The Incredible Amount of Horsepower You Can Unlock By Running Your Engine Low on Oil



Are you looking to increase the power of your engine? While there are obvious upgrades like air intakes and forced induction, one often overlooked factor is the amount of oil in your engine. Lake Speed Jr. from The Motor Oil Geek YouTube channel recently conducted a test with Ben Strader from EFI University to demonstrate the impact of oil capacity on engine power. Using a Chevy LS-based V-8, the initial test with only five quarts of oil in the pan resulted in an impressive 649 horsepower, but dangerously low oil pressure. Adding more oil gradually decreased the power output, with 589 horsepower achieved with nine quarts of oil, but with perfect oil pressure.

This test highlights a concept that both club racers and professionals have known for decades – running the recommended amount of oil ensures engine safety, but reducing the amount of oil can help maximize power. Less oil means less resistance for the engine internals, allowing for more power to be extracted. However, running less oil also increases the risk to your engine, so it’s crucial to find the balance between power and safety. By determining the exact amount of oil your engine needs to run efficiently, you can optimize performance without compromising engine health.

The key takeaway from this test is that oil capacity plays a significant role in engine power. By understanding the relationship between oil volume, oil pressure, and power output, enthusiasts can fine-tune their engines for optimal performance. Whether you’re looking to gain an edge in a drag race or on a road course, adjusting the oil capacity can make a noticeable difference in power. It’s essential to experiment cautiously and find the right balance that maximizes power while maintaining engine reliability.

While adding more oil to your engine may seem like a logical choice to ensure proper lubrication and cooling, this test demonstrates that excess oil can actually hinder performance. By reducing the amount of oil in your engine to the minimum required for optimal operation, you can minimize internal resistance and maximize power output. This concept may go against conventional wisdom, but the results speak for themselves – less oil can equal more power.

In conclusion, oil capacity is a crucial factor in engine performance that is often overlooked by enthusiasts. By conducting tests like the one performed by Lake Speed Jr. and Ben Strader, car owners can gain valuable insights into the impact of oil volume on power output. Finding the optimal balance between oil capacity, oil pressure, and power output is essential for maximizing engine performance while ensuring reliability. Experimenting cautiously and monitoring engine health is key to unlocking the full potential of your engine through oil optimization.
