It has been said that Honda makes the "best engines in the world." I believe that the 2.4L ivtec engine was one of those engines being described.

After updating sensors on my 2009 Honda CR-V EX AWD, 215,000, I'm once again getting 30 MPG. In the pics. below, this test over 20 U.S. miles on a relatively flat road and low ambient temperature, not quite freezing, and speed limit of 55 MPH displays the results.

Do you agree? Are you happy with the Honda 1.5L Turbocharged engine?

I 100% agree being a 2.4 liter K engine owner. My block revision is the K24Z6 specific to the 2010-12 CR-V, and haven't had much problems other than the low friction piston rings causing some increased oil consumption. With maintenance, I constantly get 26-29 mpg easily on the highway depending on terrain and air temperature. Which sensors did you update as might do the same on my V once it reaches 200k.

Genuine Honda PCV valve, Thermo Bypass Solenoid Air valve 36281-RTA-003, removed and inspected the MAP sensor, cleaned the MAF sensor with Genuine Honda MAF cleaner. All new Honda filters and fluids, and I'm about to replace the coolant for the third time. I'll also be removing my winter wheels soon.

My sister and her husband both have CR-Vs. His is a 2016 with the 2.4, and hers is a '23 model with the turbo. They both have said they like the 2.4 better, but no real complaints about the turbo (yet). I would bet any amount of money the 2.4 would outlast the turbo, but my sister never keeps her vehicles long enough for engines to go bad. Me on the other hand, I currently have an '04 Corolla with 450K miles, so I want one with an engine that will last, which is why I'm looking for a CR-V with a 2.4...
