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
I have a 450k km 1.9 tdi, and a 300k km 1.6 tdi, i always use 5w30 castrol, no issue.
Pros: no issue
Mileage: 450000 km
I would only suggest using \"premium\" oil brands, like Castrol or Elf, in correct specification.
Pros: premium oil brands
Castrol Power1 is really good though
Pros: really good
Vehicle:
Suzuki
Bought my 2020 Rogue at 53k. Just did the CVT service myself at 59k with Castrol CVT Transmax and replaced both filters. Over the last 1500-2000 miles I noticed the CVT working harder via engine revs and a slight decrease in “shift” smoothness. Originally I thought it was from cold Midwest weather. After replacing, the CVT and engine don’t even work nearly as hard. The old fluid was DIRTY as well as the internal filter. The magnets had sludge/grime on them. If you can do this starting at 30k miles vs 60k I highly recommend. I couldn’t be happier and recommend everyone do their own service.
Pros: smoother shifts, engine works less
Vehicle:
Nissan
Mileage: 59000 km
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
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
Castrol is fine
Pros: fine
Vehicle:
BMW
It\u2019ll be okay. Subaru engines are robust and that mix rate won\u2019t increase the viscosity enough to affect the oil flow rate out to the cams.\nPardon my skepticism regarding Castrol oils though. Haven\u2019t been a fan of them since the GTX days. The additives they\u2019d chuck in their generically sourced base oils glazed bores and gummed lifters.\nCost many a machine shop like ours a fortune in comeback work.
Cons: glazed bores, gummed lifters
Vehicle:
Subaru
