Welcome To Gavarino Engineering LLC

 Extend The Life Of Your Oil.   Extend The Life Of Your Engine.


The mythical every year 3,000 mile oil change is just that, “mythical”.   With modern oil and greater filtration, why would you throw away perfectly good oil and money?


Bypass oil technology is used in every industrial and commercial industry in the world to minimize oil contamination. *We are the first to adapt it to fit most Ferrari models.


Two sample bottles are included to perform before and after oil analysis. If your not 100% satisfied we will refund your money including the cost of your oil analysis.


With basic mechanical skills and no permanent modifications, you can install our system in a couple of hours.


Running the cleanest oil possible thru your engine is the best insurance you will ever buy.

How Do We Extend The Life Of Your Oil & Engine?

  By reducing the size and volume of the contaminants circulating in your oil.

Industry Standard Micron Size

Factory installed filtration only filters particles from 20-40 microns in size.

Gavarino Micron Size

The Gavarino Filtration System effectively filters particles down to 2-4 microns in size.

The Under Filtered Oil Problem

An engine is a contaminate manufacturing device. Contaminates enter your engine oil in many ways. Leakage past the piston rings, blow-by, premature or late combustion in the cycle, dust and dirt from outside air. Factory installed filters capture particles in the 20-40 micron range at best, leaving the smaller particles to circulate in your oil stream. When the additive package in your oil becomes overwhelmed  with these tiny particles they eat away at the surfaces inside your engine. With your oil left insignificantly filtered,  your engine continually generates more and more wear particles until ultimately it causes an internal component failure.

Our Solution

The Gavarino filtration system captures particles in the 2-4 micron range and operates strictly as a closed-loop system. We use engine oil pressure (1-2psi) to flow a small percentage of your oil through a synthetic media and then return the clean oil back into your engine. This flow of oil through our system is minimal and has no impact on the volume of oil required to properly lubricate your engine. This flow also allows the complete volume of engine oil to be circulated continuously, thus substantially reducing the level of contaminates found in normally filtered oil. You’ll be impressed with the results.

Testing and Simplicity

Quantum Physics and space travel are complicated.  We design and test our systems with simplicity in mind; it doesn’t have to be complicated to be effective.


Our system only runs on 1-2 lbs of pressure and will never disrupt or starve your engines primary oiling system.


Our systems are custom manufactured to fit your specific vehicle, it’s not a one size fits all kit.


Two sample bottles are included to perform before and after oil analysis. If your not 100% satisfied we will refund your money including the cost of your oil analysis.


Our filter head was designed to accommodate a variety of filters should you choose to use a different manufacturer. We currently use an Amsoil Ea, 2-micron filter on every one of our systems.
