Just changed the oil, but the oil color turned black again in no time? Many car owners immediately assume the oil used is not good. However, the cause is not necessarily from the new oil.
One of the causes take this quickly black is the presence of leftover dirt, grime, sludge, and old oil residue inside the engine. When new oil is added, the dirt still attached to the inner parts of the engine can get mixed back in. As a result, the new oil darkens more quickly.
This condition often occurs in cars that are often late for oil changes, frequently used in traffic jams, rarely serviced, or used cars with unclear maintenance history. From the outside, the engine might look normal. But on the inside, there could still be accumulated old oil deposits.
Actually, oil turning dark is normal because the oil carries dirt from inside the engine. However, if brand new oil turns black too quickly, it could be a sign that the inside of the engine needs more attention.
To help clean out residual dirt before an oil change, you can use AutoGard Engine Flush. This product is formulated to help clean the inside of the engine from old oil residue, sludge, and dirt deposits before new oil is added.
Using it is quite practical. AutoGard Engine Flush is used before changing the old oil. Pour the product into the engine through the oil filler hole, then start the engine and let it idle according to the instructions on the packaging. After that, drain the old oil completely, then fill with new oil according to the vehicle's specifications.
Using AutoGard Engine Flush, ..., the oil change process becomes more optimal because the engine is helped to be cleaned first. New oil can then work in a cleaner engine bay.
So, if your car's oil was just changed but it quickly turns black again, don't immediately blame the oil. The problem might be caused by leftover dirt still remaining inside the engine.
