Engine oil OEM Honda or OEM Subaru

Só uso óleo Honda original do meu, e mineral. Depois que li o manual e vi um aviso gigantesco falando pra usar apenas ele, nunca mais cogitei trocar kkkkk

Oil being dark is a good indicator that you have to do an oil change. However, you shouldn't wait until it changes color to do it. Clear oil doesn't necessarily mean you can keep going.

It is well established that boxer engines want their oil changed and I do not think for a second that a visual inspection is valid for determining if it is time. Highly, **highly** recommend you change the oil per the manual without hesitation and regardless of what it looks like.

I have a Fit 2019 and switching from 5w30 to 0w20 improved my mileage from 650 km/tank to 800 km/tank.

I would also make sure that every time you fill up the gas you check the oil dipstick and if it’s a little low top off the oil. In fact, I think this is probably crucial to owning an older Subaru like mine mine has 300 K.

I second those saying bring a spare quart of oil. I wouldn't be too worried about taking my 2012 Outback at 170K miles on such a trip...but would agree check the oil every 1000 miles or every morning (depending how far you go in a day) just to make sure it isn't getting low.

Check all your fluids ASAP. If any are low, top off as per the manual and monitor closely before you leave to make sure it's not leaking or consuming anything. Definitely bring extra oil, 1 or 2 quarts would be pleanty, and some paper towels and rubber gloves help too.

Should be fine, but CHECK THE OIL FREQUENTLY. This series of engines is notorious for oil consumption problems, which may not appear at all when doing short trips, but suddenly it's drinking 1qt or more per 1000 miles on the highway.

Before I boosted mine, I would do 5K all the time. Now it's close to 4k, anything over that and feels like shit driving it.

I avoid the 5 minute drive-thru places. One of them wanted over $100 for full synthetic on my Subaru Forester. Not worth the 5 minutes.
