The Last Catch Can System You’ll Ever Need: Tracy Lewis Performance

Let’s be clear: GDI engines are vulnerable. Unlike traditional port injection engines, GDI setups inject fuel directly into the combustion chamber. That efficiency comes at a cost:

• Excessive blow-by gases force fuel and vapor past the piston rings into the crankcase.
• Oil dilution happens as raw fuel mixes with engine oil, stripping away viscosity.
• Valve coking and carbon buildup form rapidly since there's no fuel washing the back of intake valves.
• LSPI (Low-Speed Pre-Ignition) becomes a serious threat—leading to violent engine knock, piston damage, and catastrophic failure.

And this isn’t a brand-specific issue. It affects every single GDI engine on the road, no matter the make or size. The 6.2L GM engine just happens to be the one making headlines—but the problem is industry-wide.

Not Just for GDI—All Engines Benefit

While GDI engines have the most urgent need, non-GDI engines can benefit too. Reduced oil vapor, cleaner combustion, and more efficient crankcase ventilation lead to:

• Cleaner engine internals
• Better fuel economy
• Longer oil life
• More consistent power delivery

Any gasoline engine new or classic—can benefit from the protection and performance enhancement the Tracy Lewis system delivers.

Built in the U.S.A. — Backed for Life

Every Tracy Lewis Catch Can is manufactured in the United States using U.S.-sourced materials and aerospace-grade construction standards. This isn't mass-produced, overseas equipment. This is serious, American-made performance gear that works as hard as your engine does.

And it’s backed by a limited lifetime warranty, with top-tier customer service before and after the sale. We don’t disappear after checkout. We're with you every step of the way—from selecting the right kit to post-install questions and support.

Our patented crankcase evacuation catch can system is the ONLY system on the market that solves these problems at the root. Tracy Lewis Performance is the only company with verified long-term oil analysis data—provided by real customers—showing that our system significantly reduces fuel dilution, restores oil viscosity, and prevents the chain of failures that lead to engine damage. No other system on the market does this. Period.

This patented system is actually a true full time vacuum crankcase evacuation system. Unlike the GM recall fix of changing the oil from the owners manual recommended 0w20/5w20 weight, they simply change to a 0w40 weight. While that does help some on combating the oil dilution cause of the engine failures, it is not a solution but simply a "Band Aid" approach to get the end user past the warranty period. It does nothing to address the cause. Just treats the symptoms (as the 8L90e transmission fluid flush is only treating the symptom and not the cause) as the higher viscosity can still maintain some protection vs the 0w20. But the same amount of raw fuel is entering so nothing is done to prevent the dilution.

Our system actually brings in fresh, filtered, and MAF metered air into one bank or portion of the crankcase to flush and make up for the foul contaminant laden vapors being evacuated out the opposite bank or portion of the crankcase. And it does so full time vs the stock system that only relies on part time vacuum. So at all times the constantly entering excessive raw fuel and other contaminants produced during the combustion process are flushed and removed before they have a chance to settle and mix with the oil. So oil is not bombarded by these wear and damage causing substances. All while maintaining a closed emissions system.

Oil stays cleaner longer, wear is greatly reduced, and not only is engine life extended to near port injection engines of the past, but as we also trap and contain oil vapors that cause spark knock and knock retard, the engine maintains optimum ignition spark advance so the engine runs at peak efficiency giving 10% plus increase in fuel economy. And where the average "catch can" design only traps a small percentage of the total suspended contaminants, this system traps 90-95%, so almost nothing gets past.

One of our longtime customers put our system through an independent, long-term oil analysis. The result? Dramatic reduction in fuel content in the oil. Stable viscosity over time. Cleaner internals. Fewer LSPI events. More stable performance under stress.

No other catch can system has shown results like this.
