A YouTuber conducted an experiment to find out what happens to engine oil after half a century in its original container. The results are surprising and highlight the importance of respecting engine oil expiration dates, something that is often overlooked by drivers and mechanics.
The importance of oil changes and oil quality
Oil changes are a crucial maintenance operation for the longevity of a vehicle. Experts recommend:
Using expired oil can be more damaging than skipping an oil change. Unfortunately, many motorists and mechanics ignore the expiration dates on oil containers, which can lead to costly repairs down the road.
The Lake Speed โโJr. Experience
Lake Speed โโJr., known on YouTube as “The Motor Oil Geek,” decided to test the effects of expired oil on an engine. His experiment consisted of:
The results of the analysis
Laboratory analysis revealed worrying results:
Surprisingly, the oil in the plastic can (Valvoline) was found to be more degraded than that in the older metal can (Mobil1).
The breakdown of oil over time
The experiment highlighted several degradation phenomena:
These alterations are particularly marked in plastic containers, which are more sensitive to temperature variations.
The real life of engine oil
Contrary to popular belief, engine oil has a limited lifespan, even when not in use:
The consequences for motorists
This experience highlights the importance of:
Ultimately, using expired oil can be a false economy, potentially leading to costly breakdowns. It is therefore essential to raise awareness among motorists and professionals of the importance of respecting the expiry dates of engine oils to ensure the longevity and optimum performance of vehicles.
