Honda has been manufacturing the 1.5 turbo engine, a compact 4-cylinder engine, since 2016 up till the present. In their series of engines, this one is the entry-level model. All Honda base models come with these four-cylinder engines. but largely in smaller vehicles that don’t need much power to operate. In a moment, we’ll get into more detail on the 1.5’s uses, but first, let’s talk about its specifications.
As we previously stated, the 1.5 is a four-cylinder engine with a tiny turbocharger. The turbocharger helps this 1.5 to generate 174 horsepower. While the Civic Si’s Civic Si-tuned version of this engine, which has a larger boost, produces 205 horsepower, which is outstanding for an inline-four engine.
This engine is made entirely of aluminum. This indicates that aluminum was used to make both the head and the block.
The engine has two overhead cams, just like the majority of Honda engines. The turbocharger that this engine uses makes a difference. The 1.5 is the ideal engine if you’re looking for a compact and fuel-efficient engine on the market right now because the turbocharger is quite modest and incorporates some of Honda’s inventiveness.
As previously stated, the engine generates 162 to 192 pound. ft. of torque and 174 to 205 horsepower. If you want an engine that is producing a lot of power, the more potent variants are fairly punchy and are the way to go.
But what issues are there with the 1.5-turbo Honda engine? Later on in the article, we will learn more about this. Let’s first examine the operation of a turbo engine.

Is the 1.5 La Honda engine a decent one?
The Honda 1.5 Turbo is a great engine all things considered. While offering plenty of power and torque for the majority of drivers and conditions, it is compact and economical. However, the engine makes use of some technology that is somewhat newer than that used in Honda engines. Direct injection and turbos add several extra components and possible problems. Notably, direct injection results in carbon buildup that eventually requires cleaning.
It also takes a while for the engine to warm up because the Honda 1.5T is so efficient. This can lead to problems since too much fuel will contaminate the engine oil. Fortunately, Honda provided a longer warranty and some software updates. However, there may be significant long-term reliability and longevity issues with fuel dilution on the 1.5 Turbo.
Other than that, the Honda 1.5 Turbo doesn’t have many typical issues. Spark plugs are a rather unimportant component overall. However, they draw attention to the fact that maintaining turbo engines can be a little more difficult. If you take care of the 1.5T, it should give you steady service for a very long time.

Which Honda engine is the most trustworthy?
But the decision for the top slot on the list was comparatively simple. Even while the high RPM power and output per liter of the B and K-series four-cylinder engines are remarkable, there is one Honda engine that is marginally superior.
That would be the F20C, which was created for the Honda S2000 roadster with rear-drive. The 2.0L F20C, which was packed with racing DNA and produced an astounding 240 horsepower, ranks among the highest specific output production engines of all time. The S2000 became an instant classic as a result.
Of course, the bigger F22C, which debuted in the AP2 model a few years later and had enhanced low-end torque at a somewhat lower redline, is in some ways the superior engine overall.
However, the original F20C is our choice for the best of the best when it comes to sheer engineering brilliance.
Does Honda 1.5 Turbo have VTEC?
Turbo engines are typically thought of as having “great power, low fuel economy,” however Honda’s VTEC TURBO engine achieves fuel efficiency without sacrificing the pleasure and quality of the ride.
The 1.5L VTEC TURBO maintains all the advantages of a compact engine in terms of fuel efficiency while adding a turbocharger, direct injection, and variable valve timing. Because of this, it generates power that feels smooth from low to high revs, outperforming the torque of a 2.4L engine. Acceleration remains thrilling as a result on all types of roads, from city driving to motorways and even mountainous climbs.
How long will a 1.5 turbo Honda engine last?
With the exception of those with problems with oil dilution, Honda’s turbocharged engines are typically rather robust. With routine maintenance and repairs, they can go up to 300,000 miles without experiencing any major breakdowns.
Which Honda engines have issues with oil dilution?
One of Honda’s best-selling car models is the CR-V, which also held the top spot in terms of popularity for a number of years. However, due to an alleged flaw in its Earth Dreams 1.5L direct injection engines, recent model year Honda CR-V automobiles reportedly experience oil dilution.
A class action complaint claims that Honda’s 1.5L Earth Dreams engines have gasoline-diluting engine oil, which can lead to issues including stalling and power loss while driving.
Owners of 2019–2021 Honda CR-V vehicles filed complaints with the National Highway Traffic Safety Administration alleging engine damage, stalling, fuel mixing with oil, and stalling. Below, you may see a list of some of these issues, along with earlier complaints from Honda Accord and Honda Civic customers.
How durable are turbocharged engines?
Despite the fact that certain turbocharged engines are dependable, turbo engines frequently have additional issues. A normally aspirated (non-turbo) engine has fewer parts than a turbocharged engine. These include an intercooler, boost control system, vacuum pump, exhaust wastegate configuration, and a more intricate crankcase ventilation system (PCV). Failure of the turbocharger itself is not unusual. More things can go wrong the more parts there are.
Higher combustion chamber pressure causes higher crankcase pressure when the cylinder walls and piston rings deteriorate with increased mileage. This may lead to oil leaks that appear in numerous locations and are challenging to rectify.
Having said that, many turbo engines have a lengthy lifespan. Consider the Mark IV Volkswagen Golf / Jetta’s turbodiesel (from the early 2000s). With proper maintenance, many of them are operating well into 200K miles. Learn more about engine maintenance.
Does Honda still have an issue with oil dilution?
Currently under investigation by Migliaccio & Rathod LLP are the 2019–2022 Honda CR-V, Civic, Accord, and several other vehicles.
The 2019–2022 Honda CR–V, Civic, Accord, and specific Acura models equipped with the 1.5L turbocharged engine are under investigation by Migliaccio & Rathod LLP for possible fuel dilution problems. Particularly, owners complain that gasoline and engine oil mix, causing the oil level to rise and the vehicle’s ability to lubricate to decline. Owners claim that oil diluting still occurs despite a software update that was intended to fix the problem. For some, the car’s interior smells like gasoline, while for others, the acceleration is lost, and for yet others, the steering is affected. Because owners have reported feeling loss of acceleration while driving, this problem puts Honda and Acura owners at risk for both premature engine wear and accidents. Owners claim that while Honda dealerships admitted this was a problem with the 2017–2018 model years, they thought it had been resolved for the model years 2019 and onward. In order to remedy the fuel dilution issue, Honda has not issued a recall.
