The owner wanted to give it a try for a long time, so this time he took advantage of the 5 W-kilometer maintenance to clean the interior of the engine.

This is a V6 3.0 Audi, which has so far traveled 5W kilometers to experience internal cleaning of the engine.

It uses 6 liters of German Remo’s 0W-40 engine oil and a bottle of Remo’s internal cleaning agent.

Engine internal cleaning agent is a product developed to solve the problem of sludge, glue, carbon deposit, paint film, dirt and other deposits formed inside the lubrication system. It consists of multiple components with very strong cleaning ability and is an additive that can automatically clean the internal system of the lubrication system.
Add the engine interior cleaning agent to the engine crankcase and complete the cleaning process with the oil flowing during the engine operation, which will dissolve the colloid and make the deposits bonded together loose and fall off. Deposits such as paint film, carbon deposits, and sludge on piston rings and piston skirts will be completely removed.
I won’t say much about the detailed introduction, but the introduction and usage instructions are all in the figure.

The point of note is: 5 liters of engine oil and a bottle of cleaning agent are enough, which means that most vehicles need only one bottle when in use.
Before changing the oil, add a bottle of cleaning agent to the engine and idle for 10 minutes.

For imported Limo 0W-40 engine oil, various data on the outer packaging barrel are clearly marked.

Let’s not talk about more, let’s start. First add the cleaning agent to the old engine oil and start idling for 10 minutes.

After idling is completed, remove the oil bottom screws to allow the old oil to be drained.

The extraction method is not recommended for the oil discharge method here. It is best to use the high-pressure air blowing method, because the cleaned deposits will be filtered out by the oil filter according to the oil circulation, or deposited in the oil pan, and the oil filter will be directly replaced., and the accumulation at the oil pan is difficult to drain when we extract it. On the contrary, the blowing and blowing method has a better effect.
Benefits of internal engine cleaning (copied by Baidu）：
It can efficiently clean carbon deposits, gums and other harmful substances inside the engine.
It can prevent combination and remove oil films and sludge formed by old engine oil to avoid reducing the performance of new engine oil.
It can improve the efficiency of the engine, thereby reducing noise, and also reduce fuel and oil losses.
Neutralize long-term harmful acids generated inside the engine.
Ability to clean crankcase PVC valves. Ability to clean hydraulic lifters and valve lifters.
It can clean the engine’s lubrication system, reduce engine temperature, enhance oil mobility, and improve lubrication efficiency. The engine can be prevented from burning oil.
The cleaning agent inside the engine is very simple to use. The interior of the engine can be maintained and cleaned without disassembling the engine, and the interior of the engine can be cleaned.
