Excessive oil consumption is a sign that the engine of your vehicle is not operating properly. An engine that is getting worn may burn smaller excesses of oil, but an engine that needs the addition of an extra quart of oil will most likely need to be fixed. Worn piston rings, damaged gaskets, car problems with the PCV system, and damaged seals can all be possible causes for oil loss from the engine of your vehicle. If your vehicle requires larger amounts of extra oil, in between your regular oil replacements have the problem inspected and repaired.
Step 1 – Inspecting for Excess Oil Consumption with No Exhaust Smoke
If your vehicle is using extra oil but shows no indication of smoke coming from the exhaust system, you could have an issue with your PCV system. The solution to this problem needs replacing the valve. This situation can also happen if the engine is experiencing mechanical problems. You will need to check the compression to know the state of your engine. Excess oil consumption without smoke can equally be caused by worn or damaged gaskets or valve seals. The gaskets and seals will need to be changed in order to solve the problem.
Step 2 – Checking for Excess Oil Consumption with Brown and Foamy Discolored Coolant
If your vehicle is using extra oil and the coolant has become foamy and brown, and there are no indications of leakage, the head gasket in your vehicle may have blown. It will need to be changed. Discolored and foamy coolant can also show a cracked cylinder head. It will also need to be repaired or changed. You could also have a leak in your oil-to-water cooler and it will need to be changed.
Step 3 – Checking for Excess Oil That Produces Oil Puddles Under the Car
If your vehicle is burning extra oil and you see droplets under your parked vehicle, you most likely have an oil leak. There may or may not be the appearance of smoke and the smell of burning oil. Be sure the engine oil level is correct. This issue could be caused by improperly operating PCV system. The PCV valve will need a replacement. The gaskets and seals could have become damaged due to wear. They will need to be changed. Your oil filter could also be loose. You will need to tighten the fittings, replace the filter, or change the drain plug.
Step 4 – Inspecting for Excess Oil with the Appearance of Smoke from the Exhaust
A vehicle that is using excess oil and that has smoke coming from the exhaust may equally show less engine power. These issue could be caused by a problem with the PCV system. If so, the PCV valve will require replacement. The engine may also be experiencing mechanical issues. You will need to check the compression to know the state of your engine. These signs could be an indication that your piston rings are worn. You may have to replace them. The valve seals could also be worn and need replacement.
