Prerequisites:

A variant of Mécacyl CR, Mécacyl CR-P offers effective care for all hydraulic tappets. It reduces tappet noise and knocking from the very first use.
Mécacyl CR-P is a complementary hyper-lubricant for all petrol, diesel, hybrid and gas vehicles. It is more specifically aimed at vehicles with noisy or knocking hydraulic tappets. It can be used in high kilometre engines if  Mécacyl CR is not effective against tappet problems.
If your vehicle is in perfect conditions, has always had regular maintenance, never shows any abnormal consumption or leakage of oil or coolant, you may absolutely use 
Mécacyl CR-P with excellent results.


Frequency of use:

Follow the manufacturer’s recommendations.

Max. 15,000 km to continue to get the best results.

If the manufacturer recommends an oil change every 20,000 km, Mécacyl CR may be added.

In used vehicles:
- Vehicle from 50,000 to 100,000 km: Do an oil change after adding 
Mécacyl CR-P at 5,000 km and then do oil changes at the normal intervals with Mécacyl CR-P each time.

- Vehicle from 100,000 to 150,000 km: Do an oil change at 3,000 km; an oil change at 5,000 km and then oil changes at the normal intervals with Mécacyl CR-P each time.

- Vehicle from 150,000 to 180,000 km: Do an oil change at 3,000 km; an oil change at 5,000 km and, if necessary, an oil change at 8,000 km then oil changes at the normal intervals with Mécacyl CR-P each time.

- Vehicle beyond 180,000 km: Ask us.

For oil changes that are close together, 15w40 oil (vehicles produced before 2000) or 10w40 (vehicles produced after 2000) is perfectly fine. Continue doing oil changes at normal intervals, using CR and the oil of your choice.


In LPG vehicles:
- The same is true for petrol or diesel vehicles.

Every 10,000 to 15,000 km maximum or every 12 months.
Do an oil change approximately 5,000 km after adding Mécacyl CR-P  for the first time, if necessary, and then do oil changes at the normal intervals with Mécacyl CR-P each time.


For diesel vehicles:
- Vehicles with a particle filter: 
Mécacyl CR-P can be used in vehicles with a particle filter. The aim is always to protect the particle filter. Observe the precautions above.

- Vehicle with EGR valve coolant or exchangers:

Mécacyl CR-P can be used in vehicles with EGR. The aim is always to protect the EGR.


Specific situation:
Some diesel vehicle models produced after 2005 are equipped with specific EGR valves (around 6% of all diesel vehicles on the road). These EGR valves are coupled to 1 cooler or exchanger (EGR valve cooled by coolant). If your vehicle is equipped with this type of EGR valve, don’t use
Mécacyl CR-P.

Other EGR valves can be used.


Use:

Mécacyl CR-P is to be used with clean oil after an oil change. If it couldn’t be added after the oil change, it can be added a maximum of 3,000 km after an oil change.
Dosage: 2-3% of the oil quantity; in other words, one 100 ml bottle for 4 to 5 litres of oil.

  1. The engine must be hot; in other words, at operating temperature.
  2. Pour Mécacyl CR-P directly into the oil tank.
  3. Run or turn on the engine for a minimum of 10 minutes.

Depending on the number of kilometres or the vehicle wear, 1 to 2 oil changes close together may be appropriate (see Frequency of use).


Please note: white smoke will come out of the exhaust during the first 10 to 15 km after adding Mécacyl CR-P. This is completely normal: Mécacyl CR-P eliminates water and oxides; a dry engine wears out faster.


Type of oil: 

For faster blending, 10W40 or 15W40 oils are best for 90% of all uses.

In general, all petroleum-based polymer oils are compatible with MECACYL whether they are multi-grade, semi-synthetic or synthetic (5W40, 5w30...).


Contraindications:

-          Abnormal oil consumption.
-          Abnormal coolant consumption.
-          Very worn, old engines which are about to break down.
-          Silicone, paraffin and graphite oils.
-          Non-petroleum polymer-based oils.
-          A diesel car equipped with an EGR valve cooled with coolant.
-          Previous additive use.


Advice:

If you buy a used vehicle in good general conditions, start with Mécacyl CR-P.
If you don’t notice any results or simply poor results, use Mécacyl CR-P upon the next oil change.

 

Benefits:

-          Tappet silence (knocking, noise...).
-          Protects the engine.
-          Less fuel consumption (8 to 15%).
-          Less pollution.
