Engine oil Castrol or OEM Honda

I've had good luck with Castrol for several years in two WRXs.

If your interval is 30,000km / 20k mi (2Y) then you should use the higher spec VW 503 / 504 (left page) if you have the 15,000km / 10k mi (1Y) interval then you can use the lower grade VW 501 / 502 oil on the right page.

I always use Castrol, good quality oil won't hurt the engine and is just slightly more expensive than off-brands.

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.

any oil that meets the LL-01 standard will do, buy whatever is on sale. Castrol Edge Euro 5w30 is fine, Mobil 1 euro synthetic, whatever.

My conclusion was to use the best Castrol in the gold bottle. Of course, YOU must use the specification of weight recommended by the owners manual for the temperature range you expect to be operating in.

The gallon of Castrol is the same whether you buy it at CT or Napa.

Personally I always run Castrol and it's done me well, even in older cars that had been a bit battered.

I’m stupid and like Castrol. Is it any better than the Walmart 5w30 synthetic? No. It just usually comes with a filter if I buy it with a coupon.

Car has been at the stealership for three weeks. Same transmission TC seal leak. Bolts and seals also needed replacing. Car is 45 days old with 4K KM’s.
