The Protec P1180 was used on a Fiat Punto Evo 1.4 (2010-120000km) & VW Passat 1.8T (2005-180000km) after an oil change using the Protec P1001 for internal engine cleaning and then the Protec P2233VIC was also used. The engines in both cars run differently and you can immediately notice it. The Fiat had a problem with the multiair system and the dealership was asking for 1800€ for repairs, but a used car dealer recommended these products to me because he uses them and yes, the warning light on the Fiat turned off, no problem.

First time in a Citroen c2 vts with 140,000 km (beginning of summer) with very good maintenance, but without having used any other similar product before, except for Liqui Moly Fuel Injection Cleaner and Liqui Moly Hydraulic Lifter Additive. Of course, there was also an oil and filter change, and since they had reached their mileage (30,000+ km), the spark plugs were also replaced. Since the change, about 5,500 km have been covered and due to the new oils (Elf srx 5w40 replacing the LIQUI MOLY Molygen New Generation 5W-40), there is a significant difference in the engine's performance for the better, less noise, smoother movement, and better gear changes.

For it to function and perform correctly, the car's engine needs to reach normal operating temperature. It is added either to the old oil or to a new, low-priced one (after removing the old one) that is only used for flushing. The second option is even better, even if it costs more.

It remains in the engine with the engine running for 10-15 minutes (if the car has over 100,000 km, it is better to leave it for 15 minutes) without the car moving.

When each task is completed, the car needs to warm up for 5-6 minutes and then be driven for 30-40 kilometers at a continuous speed (110-120+) before being immobilized. A drive on the national or Attiki highway is necessary.

It is an additive from a German company specializing in such products and with excellent reviews, which also gave me the incentive to research and choose it.

It is indeed an excellent cleaner that is worth its money.
