Engine oil Castrol or ZIC

Tried both but my car seems to like castrol euro the most. Don’t have to add oil between changes

i recommend u buy castrol fully synthetic gtx. Normal price 160-170 but during offer can get as low as 110-130 with free microfiber towel from castrol. Make sure it is shopee mall castrol. I have already bought 3-4 bottles and used it with no issue.

That's a good oil. I used it before I switched to 10w-50 Castrol.

A3/B4 is a rating for just protecting the engine.

Castrol edge 5w-30 LL is oil with just C3. So it's mostly for protecting DPF. If you have a diesel engine with DPF then this is a good choice. If not something else would be better.

I switched to synthetic after doing a piston soak. Sticking with synthetic here on out. I initially ran conventional Castrol 5/30 then blend as conventional was not available through Amazon and then synthetic to try to stave off carbon build up on rings after a successful piston soak.

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.

Doesn't really matter that much, we ran 0W-20 for a while and now have 0W-30 A5 in our Civic.

I hated the castrol, I could tell the engine was louder with it compared to Pennzoil.
