Well I see you went stp which is not as good as OEM. I run amsoil filters and have no issue, I prefer amsoil to OEM because amsoil have tested at a 99 percent particles are filtered out.

Pros: 99 percent particles filtered
Cons: not as good as OEM
Vehicle: Toyota

Rating 5.0

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

Every 4500-5000 miles with Amsoil Signature and Amsoil filter. Do it yourself, it\u2019s not hard and you can be assured no corners were cut. Don\u2019t go beyond 5000 miles. The 3.5L is really hard on oil. It\u2019s cheap insurance.

Pros: cheap insurance
Mileage: 8047 km

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

Rating 1.0

Dont buy a Stp, had my oil changed on my 09 Legacy, a few days later I notice a drip and the usual burning smell while driving . Took It back to mechanic and they said there was a dot on filter so they swapped It out. Burning smell still there but leak was not seen, so I bought a Purolator and changed It myself now no problems.

Cons: oil leak, burning smell
Vehicle: Subaru Legacy
