On my wife’s 2016 Exl i chnaged FF at around 4K. After that 4-5K OCI with different 0w20 - good UOA on all of them with really no difference. Not using any oil and piston slap on cold is still there
Did you encounter piston slap from the start? I have not noticed any with ours.
What does the Honda owner's manual say on this subject? Any particular info w/r to break-in and the factory fill? I would just do what it calls for. 7500 is such a good number to go with b/c it works with tire rotations.
Good question. I will check tonight as I have really not thought about it too much since it is new.
Honda says leave it for full OCI or down to 15% on the MM.
More importantly is to check it periodically for oil consumption during first OCI. Then head over to Piloteers and read about disabling the VCM
So far the oil level has remained at the full mark.
Honda does use a “break in” oil and recommends the factory-fill oil remain in the engine until the first scheduled maintenance interval to ensure proper break in. Now there will be a lot of opinions about changing the “break in” oil early but I say follow what Honda recommends. I have owned several Hondas and currently have the Accord with the same 3.5 V6. I kept the break in oil until the MM told me it was time to change and use the MM to let me know when an oil change is due. I have done oil analysis and the oil still shows good and could have went past what the MM recommends. There were VCM issues in the past with the 3.5 but that has been resolved with current V6s. I say use the free oil changes but make sure they use 0W20 synthetic like the Castrol and they don’t try to sneak in a 5W20 dino or blend. Also, make sure you use top tier gas. When I say top tier gas, I do not mean octane rating. Top tier gas is gas that has additional detergents that exceeds EPA recommendations. There is a website that you can find certified gas stations that sell top tier gas. Exxon and Shell are two popular gas stations that sell top tier gas. Using top tier gas really helps keeping the engine clean, especially with Honda’s VCM.
Do you recall the mileage when the MM got to 15%? I have instructed the wife to use Exxon/Mobil, Shell, or BP as they are all top tier gas stations in our area. We have run a couple tanks of Kroger gas through it. That was due to having fuel points worth $1 off per gallon. Getting 35 gallons of gas at $1.32 or so per gallon is worth it once a month. I have read that some Kroger gas is top tier and others stations it is not....depends on who the supplier is.
