Boosting your car can be an exciting way to add more power to your engine, but it comes with several factors to consider. The Motor Oil Geek on YouTube recently published a video showing the effects of adding boost to an engine, specifically focusing on how it affects the engine oil. In the video, an LS-based V-8 engine designed for drag racing was tested on a dyno both with and without boost, and the oil was analyzed to see how it handled the added pressure.
Effects of Boost on Engine Oil
When the engine was tested without boost, the oil maintained a healthy viscosity and the correct amount of additives throughout the dyno runs. However, once a supercharger was added to the system, things changed. Boosting the engine means more fuel is being pushed into it, which results in more fuel ending up in the oil. This dilutes the oil, causing a decrease in viscosity. This means that even though the same oil is being used, the engine is not running at the correct weight.
Result of Incorrect Viscosity
The consequences of incorrect viscosity are increased wear and tear on the engine. The analysis of the oil used in the boosted V-8 showed significant increases in wear metals like iron and copper. This indicates that over time, the engine would fail much sooner than its naturally aspirated counterpart because the oil was not designed to handle the added boost.
Lessons Learned
The lesson to be learned from this experiment is that it is crucial to ensure that your engine oil can withstand the added pressure of boost before installing a turbocharger or supercharger. Using the wrong oil can lead to serious consequences for your engine and potentially shorten its lifespan. It is important to do your research and consult with experts to determine the best oil for your boosted engine to protect its longevity and performance.
Consulting with Professionals
If you are unsure about which oil to use for your boosted engine, it is always a good idea to consult with professionals who have experience with performance modifications. They can provide valuable insights and recommendations based on your specific setup and driving habits. Investing in the right oil for your boosted engine can make a significant difference in its overall health and performance, allowing you to enjoy the benefits of added power without compromising the longevity of your engine.
Conclusion
In conclusion, adding boost to your car can be an exciting way to increase power, but it is essential to ensure that your engine oil can handle the added pressure. Using the wrong oil can result in decreased performance, increased wear, and potentially costly repairs. By taking the time to research and choose the right oil for your boosted engine, you can protect your investment and enjoy the full benefits of increased power without compromising the health of your engine.
