Is Recycled Motor Oil as Good as New Oil?

Many car enthusiasts and mechanics often debate whether recycled motor oil is suitable for vehicle engines. While some claim recycled oil can be just as good, others strongly advise against using it. This article aims to clarify the difference and whether it is safe to use recycled motor oil in modern engines.

My Experience: Why Recycled Oil Isn't as Good

In my experience, recycled motor oil is not as good as new oil. For instance, when my parents used the old 20W50 motor oil in their car, it seemed to burn the piston rings out. This was a significant issue that they had to deal with. Additionally, using this oil in a 2-stroke motorcycle engine with a wet clutch was problematic. A good quality 20W50 oil is specifically formulated to prevent slippage in such engines. Recycled oil, however, did not differentiate and exhibited the same formulation, leading to similar issues.

Why Recycled Oil Should Definitely Not Be Used

Absolutely, unequivocally no! To put it bluntly, there are very few situations where you should consider using recycled motor oil. The primary reason is that it may not meet the high standards of new, virgin oil. Recycled oil is essentially used motor oil that has been refined and cleaned, but it still contains impurities and contaminants.

There are concerns about dirt particles, cancer-causing chemicals, and worn-out additives. These components can degrade engine performance and potentially cause long-term damage. Even if the oil is reprocessed, there is still a risk of exposure to harmful substances that can accumulate over time.

Exceptional Cases: Diesel Cars Converted to Run on Grease

The only possible scenario where using recycled oil might make sense is in a diesel car that has been converted to run on grease. In this specific situation, the recycled oil could potentially be used as a fuel. However, it is important to note that this is not a standard or recommended practice for most vehicles.

The term "recycled oil" can be ambiguous. If it refers to used motor oil that has been reprocessed, there might be a marginal improvement in quality. However, why take the risk of potentially damaging your engine by using this type of oil when you can opt for the safer and more reliable option of new, virgin oil?

Alternative Options: Chainsaw Oil

Another angle to consider is chainsaw oil. In this context, chainsaw oil, which is technically reprocessed oil, can work well in certain applications where the hydraulic and lubrication needs are not as stringent as in car engines. However, even in this case, it is crucial to follow the manufacturer's recommendations and not oversimplify the choice of oil.

For car engines, the best practice is to stick with new, high-quality motor oil that is specifically designed for your vehicle’s make and model. This ensures optimal performance, extended engine life, and safety. Investing in premium oil may seem like a small cost in the grand scheme of vehicle maintenance, but the benefits outweigh the risks.

Conclusion

In summary, while recycled motor oil might seem like a cost-effective alternative, it is generally not recommended for conventional vehicle engines. The risk of long-term damage to your engine is too high, and the cost of potential repairs can be prohibitive. It is always better to invest in new, high-quality motor oil that is specifically formulated for your vehicle. This ensures not only the best performance but also the longevity and reliability of your engine.
