Engine oil Castrol or AMSOIL

I've been using Castrol Edge 5w-40 for years and have had good results, but wondering what others are using. I initially used Mobil1 0w-40 but got a lot of lifter noise which disappeared after switching to Castrol.

Castrol 5w30 high mileage performance, keeps the sucker in tiptop shape

My 25 year old Camry requires 5W-30 and I use Castrol Edge. I also put 1 litre of Castrol GTX 15W-40 oil into the mix - it's supposed to have anti sludge properties and also lowers the overall cost.

From my experience with a Toyota echo; does not matter the brand, only the type. My echo was a 10w40 semi synthetic. once she started consuming a little more oil, I was then just filling her up with any 10w40 semi synthetic I could afford. There was no difference of her running on Castrol vrs the mixed bag of what it ended up with, as I always put Castrol as my oil of choice for a complete change.

Have used a few brands, I think it’s running Castrol 5w40 right now.

Castrol 5w40 Euro spec, my car runs better on that than 5w30

I'm over 50 K on my current Amsoil change. I drive my car a couple thousand miles a month for work. I also put Archoil additive in it when I did the change.

AMSOIL Signature Series 5w-30 with a black JDM Subaru Filter is the superior combo.

I tried using valvoline, that burned noticeably faster. But castrol high mileage has been pretty good.

Dude omg yes. I work at O'Reilly's and this castrol pisses me off.
