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.

Does the 2022 Honda CRV 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.

Has Honda addressed issues with turbo engines?
Honda has always been associated with dependability and high-quality construction. In fact, Honda cars are so good that they regularly appear on top rankings for many kinds of car categories.
Unfortunately, Honda’s reputation has been severely harmed by the engines produced in recent years, particularly the small, direct-injection turbocharged engines.
The 2019 models were expected to remedy the Honda Turbo Engine issues, but the flaws have not been totally fixed. Honda cars from 2020 and 2021 could still experience turbo problems, although the likelihood is now lower.
Do Honda Accords have issues with oil dilution?
A class action complaint claims that Honda’s Earth Dream engine flaws lead to oil dilution, engine stalling, early wear and tear, and engine failure in 2018–2021 Honda Accord automobiles.
Honda Accord 1.5 Turbo Engine Problems
One of the issues with the Honda 1.5 turbo engine is that it cannot heat up properly while idling. To put it another way, it takes longer for the engine to warm up sufficiently, which can be an issue for people who live in colder climates. Occasionally, it won’t generate enough heat until you begin moving. Condensation and too much gasoline vapor production are both possible effects of cold engines. The engine oil might easily become diluted by all of that extra fuel. Its direct-injection system also has a drawback in that the intake valves accumulate carbon. When coupled with that chilly engine, this is even worse.
Honda Civic 1.5 Turbo Engine Problems
The Civic experiences the same problems as the larger Accord, which has a higher tuned 1.5 turbo engine. The engine experiences fuel-oil dilution, which frequently happens in colder climes. The 1.5 turbo engine takes way too long to warm up because it is so efficient. When this happens, extra fuel vapors are not burnt, and they adhere to the cylinder walls. Following that, the oil picks up on it and dilutes it. Then, two additional significant problems are added to the oil dilution problem. First off, there is a significant amount of carbon buildup on the intake ports. Additionally, the spark plugs might easily become fouled.
Honda 1.5 Turbo Engine Problems
The good news is that by 2021 and 2022, most issues with the Honda 1.5 turbo engine had been resolved. The main problem with the 1.5 turbo engines was oil dilution, which on its own led to other problems. This is mostly because the 1.5 turbo engine takes a while to warm up, especially in cooler weather. Honda only made a minor adjustment to the ECU to fix this. As a result, the 1.5 turbo engine could start out slightly richer. Additionally, Honda helped the engine warm up by directing some of the heat from the passenger compartment there.
How Long Do Hondas Last
One of the world’s toughest and most resilient automobiles is the Honda. They should easily be able to reliably go between 200,000 and 300,000 miles. This could be increased even more with careful maintenance and servicing. In other situations, owners have relied on their Hondas for up to 20 years with little problems compared to the majority of other vehicles.
Did Honda Fix The Oil Dilution Problem For 2021
Sadly, this problem still exists in 2021 despite a software modification to assist Honda’s engines heat up more (which is the primary source of oil dilution). In particular, oil dilution still affects the 1.5 turbocharged Earth Dreams engines in 2021 and 2022. Owners may only prevent severe dilution by changing their motor oil more frequently in the first place. Some owners advise changing the oil as soon as every 3,000 miles.
Which Honda models are prone to oil dilution?
My oil has twice been found to have more gas than 5%, according to research. The oil dilution issue that Honda CR-Vs (model years 2017 and 2018) have experienced worries me. The 1.5 liter direct injection Honda CR-V engines have experienced premature engine damage, and more significantly, loss of power or stalling on the highway.
Which Hondas are equipped with the Earth Dreams engine?
The Honda Earth Dreams V6 is a 3.5L engine with i-VTEC for increased efficiency and 278 horsepower for a little oomph that can be found in various Honda Accords. Utilizing its variable cylinder management, the V6 may run on three or six cylinders, ensuring that drivers never waste gasoline.
Which Honda engine, the 2.4 or 1.5 turbo, is superior?
Although the 2.4L inline-four engine is marginally more efficient and accelerates more quickly, the 1.5L turbo engine has reliability issues that have damaged Honda’s image.
In contrast, the 2.4L inline-four is a tried-and-true engine with a superb dependability record that, with routine maintenance, should last well over 100,000 miles. The 2.4L is the greatest option despite being only offered in the less expensive LX model due to its dependability and affordable running expenses.
Honda 1.5 liter turbos are they trustworthy?
Is the 1.5T Honda engine dependable? Yes, the engine is often rather dependable. Regarding dependability, we’ll give the Honda 1.5 Turbo above ordinary feedback. Time will tell how they perform over the long term because the engine is still relatively new. There are a few typical issues with the 1.5T engine, but they aren’t anything too serious. However, excessive oil dilution should be avoided since it can shorten the lifespan of the 1.5 Turbo. Apart from that, the Honda 1.5T is a strong, dependable engine.
However, for those unfamiliar with turbo engines, maintenance may be a little more difficult. Spark plugs and ignition coils, for example, are subject to more wear and tear while operating a turbo. The engine also receives a lot of additional hardware that can malfunction.
However, the Honda 1.5 Turbo shouldn’t see any problems going over 200,000 miles with regular maintenance. Shortening the time between oil changes is a smart suggestion if you’re experiencing fuel dilution. Maintain routine maintenance and keep an eye out for issues when they arise. If you follow these steps, you’ll probably have a fantastic, dependable experience with the 1.5T.

Does the Honda CR-V from 2021 have an engine issue?
The SUV Honda CR-V from 2021 has drawn a lot of interest. Even though the company says its vehicles are “designed to drive you farther,” most media coverage has not been positive. In truth, this model has many unhappy owners because of problems with the electrical system, engine, and frame.
How durable are four-cylinder turbo 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.
What level of oil dilution is excessive?
- After 100 hours of operation, change the engine oil and resample to ensure that the abnormality identified by the used oil analysis has been resolved. As a result of myLab’s large sample library, you can trend against a known segment that exhibits comparable anomalies in contrast to others under the same operating and environmental conditions. Then, a human element comprised of expertise and training can be added on top of cutting-edge algorithms, artificial intelligence, and machine learning.
- The source of the fuel dilution must be identified and fixed if it is greater than 4%. When gasoline dilution exceeds 4%, the engine oil must also be replaced, and it’s important to keep an eye on trends in successive tests.
- To make sure the transfer pump weep hole stays open, it should be checked frequently and cleaned if necessary.
- Significantly leaking injectors should be replaced and adjusted (not just seeping).
- Install valve covers, reconnect the fuel lines, and start the engine to check for leaks in the oil or fuel.
- To help “distill off the fuel and to help rid the oil of some of the condensations built up from running an engine “cold,” an engine that is frequently idled should be brought to full load and run at operating temperature.
- Conduct a dye check for leaking fuel injectors in accordance with OEM specifications if fuel dilution persists to rise. Examine each unit injector near the rack bar area with a black light. A distinct streak (noticeable difference) of dyed gasoline will be visible from the rack bar region if an injector is leaking. During this test, ALL injectors will bleed and perhaps display a little amount of colour. A small amount of seepage is regarded as NORMAL.
