Toyota is well known for making dependable vehicles. However, no automaker is perfect. Several Toyota models equipped with a four-cylinder engine are prone to experiencing excessive oil consumption, especially ones built from 2006 to 2013. This problem is frequently referred to as “burning oil” by many people. If you don’t keep a close eye on the oil level, engine failure becomes a real possibility. Fortunately, there are some solutions to remedy the problem.
Switch to a Thicker Motor Oil
If you’re looking to reduce oil consumption without investing a lot of money, consider switching to high-viscosity motor oil. This is a particularly tempting option for drivers who own an older Toyota model with a lot of miles on the odometer. The thicker oil will be less likely to leak past the engine’s piston rings.
Unfortunately, there are a few downsides to using oils that have a higher viscosity. For starters, your gas mileage may not be as good. The engine must work harder to pump thicker oil, which ultimately results in wasted energy. Because high-viscosity motor oil doesn’t flow as easily, greater engine wear can also occur during cold startups.
Install New Oil Pistons and Piston Rings
According to many Toyota experts, the root cause of excessive oil consumption is often a defective piston assembly. Mechanics typically recommend replacing the oil pistons and piston rings. Installing upgraded versions of these parts should completely solve the problem for good. You’ll be able to travel long distances without worrying about the engine seizing because of low oil levels.
Remember, this is not a repair that should be done by a backyard mechanic. It’s a complex task that requires a large portion of the engine to be disassembled. You’ll need to take your car to an experienced auto shop.
Rebuild Your Engine or Install a New One
If your engine has been dealing with excessive oil consumption for quite some time, there’s a good chance other problems have started to develop. Stubborn deposits can form on the top of the pistons and exhaust valves. It’s virtually impossible to clean these deposits without taking apart the engine. Toyota owners who plan to keep their vehicle for the long haul may opt to have the engine rebuilt or install a new one.
There’s also the option of installing a used engine from a salvage yard in North Carolina. However, you should not overlook the potential risks. Only buy a used engine that has been professionally tested by a certified automotive technician. It’s also important that the engine comes with a legitimate warranty.
Can You Drive a Vehicle With Excessive Oil Consumption?
Ideally, you should have your Toyota inspected by a mechanic as soon as possible. If immediate repair isn’t an option, it’s probably okay to continue to drive the vehicle for a while. However, develop a habit of checking the oil level on a weekly basis. In just 1,200 miles, Toyota’s 2AZ-FE engines can consume more than a quart of motor oil. The last thing you want is for the engine to blow up.
