If you notice your car giving off bluish or greyish smoke from the exhaust and you keep having to top up the oil level, your engine is asking for help. These symptoms usually point to advanced wear in the piston rings and valve guides, which lets oil leak through and burn in the combustion chamber.
The good news is you don't always need an expensive mechanical repair right away. Superkote 2000 Smoke Free is a dual-action corrective treatment specifically designed to seal the gaps caused by wear, stop the oil from burning and eliminate the smoke, helping you pass the emissions test and extending your vehicle's service life.
Quick diagnosis: what is your exhaust smoke telling you?
To find out whether this product is the right solution for you, you first need to understand your car's "language". Smoke colour is the best indicator of what's going wrong under the hood. While black smoke points to excess fuel and dense white smoke is usually coolant, blue smoke is the unmistakable sign that you're burning oil due to internal wear.
Here's how to tell them apart so you don't spend money on the wrong product:
-
Blue or bluish-grey smoke: this is what Smoke Free targets. Oil is getting into the cylinders because the rings or valve seals are worn. Along with the smoke, the oil level drops quickly.
-
Black smoke: the engine is injecting too much fuel (rich mixture). It could be dirty injectors, a clogged air filter or sensors, but it isn't oil consumption.
-
White smoke (vapour): if it disappears quickly in cold weather, it's normal condensation. If it's dense, persistent and smells sweet, you're burning coolant (possibly a blown head gasket).
If your diagnosis matches blue smoke, your engine has internal clearances that need to be filled.

How does the Smoke Free treatment work? (the simple science)
Unlike cheap "thickening" additives that just make the oil denser (making cold starts harder), Superkote 2000 Smoke Free uses a dual-action technology:
-
Selective viscosity sealing: improves the oil's viscosity index at high temperatures, creating a film that fills the excess gap between piston and cylinder and stops oil from escaping into the combustion chamber.
-
Built-in metal treatment: contains a percentage of the original Superkote 2000 Anti-Friction formula. It doesn't just plug the leak: it chemically treats the worn metal, smooths out running and reduces noise.
Essentially, it acts as a "liquid rebuilder" that restores the cylinders' tightness and recovers lost compression.
4 signs your engine urgently needs this treatment
This product isn't for new cars; it's medicine for veteran engines. If you recognise any of these 4 points, it's time to apply it:
-
Failed the emissions test: if you were rejected for "opacity" or high emissions and the smoke is oil-related, this treatment is usually the fastest and cheapest solution before the re-test.
-
"Oily" or dirty spark plugs: if they come out wet or black with oil when you replace them, lubricant is getting somewhere it shouldn't.
-
Constantly topping up the oil: if the level drops every few kilometres and you don't see puddles on the ground, the engine is "drinking" the oil.
-
Loss of power on hills: with worn rings, compression escapes; if you lack power on inclines, you need to improve the cylinder seal.

Application guide: how to use it to pass the emissions test
Unlike other additives you simply pour in and forget, Smoke Free needs a couple of details to work at 100%, especially if your goal is to cut emissions before the inspection.
-
Warm up the engine: mandatory. The product is viscous; it needs the engine at operating temperature (15-20 min of driving) to blend evenly.
-
Add the product: with the engine off but still warm, open the filler cap and pour in the entire contents of the bottle.
-
Standard dose: one bottle for standard cars (4 to 6 litres of oil).
-
Large engines: for trucks or heavy machinery, check the ratio (≈10% of capacity).
-
Drive to mix it in: start the engine and drive gently for 10-15 minutes so the formula reaches the rings and starts sealing.
⚠️ Important warning: Do NOT use on new or recently rebored engines (under 6,000 km). Its purpose is to compensate for clearances caused by wear; a new engine has none, and increasing viscosity would be counterproductive.
Smoke Free vs. Metal Treatment: which one do I need?
This is the most common question among our customers. Although both protect the engine, they work in opposite ways:
Superkote 2000 Metal Treatment (the vaccine) — link: /collections/tratamiento-metal
-
Function: preventive and anti-friction.
-
Who it's for: new cars, used cars in good condition, or high-mileage taxis.
-
Duration: one application lasts 80,000 km (permanent).
-
Viscosity: does not thicken the oil.
Superkote 2000 Smoke Free (the medicine):
-
Function: corrective and sealing.
-
Who it's for: older cars that use oil, smoke, or have lost power.
-
Duration: renew with every oil change (5,000-10,000 km).
-
Viscosity: increases density to seal leaks.
Can I mix them? Yes. Smoke Free already includes a percentage of the anti-friction formula. For maximum protection on a very worn car, use Smoke Free to "seal" and the Metal Treatment to "shield" the rest of the parts.

Frequently asked questions about the Smoke Free treatment
We answer the most common questions so you can apply the product with full confidence.
Does it work in diesel and petrol engines?
Yes, it's effective in both. Ring and valve guide wear is mechanical and works the same regardless of fuel type.
Can it repair a broken ring or a crack?
We're honest: this is a chemical treatment, not a miracle mechanic. It fills clearances caused by natural wear. A physically broken part needs a workshop repair.
When will I see results?
Almost immediately. After mixing with the hot oil and driving for 15-20 minutes, you'll notice a drastic reduction in smoke and smoother, quieter running.
Do I need to repeat the treatment with every oil change?
Yes. Unlike the Metal Treatment (permanent), Smoke Free degrades along with the old oil. In heavily worn engines, add a new bottle with each oil change.
To wrap up…
Seeing smoke coming out of your car doesn't have to mean the end of its service life or a four-figure workshop bill. Older engines often just need a little extra help. Superkote 2000 Smoke Free is that "second chance" to keep driving strong, pass the emissions test without worry, and stop burning oil.
It's the most cost-effective solution before considering opening up the engine. Try it and feel the difference from the very first start.
