Product Information

Full details

The K2 Doctor Car Spec 443ml is an essential maintenance additive designed for owners of high-mileage or worn vehicles looking to quiet engine noise, stabilize compression, and mitigate excessive oil consumption. It is ideal for drivers operating under demanding conditions like heavy city traffic or frequent cold starts; however, it should be viewed strictly as a performance aid for wear-related symptoms rather than a permanent mechanical fix for catastrophic failures like broken gaskets or damaged turbochargers.

FAQs

Can I use this with synthetic oil?

Yes, K2 Doctor Car Spec is fully compatible with both synthetic and mineral-based engine oils.

Will this fix a broken gasket?

No, this product is designed to reduce friction and wear symptoms. It cannot repair damaged seals or gaskets.

Can I use this in a diesel engine?

Yes, it is suitable for petrol, diesel, LPG, and CNG engines.

How much do I add for a 6-litre engine?

Since one bottle treats 2 to 5 litres, you would typically use more than one bottle, but always check the dipstick to ensure you do not exceed the maximum fill level.

Can I use it in my transmission?

Yes, it is safe to use in GL-5 gearbox oils at a ratio of one bottle per 3 litres.

How often should I add this?

It is recommended to add the treatment during each engine oil change to maintain the protective benefits.

Troubleshooting

Engine oil level is already at the maximum capacity.

Do not add the treatment. Drain a small amount of oil first or wait until your next oil change to include the additive to prevent overfilling.

The engine still produces excessive smoke after treatment.

This may indicate a damaged seal, gasket, or turbocharger, which this product cannot repair. Consult a mechanic.

Setup, Compatibility & Care

Before using K2 Doctor Car Spec, ensure the engine is at operating temperature for better mixing. Add the content of one 443ml bottle to the existing engine oil, ensuring the total oil level does not exceed the manufacturer's maximum mark on the dipstick.

For Engines: Use one bottle per 2–5 litres of oil.
For Gearboxes: Use one bottle per 3 litres of GL-5 gear oil.
Care: Always check your vehicle manual to ensure the oil viscosity requirements remain within the manufacturer's specified range after adding the treatment. Do not use this product to mask symptoms of severe engine failures, such as a blown head gasket, as these require immediate professional mechanical intervention.
