" I have a 2010 Acura TL with 3.7 liter V6 engine that I bought new. I have 115,600 km on the clock and my engine is picking up oil. I have to put at least 2 liters of oil between each oil change. Could adding an additive to decontaminate the engine help me lower oil consumption? "
First, you should know that this engine, which was present in the Acura RL, Acura MDX, Acura ZDX and Acura TL between 2007 and 2013 is known to be an engine that consumes oil. It is prone to a problem with carbon deposits on the piston rings, which causes the oil to not return to the sump and to be burnt by the engine.
After turning a deaf ear to complaints from many consumers who are dissatisfied – with good reason – that a vehicle paid for over $ 40,000 uses oil, Honda Canada finally decided to extend the warranty for this engine a few years ago. Be aware, however, that Honda never recognized the problem, and it was more with a "customer satisfaction" perspective that it was working to resolve it.
This extended warranty was valid for eight years or 200,000 km, from the date of the car's original purchase. Afterwards, the builder will refuse to pay for any repair whatsoever. At the time, letters were sent to all owners of vehicles equipped with such an engine.
However, if I count correctly, your car was bought new in 2010, which is at least 10 years, exceeding the scales issued by the manufacturer with its extended warranty. So unfortunately your car is no longer covered by any form of warranty, technically forcing you to pay out of pocket to correct the situation.
Whether a canned treatment can improve the situation and help "decontaminate" your engine, I don't think so. These are extremely stubborn carbon deposits, which require replacement of parts to eliminate the problem. Liquid treatment would not significantly change the situation. More serious mechanical repairs are needed, such as replacement of spark plugs, pistons and sealing rings.
Before you incur any expenses, there are a few steps to take. Turn to the Automobile Protection Association (APA) and the Consumer Protection Office (OPC) to argue that your car has low mileage and to get support in your efforts. This is the path to take since I unfortunately think that your chances of winning your case by pleading directly with Honda Canada are practically nil despite the low mileage of your vehicle, given the initial reluctance shown by the manufacturer to recognize the problem and correct it.
