I know this has been discussed before, but I can't seem to find a definitive answer. I have a 2018 Fit (6M). I called the dealership where I bought the car to ask about whether Honda still uses break-in oil like they did in years past, and the "service technician" had no idea what I was talking about. I swear these people are simply there to try to sell use services we don't need.

Neither the Honda website nor my owner's manual mentions special factory-fill oil (like the website used to do), so I am assuming that the car comes from the factory with regular motor oil in it.

Does anybody know for certain?

 

I doubt that any Honda in the past 20+ years used a special break in oil. At most there may be an assembly lube on the camshaft(s) that may help with break in.

We did our first oil change at 500 miles with conventional oil, second at 1500 with semi-synthetic, third at 3000 with full synthetic and have since changed every 5,000 miles with full synthetic. Way overkill, but no oil loss/burning at 190,000 miles.

Everyone can do whatever they want with their own car, but I would never run oil more than 5,000 miles. Have sent in numerous samples to Blackstone labs from numerous cars through the years. Every car is different. The Fit being a fairly low hp per liter, low rpm, and naturally aspirated does not wear oil out like some can, but I still change at 5k. Oil isn't very expensive.

 

BTW, that mechanic maybe wasn't that dumb. Break in oil may have not been used since he was born in OEM manufacturing.

Actual break in oil is not meant to be run more than a few hundred miles or a few hours. It is very high in additives and is only supposed to be run for a very short time.

Hence, why there's zero chance of Honda running a break in oil. That was from back when your first oil change had to be at 500 miles or less.

You still see this in some power equipment like generators, lawn mowers, etc. They will call for a first oil change at 50 or less hours.

 

My 2010 Fit came with break-in oil. Honda said not to change it early.


My 2016 Fit owner's manual says nothing about break-in oil.

 

Can you point to where it says in the 2010 manual to not change it early? I don't see it in my 2008 and can't find it in the 2010 manual online. Here's a link to the one I'm looking at. Looking in the oil section, but maybe it's elsewhere?

Edit - found it. Page 198. Doesn't say there's break in oil, but it says to not change until the scheduled maintenance time.

 

Looking at a newer manual, it appears they have removed the entire break in section. Maybe decided it was too controversial with so many different schools of thought even from OEM engineers.
