The “thinness” argument often stems from a misunderstanding of synthetic oil’s superior flow characteristics and viscosity stability.

Addressing Leaks and Consumption

Some users report increased leaks or oil consumption after switching to full synthetic high-mileage oil. While rare, there are explanations.

  • Pre-Existing Leaks: If an engine already has significant leaks, switching to a more detergent-rich synthetic oil can sometimes clean away deposits that were actually *plugging* minor leaks. This makes the existing leak more apparent, rather than causing a new one. The seal conditioners will then work to mitigate this.
  • Aggressive Cleaning: The powerful detergents in Mobil 1 can loosen years of sludge and varnish. While beneficial, in very old, neglected engines, this loosened debris could temporarily block oil passages or further expose compromised seals.
  • Mismatched Viscosity: Using an incorrect viscosity can lead to issues. Always ensure you’re using the weight recommended for your vehicle.

In most cases, any initial increase in leaks or consumption is a temporary symptom of the oil doing its job or revealing a pre-existing issue. If leaks persist or worsen significantly, a mechanical inspection is warranted.

Compatibility Concerns

Another common question is about mixing synthetic with conventional oil, or switching from one to the other.

  • Mixing Oils: While generally not recommended as a regular practice, mixing a full synthetic with a conventional oil will not harm your engine. You simply dilute the benefits of the synthetic. Modern oils are formulated to be compatible.
  • Switching Back and Forth: You can safely switch between conventional, synthetic blend, and full synthetic oils at any time. There’s no need to “flush” your engine. The myth that switching to synthetic will cause leaks in older engines is largely unfounded.
  • Specific High-Mileage Blends: Mobil 1 Full Synthetic High Mileage Motor Oil is fully compatible with other synthetic and conventional oils, but using it exclusively will provide the maximum benefits.

Don’t let compatibility fears prevent you from giving your high-mileage engine the advanced protection it deserves.
