This will help with a cleaner-burning engine and should result in optimal fuel economy.Ī Con with putting an oil catch can on is that you are now no longer SMOG compliant in the state of California.
This is one way that you can keep oil from building up inside your intake manifold.Ī pro for having a catch can be to separate your oil and prevent it from going back into the engine. Periodically the car owner will open the can and dump out the excess into a suitable waste container. They use the catch can to holds the excess oil. On Prius, most do not route the oil back to the pan. Then the separated oil is allowed to return back to the pan. The genius behind the oil catch can is it separates oil and air from the PCV system. The same thing happens with the oil getting trapped into the gasses and getting circulated back. Those devices cram more air into the engine and can cause more blowby. Some Prius owners have reported that adding an oil catch can have helped them keep unwanted oil out of the combustion chamber.Īn oil catch can typically be installed on vehicles with forced induction, meaning a turbo or blower. How Can I Help With Oil Consumption On My Prius? The issue is that those gasses are carrying bits of oil which end up getting dropped into the intake manifold and causing driveability problems. As the gasses move and carry the oil with it, those gases get routed back into the intake manifold for re-burning, helping to lower emissions, among other things. The oil now trapped gets re-rerouted back through the positive crankcase ventilation system or PCV. This action is called "blowby," and what can happen is the excess pressure that goes into the oil pan area called the crankcase will pick up tiny bits of engine oil. As the engine wears, more exhaust gasses pass by the piston rings. Prius owners with a 1.8L engine have an efficient engine, but it comes at a cost. Sometimes just doing a treatment will help, but other times it is not enough. In a previous article, I spoke of a product by BG that can help with oil consumption. Dealing with it once it does happen is where you need to place your focus. Whatever your case may be, know that it can and does occur over time to your car. Other reasons it can happen are from worn-out piston rings or even a plugged PCV valve. Especially with Prius, it can be caused due to excessive carbon build-up in the piston ring lands. Oil consumption can happen for a few different reasons. This article will talk about what causes oil consumption and what you can do about it. The Prius with a 1.8L engine has become a notorious "oil guzzler." It is a cause of some issues for Prius owners. If you are like the thousands of other Toyota Prius owners on the road with an oil control problem, you may have heard there is a solution.
