Engine oil Castrol or ZIC

Castrol Engine oil

The mechanic is absolutely wrong. You must use a 5W-40 C3 oil with the Fiat 9.55535-S2 specification, I use the Castrol Magnatec 5W-40 C3, which is cheap and easy to find, but any other brand with the correct specification is fine. A 0W-20 oil has insufficient pressure and film strength, and will lead to damage over time.

Pros: cheap and easy to find
Cons: insufficient pressure, damage over time
Vehicle: Fiat

Castrol Engine oil

I change the oil myself...to ensure it's done correctly and with quality oil (I use Castrol Edge). And I go by the oil minder. I do smell gas during oil changes but it's not strong and never in the cabin between oil changes as some have reported.

Pros: quality oil, done correctly
Cons: smell gas during changes
Vehicle: Honda
Mileage: 60000 km

Pros: no issues in 5 years

I have a 2010 civic si, I use shell rotella T-6 5w-40 due to burning issues and one quart of Castrol 5w-30 high mileage full synthetic (I’m picky lol- but my car runs smooth and has consistent oil levels on the dipstick through the weeks after oil change)

Pros: car runs smooth
Cons: burning issues
Vehicle: Honda Civic
