where it shouldn't be. Clean it out from the inside.
FTC Decarbonizer →Dirty injectors and hard combustion quietly drink your fuel.
Cleanpower / CRD Fuel Enhancer →Metal-on-metal friction — where engine & component life quietly disappear.
AW10 Antiwear →Old oil residue robs power. Flush it before your next oil change.
Flushing Oil Concentrate →Start here. These are the treatments that turned us from customers into a company.
Engine feeling weak and expensive to run? That's carbon making your engine work harder than it has to.
Dose: 20 mL per 30 L of fuel — full dose rates on the product page and label.
Notchy gears, noisy diffs, hot-running engines? That's friction — and it's costing you fuel and engine life.
Dose: 20 mL per 1L of oil — add to existing oil, full rates on the product page and label.
These reviews come from customers of Cost Effective Maintenance Australia — our parent company, with 30+ years behind the products. Same treatments, sold previously as Neptune Products for the last 25 years in NZ before we rebranded. We're collecting more Kiwi results as we speak.
This stuff is next level. I bought it not expecting much. It really works. Hilux 2011 220000 on the clock. Not running rough but must have a fair bit of carbon buildup. Was running at about 11.2 per 100. Added before a big road trip. At the conclusion of the trip (3700 kms) finished at 8.9 per 100. Fully loaded win 30 kg awning and all camping equipment amazing stuff. Highly recommended.
Great product from CEM I have used before on older machinery and certainly improved hp and worked well. I use in my cars these days to prolong life and keep them running smooth
Would not use anything else. Incredible first results. Use it on multiple vehicles. Recommend to all.
Here's the whole thing in plain English.
Carbon, sludge and friction creep in with every kilometre. Your engine works harder and burns more fuel for it.
Add the treatment to your fuel or oil. That's it. No workshop, no tools, no downtime.
It cleans and protects while you drive. Smoother running, less smoke, more kilometres per tank — results you can feel.
Why we exist
We tried these treatments on our own gear, watched them save us real money, and reckoned New Zealand deserved the same. Born from Neptune Products 25 years ago and backed by over 30 years of Australian know-how — we're not here for slick marketing, just results people can feel.
Treatments that pay for themselves.
