Honda models affected by the oil dilution issue include: the new CR-V, 10th-generation Civic, new Jade, URV, and Avancier. Taking the Honda Avancier 2020 240TURBO 2WD Elite Edition as an example, its body dimensions are: length 4858mm, width 1942mm, height 1670mm, with a wheelbase of 2820mm, trunk capacity of 510L, and a curb weight of 1708kg. The Honda Avancier 2020 240TURBO 2WD Elite Edition is equipped with a 1.5L 4-cylinder turbocharged engine, delivering a maximum horsepower of 193PS, maximum power of 142kW at 5600rpm, paired with a continuously variable transmission.

As an owner of the Honda CR-V, I have personally experienced the oil dilution issue. The 2017 to 2018 Honda CR-V and Civic models were the most affected, as they were equipped with the 1.5-liter turbocharged engine. In the Chinese market, similar issues were also reported with the UR-V and Inspire, but the CR-V and Civic were the focus of the recall. The cause of oil dilution was gasoline mixing into the oil pan during cold starts, leading to increased oil levels, which could potentially shorten engine life or cause malfunctions. During winter, I frequently checked the oil dipstick and became concerned whenever I noticed the oil level rising. After Honda's recall, they provided software updates and part replacements, which improved the situation. I recommend other owners to regularly monitor their oil levels and not wait until major problems arise to take action. If you own an affected model, promptly contact a 4S dealership or professional repair shop to ensure safe driving is not compromised. Overall, the CR-V and Civic accounted for the majority of oil dilution cases, especially in early production batches.

From a technical perspective, the Honda oil dilution issue involves models such as the CR-V, Civic, UR-V, and Inspire, particularly focusing on the 2017-2018 1.5T engine variants. The problem stems from the engine injection design, which causes gasoline to leak into the engine oil during cold starts, increasing oil volume and diluting viscosity. I've studied recall data—in China, Honda conducted large-scale upgrades for the CR-V and Civic, covering nearly a million vehicles. Other models with similar engines, like certain Accord variants, also had sporadic reports, but the CR-V and Civic were the main focus. The repair solutions included ECU software upgrades and oil circuit component replacements, which proved effective. As an automotive enthusiast, I've noted that this issue not only reduces fuel efficiency but also increases long-term maintenance costs. Owners have shared their experiences on forums, helping identify high-risk vehicles. If you own one of these model years, regular maintenance is advisable to prevent potential problems.

In the Honda oil dilution incident, the main models affected were the CR-V and Civic, particularly the 2017-2018 models. This stemmed from a design flaw in the 1.5-liter turbocharged engine, where fuel dilution of the engine oil could impair engine performance. I am particularly concerned about safety, as increased oil levels may lead to engine overheating or sudden stalling, raising the risk of accidents. In daily driving, CR-V and Civic owners reported the most cases, with a few instances also noted in the UR-V and Inspire. Honda addressed some issues through recalls, but owners still need to regularly check their oil levels. I believe safety comes first, and early detection can prevent major problems. If any abnormalities are noticed, drivers should stop immediately and seek professional help, never ignoring the engine warning light.
