I use Pennzoil 0W-30 Euro Platinum, and a Castrol CAS3593 filter every time, and change my oil every 6000kms which is about 3728 miles. I have heard good things about the efficiency of the Castrol filters.

Pros: good efficiency
Mileage: 6000 km
Part number: CAS3593

AMSOIL Oil filter

With a good filter (Fram synthetic endurance, Purolator boss, Amsoil) and a modern high performance oil such as Amsoil signature and Pennzoil ultra platinum you are good for at least 17.5k with the Amsoil and 12.5k with the Pennzoil under 'severe' conditions.

Pros: good filter, high performance
Mileage: 17500 km

AMSOIL Oil filter

I'm currently using Mobil 1 ESP 0w-30 and an Amsoil filter. 2024 Rav4 Prime XSE with 44,000+ miles. Several used oil analyses flagged high fuel dilution so I want the thicker Euro oil in there and also change it early every 5,000 miles.

Cons: high fuel dilution
Vehicle: Toyota
Mileage: 44000 km
