Oil Additives vs Oil Catch Cans

Posted by on 7/3/2019
What do motor oil additives do?
Auto parts stores are jam-packed with aftermarket motor oil additives and oil treatments that promise a great number of advantages and benefits. These claims include:

Increased fuel economy
Reduced friction
Maximum horsepower
Improved engine cleanliness

To provide this additional performance, aftermarket motor oil additives use chemical components to boost the motor oil formula. Some aftermarket motor oil additive products have added ingredients like Teflon, molybdenum or graphite. Some have used chlorine, which can be highly corrosive when mixed with water.

Oil Catch Cans and Vehicle Warranties

Posted by on 7/2/2019
We often get questions about if installing an oil catch can will affect the current warranties on that vehicle.

First, let's get what an oil catch can does with your vehicle. As most of us know an oil catch can filers out and catches carbon, oil, acid, and water from entering your engine. These contaminants will over time cause your engine to lose performance and gas mileage from engine coking from blow-by. Blow-by is not something new with modern engines. It has always been around. Back in the day when we had no concept of protecting the environment the "dirty" air produced by the vehicle's engine was in released into the air. All that nasty oil residue was allowed to drip out of the engine onto the roads. With the event of emission laws, the auto manufactures idea was to have all those contaminants recycled back into the engine. This solved the emission problem but made a different type of problem. Since then Auto Manufactures have changed their engines quite a bit to get better gas mileage and performance but the truth of the matter is a gas engine is going to produce blow-by. It is the nature of the beast and carbon, oil, acid, and water will always be a by-product of GDI Engines.  

Why Auto Manufactures do not include Oil Catch Can?

Any modified performance car that you see will have some sort of oil catch can on them. Oil Catch cans are placed by the car owners themselves which begs the question why do the car manufacturers choose not to place an oil catch can in the vehicles. Any GDI Engines benefits greatly from Oil Catch Can let alone a performance vehicle. 

What are the benefits or a Dual Valve Oil Catch Can vs a Single Valve?

Posted by on 12/18/2018 to News
There are many Oil catch cans out there on the market to choose from and a substantial price difference. The statement you get what you pay for does hit the mark when it comes to PCV Oil Catch Cans. Many Oil Catch Cans who are on the lower end of the price bracket are single port cans. This means they have 1 "in" valve or port and 1 "out" valve. With all PCV Oil Catch Cans, the "in" port is always connected to the Positive Crankcase Valve. This is where the dirty air exits the engine and goes into the intake manifold to recirculate back into the engine. Back in the day before air pollution control, these gases were let out into the atmosphere. Routinely, there was a tube that pointed down and that allowed the oily residue to drip out. That is why there used to be a lot of oil on the roads.

Keeping Your Oil Catch Can from Freezing in the Winter Months

Posted by McNally Electronics on 12/18/2018 to News
We often get inquiries on how to keep an Oil Catch Can from freezing. The truth of the matter is there are some cold environments that a can is going to freeze. The contaminants that are filtered out of an oil catch can consist of Oil, Carbon, Acid and Water. Even though most of those elements have a freezing point well below 32 degrees Fahrenheit (0 degrees Celcius) the water component will freeze. Once these elements are caught in the catch can and sit overnight they will start to separate.  If you open the release valve and the can does not empty due to it is frozen you may be able to take a paperclip, a wire, or something of the sort and insert into the bottom valve. This pokes a hole in the "frozen water" portion of the contaminants and allows the can to drain.

What are PCV Oil Catch Cans and Why Do Direct Injection Engines Need One

Posted by on 4/17/2017 to News

Purpose of your Stock PCV System:

The PCV (Positive Crankcase Ventilation) system is designed to regulate and remove fumes from the engine crankcase, and to alleviate crankcase pressure which could cause oil leaks or seal damage. It’s a way for gases to escape in a controlled manner from the crankcase of an internal combustion engine.

During normal operation of an internal combustion engine, there’s a compressed air and fuel mixture inside the combustion chamber that is ignited and as a result, forces the piston down. A small amount of that ignited mixture leaks past the piston rings and ends up in the crankcase. This leakage is often referred to as “blow-by” (leakage past the piston rings), as well as oil mist.

Purpose of the Clean Side Separators

Posted by on 12/9/2016 to News

Here at McNally we offer two types of Clean Side Separators. Our regular CSS is made of heat resistant plastic and our Premium CSS is made of billet 6061 T6 aircraft grade aluminum.

The Clean Side Separators are specially designed for use with Catch Cans to trap and remove oil vapors from the clean side of the oil separating system while retaining 100% MAF metered air.

  • Engine Runs Cooler
  • Increases Fuel Efficiency

What Oil Catch Can Should I Purchase?

Posted by on 8/8/2016 to News
We hear this question all the time. What type of Oil Catch Can goes with my vehicle? You can imagine with all the different types of engines and performance components that can be installed, how confusing it can seem to be. It really isn’t.
Each vehicle varies with the amount of contaminates that is filtered out. Our Regular Oil Catch Can is a total height of 10 inches with a 3 inch diameter and our Monster Oil Catch Can is 10 inches with a 4 inch diameter (with stems attached). While choosing what Rx Oil Catch Can by McNally to install in your vehicle there are some things that should be aware of. How many engine cylinders do I have and does your engine have a turbo system installed?

Catch Can VS Catch Can – In the Wild, Wild, West!

Posted by on 8/8/2016 to News
There are many choices out there in the market place for Catch Cans. You seem to see them everywhere now. Just a simple search on Ebay could only confuse you more if you were already wondering what type of Oil Catch Can to get for you vehicle.
Oil Catch Cans have been around for a while now. With the event of Direct Injection Engines or Port Injection Engines that promise higher fuel efficiency consumers of these vehicles are finding out that that promise will soon go away. It doesn’t take long for the blow-by produced from these type of engines to hinder performance and horsepower. To combat this car owners should have an Oil Catch Can installed in their vehicle. Now comes the problem… Which One? There are many to choose from.

Intake Valve Deposits in Gasoline Direct Injection Engines

Posted by on 3/15/2016 to News
Gasoline Direct Injection (GDI) is used on a variety of late model engines: Audi, BMW, GM, Ford, Hyundai, Lexus, Mazda, MINI, Nissan, Porsche, VW and others. A GDI sprays fuel directly into the combustion chamber under high pressure, rather than spraying fuel under low pressure into the intake ports in the cylinder head. GDI increases fuel economy and power 15 to 25 percent, but there is a downside that is now becoming apparent as these engines with accumulate miles. The problem is carbon deposits are building up on the inlet side (top) of the intake valves. The deposits can create turbulence and can restrict airflow into the cylinders causing performance and drivability problems (hesitation, stumbling, misfiring, and even hard starting). The thicker the carbon deposit buildup on the valves, the worse the drivability problems.
