There is a buildup of muck in the engine and oil filter.

Presently, my automobile is afflicted with engine sludge, and I received advice against doing an engine flush due to the potential harm it may bring to the oil filter. Could you provide further information about the subject and specify the location of this particular part? Frankly, I possess little knowledge on the subject.

The oil filter is located in an elevated position.
To effectively clean the engine, it is recommended to add one quart of automatic transmission fluid (ATF) to the engine oil. After adding the ATF, drive the vehicle for a duration of 10-15 minutes. Following this, proceed to replace both the oil and the filter.

ATF does not possess any cleaning properties for an engine. It is of inferior quality compared to normal oil.

It gained recognition as a cleaning agent during the 1940s, a time when whale oil was still in use. Whale oil has a significant amount of esters, which have the ability to dissolve deposits.

ATF produced after the prohibition of whale oil (about 1975) lacks esters, which renders it ineffective for cleaning purposes. Indeed, transmissions remain free from contamination due to the absence of combustion byproducts, rather than the superiority of the fluid. The ATF is essentially a lubricating oil plus additives, specifically formulated to have a viscosity grade of 5W. I really want for this myth to cease to exist.

Returning to the original topic - if there is sludge present in your engine, it is advisable to clean it gradually. Introducing a significant amount of solvent, such as diesel fuel or other substances, into your engine poses the danger of dislodging substantial deposits of sludge, which may result in engine damage and blockage of the filter with such sludge.

It is advisable to clean at a leisurely pace. Consider using a product such as Liquimoly engine flush. Prior to a transition, you introduce it, let the engine to run without load, and thereafter replace the oil. It is specifically engineered to disintegrate solid deposits, and the resulting dissolved substance in your filter will be replaced after you complete the flushing process and replace your oil. Under no circumstances should you drive with the flush in your engine. Adhere to the instructions provided on the can.

If you need to really cleanse your engine, there are specific oils available that use alkylated naphthalenes and poly alpha olefins. These are contemporary and costly base oils that surpass even synthetic oils in terms of their cleaning efficacy, outperforming even whale oil.

Valvoline just introduced a new product called Restore & Protect to the market. This product is part of Valvoline's global line of offerings.

The oil firm owned by my buddy produces a product with similar functionality, and their engine cleaner is effective, however at a gradual pace, which aligns well with your requirements.

Once again, adhere to the instructions provided on the label.

Ultimately, the crucial factor in oil is its specification, rather than the viscosity or base stock. The term "synthetic" has little to no significance.

To ensure compatibility, you should choose an oil that adheres to the MB 229.5 standard. Any oil fulfilling this need will suffice. There are many brands and viscosities available that satisfy this criterion, so you have a range of options. As long as the oil satisfies the MB 229.5 specification, it is a suitable choice. Observe this compilation: Mercedes-Benz Operating Fluids

An exceptional option is the Mobil 1 0W40 FS, which stands out among the top choices. It complies with the 229.5 standard and may be easily found at Wal-mart, Costco, or Amazon for a similar price to other products. An excellent selection.

Indeed, it is advisable to use a high-grade synthetic oil as a preventive measure to circumvent these issues from arising in the initial stages.

Lastly, use the white "fleece" filters. If your engine has sludge, it is advisable to replace your oil every 5,000 miles for a considerable period, preferably the following 20,000 miles, in order to facilitate the cleansing of the engine.

I do not agree. The ATF is ineffective. I have consistently used automatic transmission fluid (ATF) at every instance of oil change for my Volvo 850, spanning a distance of 200,000 miles. I had a total of 350,000 units of currency when I disassembled the engine due to a malfunctioning timing belt. The engine was immaculate. It is effective. This engine is renowned for its propensity to accumulate muck. In the absence of adequate maintenance

own a total of five Volvo automobiles at now. 5.

I have a deep understanding of the Volvo difficulty, which pertains to the PCV system.

The key aspect with Volvo, as well as with Mercedes, is to use an oil that adheres to the appropriate specifications.

This indicates that the design of the product is intended to be simple enough to endure the acids produced by the byproducts of combustion for the whole drain period. Additionally, it must fulfill other performance criteria such as high-temperature high-shear (HTHS) stability, shear stability, and detergency. Detergency, in essence, quantifies the oil's capacity to retain dirt in a suspended state. However, your engine does not possess the capability to remove filth, since it is not designed to function as a washing machine.

As previously said, an acquaintance of mine is the proprietor of an oil corporation. I have acquired extensive knowledge from him about the components of oil. There is absolutely no cleaning efficacy whatsoever in any ATF product. The use of ATF and the presence of a clean engine exhibit association, nevertheless, they do not establish a causative relationship.

Only if you were using an ATF containing whale oil (which is doubtful) or one that is rich in esters (also unusual, but not impossible).

The solvency of the product rests in the esters, alkylated napthalenes, or PAO, rather than the presence of transmission fluid. Therefore, providing a recommendation for general transmission fluid without knowledge of whether it contains a crucial cleaning component is an inadequate suggestion.

Additionally, your Volvo routine was proactive.

The well-known dispute over motor oil. Laughing out loud. In my perspective, whatever motor oil you choose to use will enough. Walmart offers Super Tech oil for purchase. The M113 engine is durable, and many fourth and fifth owners have mistreated these cars by completely disregarding oil changes, but the vehicles still manage to accumulate well over 200,000 kilometers.

Undoubtedly, the most effective measure to avoid sludge formation is to adhere to a consistent schedule of oil changes. However, it is important to note that this does not necessarily imply that the oil has to be changed every 3000 miles. However, oil changes at intervals of 5000 to 7500 miles are quite acceptable. Engines that are contaminated often have not had oil changes at intervals of 20 or 30,000 kilometers. Consequently, it is the reason why they have been sludged up.

Both ATF and liquid Molly engine flush may effectively do the task. Similar to any engine oil recommended by your local shop as suitable. It is irrelevant if you use 30 weight, zero W-40, or 20 W-50.

If you really want to eliminate the sludge, it is necessary to detach the valve covers and thoroughly cleanse the upper section of the engine. These engines often have valve cover leaks, making it convenient to address this issue when replacing the valve cover gasket.
