Engine oil OEM Honda or ROWE

I found out that most of it came from the valve lifters. So I began using Rowe 10W40 engine oil. That helped a lot.

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.

The road spec oils are excellent for daily driving and trackdays. Smoother engine, better engine efficiency, no oil consumption.

ITS A LOT THICK! than other brands of the same weight.. but when you abuse the vehicle it gets smooth like butter. I like them if I plan to aggressively dune bash.

I use Rowe as well and it's fantastic. No complains so far

I use rowe on all my cars, amazing oil but it’s more expensive

I've used Rowe, no complaints

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

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.
