Hey all,
Want to share some guidelines on caring for your catchcan. First, as we have shown many times, the average can only traps between 15-30% so choosing the right one is critical. Want to test yourself? Take any of the "billet" cans (moroso, Billet xxx, the MM, etc. and install a Elite E2-X or E2 Catch Can inline AFTER the other can and run 1000 miles and check both. You will find the E2 and E2-X will trap as much or more that got past the first can, no matter what the brand claims. So effectiveness is key. Now do the same test in reverse and see almost nothing gets past these effective designs.
Next, NEVER let your can get more than 1/3 full. For small cans with only 2-3oz capacity, that can happen in short order. DO not choose by appearance alone or ease to fit as it is not going to prevent the issues you wish to prevent. If you allow the can to fill more than 1/3 full, then what has been caught begins to be drawn through making it useless.
With port injection engines running full synthetic, you can safely go 8-10k miles of normal driving between changes, BUT a GDI engine experiences many times the amount of raw fuel washdown past the rings than a PI engine, and the particulate matter shed from the valve coking is a hard crystalline abrasive material VS the soft carbon of past, so add the water and sulfuric acid content and GDI engines quickly overwhelm the engine oils ability to protect. So 5k max is our recommendation.
Next, NEVER use a solvent based engine running cleaning on a GDI engine!!! Port injection and carbureted engines can be done safely, but the hard abrasive make up of the GDI deposits cause scouring (scratches) to the pistons and cylinder walls when the smaller particles are forced between them during this process. This also is responsible for a high incidence of catalytic converter failures from the amount of material hitting the catalyst and the shock of the solvent hitting the red hot catalyst.
Turbo engines these impact the hot side turbine wheel damaging the leading edges as well as it is expelled.
Always run a FULL synthetic with any GDI engine. The blends the dealer push on GDI engines leaves many times the amount of deposits when burned onto the valves as a full syn does, and just look at engine failures and timing chain issues with all GDI engines not running full synthetic.
Always use top tier fuel or a monthly in tank additive to keep injectors clean as even the smallest disruption in a GDI injectors creates droplets and burn issues as well as additional fuel wash down.
And, what is caught in a good effective designed can is far more than oil. In fact, a lab analysis puts the average drain as follows:
70% acidic water
23% un burnt fuel
7% oil and abrasive particulate matter
This is from a GDI drain. A port injection drain will have less fuel and water due to the intense cylinder pressures of a GDI engine and the fuel introduced at 2,000-3,000 PSI is what forces so much more raw fuel past the rings into the crankcase.
We have before and after dyno studies of GDI engines and manual valve cleanings, etc. if anyone wants to see, just ask.
Now, on a port injection engine, the main advantages of a good system is reduced KR form scrubbing the PCV vapors of disrupting oil and other contaminates and also keeping the oil cleaner longer by removing (evacuating) these contaminates before they have a chance to settle and mix with the oil. Remember, your oil filter only traps down to a particulate size of 15-10 microns, and 70% plus of internal wear comes from contaminates smaller then 10 microns, so the filter is not trapping these. And water and fuel and acid, once in the oil, much is there to stay aside from what can "flash off" with temps, but if not evacuated, it will re-condense when the engine cools.
We here at Elite Engineering USA not only do more research, engineering, and interaction with the industry as a whole than any other air/oil separating brand we know of. And that keeps us always at the leading edge of solutions and information to share with you, the consumer. A company of actual Engineers that make all systems here in the USA, and again, our "catchcan Challenge" is always open to prove there are no other more effective systems available than our latest designs.
