Product Information
Full details
Carlube Stop Smoke is an ideal maintenance solution for owners of older, high-mileage vehicles who are struggling with oil burning and visible blue exhaust emissions. This concentrated polymer treatment seals gaps between worn engine parts to improve compression and reduce oil consumption, though it is specifically intended as a corrective measure for engine wear rather than a fix for mechanical failures.

FAQs
Can I use Carlube Stop Smoke in a brand-new engine?
This product is specifically formulated for high-mileage engines with wear. It is not recommended for new engines that do not yet have component wear.
How often should I add this treatment?
It is most effective when added during every oil change to maintain the seal integrity of engine components.
Will this harm my catalytic converter?
When used according to the instructions, it is designed to be safe for standard engine operation and emissions systems.
Can I use this with any viscosity oil?
Yes, it is compatible with all standard automotive oil viscosities.
Does it fix knocking sounds?
No, Carlube Stop Smoke is designed to address oil burning and compression issues, not mechanical knocking or rod play.
Is 300ml enough for my engine?
One 300ml bottle is sufficient for most standard passenger vehicle engines with an oil capacity of up to 5 liters.
Troubleshooting
Engine still smokes after application
The treatment takes time to circulate; ensure you have driven the vehicle for several miles to allow the polymers to seal gaps. If smoke persists, mechanical inspection may be required.
Oil level is too high
Drain a small amount of oil to bring the level back to the recommended mark on the dipstick to prevent internal pressure issues.
Pros and Cons
Pros
- Significantly reduces blue exhaust smoke in older engines
- Easy to apply without specialized tools
- Compatible with both synthetic and mineral oils
- Improves engine compression in high-mileage vehicles
- Helps lower overall oil consumption between service intervals
Cons

Setup, Compatibility & Care
This product is highly versatile and requires no complex setup. It is fully compatible with all common automotive engine oil types (mineral, semi-synthetic, and full synthetic). To apply, remove the oil filler cap, pour the contents of the 300ml bottle into the engine, and replace the cap securely. To ensure maximum efficacy, add the treatment during a scheduled oil change to allow the polymers to integrate with fresh oil. For ongoing maintenance, check your dipstick weekly to monitor oil levels and ensure the engine remains within manufacturer specifications.
