Just reached 50,000 with my 2017 Honda CRV. Couple of updates:
Hondata Reflash
I did a Hondata reflash at 17K miles - no issues so far. Since the reflash the car is quicker and gas millage has been 30 to 34 MPG measured at the tank.
Tires
Replaced the stock Bridgestone’s with Michelin Premier A/S tires at 30K miles. I could not stand the noise level. The Bridgestone’s probably had another 15K of tread life. The Michelin Premier A/S are much much quieter, but they are one of the most expensive tires you can buy for the CRV.
Engine Oil
I did the 48K service myself and used Amsoil engine oil. First the engine is notably quieter with the Amsoil versus the stock Honda oil.
Second I found that he dealer was overfilling the crankcase - The oil level was always where the orange plastic joined the metal part of the dipstick – not at the high level oil mark. At first, I thought I had gas in the oil – it turned out that it was a overfilled crankcase.
Transmission Oil
I also changed the transmission oil early with Amsoil at the 48K miles. The transmission was making a whining noise. Now it is quiet like new. The transmission also made the same noise just before the 30K transmission oil change.
Intake Valves Cleaned
I also cleaned the intake valves at the 48K mile service with CRC Intake valve cleaner. Direct injection cars carbon over the intake valves which can cause stalling, rough idle, and, poor gas millage in higher millage cars. I did notice a smoother idle and a slight increase in gas mileage (about 1 MPG), but I also changed to Amsoil engine oil and changed the air filter – so I am not sure if the intake valve cleaner caused the difference.
