Engine oil OEM Honda or OEM Subaru

Take a quart of oil with, especially if you don't have reliable data on how much your engine burns. Check it occasionally and top off if needed.

Honda scooter oil & Castrol, tried and tested ko na. btw yung castrol ang ginagamit ko kapag summer na at sobrang init ng panahon then balik lang ulit sa honda engine oil once tapos na yung mainit na season

It'll be fine, my only argument against it is that you're probably paying too much for that quart. I've always used the Honda GN4 motor oil, buy a gallon for ~$30 when it's time for an oil change and have a little left to spare. Any dealership should carry this, Yamalube is also basically the same thing.

Yes, it is good advice. When a new engine is breaking in, there is a lot more wear metals. It's not uncommon to see metallic flakes or shimmer in the oil during your first oil change. Parts wear/bed in. That's why there is a break-in period on almost, if not all new cars.

I did my first oil change at 1k miles on my BRZ; I saw a lot of metal shavings come out of the oil. The oil also had a metallic shimmer to it. This is totally normal, but I want to get rid of all of that so it is not circulating around the engine post-break in period.

I would do 10k intervals in my Honda Fit but a majority of my driving in that car was highway. I'd also need to add a quart after 7000 miles because of consumption.

First gen Honda Insight, takes 2.6 quarts

23 hybrid accord, the dealership recommended 15k miles

6k is ideal.. so yeah 5k-6k. My 23 civic maintenance light came up between 5k-6k and i had like 15 % left on it

Did the break in oil change at 750 miles on my FL5 and was shocked at how bad the oil was. If you took a bright light to it there was lots of fine metallic debris in there.

I have a slow oil leak (something like a quart every 1,500 miles). Dealer quoted just under $3,000 for the fix when it was 17 years old with 110,000 miles. I'll just buy the occasional quart of oil.
