Engine oil Castrol or OEM Mazda
Castrol mangnetec gave me good performance but in city conditions it gave inconsistent fuel economies for me and under normal cruising speed 80-90 it performed really good. But for me it felt like reaching higher speeds above 100 felt slower compared to shell. Initial pick up of my car felt higher with this oil.
I have a 2012 civic with 220k miles still use Castrol 0w-20. I've been using it since 500 miles switched to the high mileage stuff around 100k
Castrol Edge is usually cheaper than Mobil 1 and will be as good.
Can use 5w30 or 5w40.
0w40 or 5w40 will give you slightly better engine protection if you drive at high rpms more often.
I wouldn't use anything cheaper or different than those two really. You don't need more expensive oils than those either.
Castrol edge is just fine, even the cheapest one is likely better than whatever was good 20 years ago.
295,000 miles using Castrol GTX high mileage and fram XG filter
Michigan I use 0w20 Castrol Edge all year.
As long as you're not getting cheap gas station brand oil, you'll be fine. I've been using Castrol Edge 5w40.
Mate, just get Castrol Magnatec 5w30 full synthetic and change it every 8000km or 1 year, don't fall for snake oil propoganda
Al producătorului, Mobil1 sau Ravenol în general. E ok și Castrol doar că în experiența mea se înnegrește mai repede și trebuie schimbat mai repede pentru o funcționare lină a motorului.
One time I had the oil bug bite (keera) and I decided to get the best oil. Castrol (I don't remember the number) but it was 340 AED for a gallon. I poured it into the engine and it felt good. That weekend took it for a desert drive and during one of the breaks, the entire oil just leaked out of the main seal. The oil was so good that the engine didn't have the tolerances to hold it back.
