I buy Bosch filters through Rock Auto and oil during the Fleet Farm Black Friday rebate sale so my oil changes cost less than $10.

Pros: oil changes cost less

The Euro oil (which I seriously doubt Valvoline used) is about $30 for a 5q jug + $10 for an extra quart, and a Bosch filter about $15.

Pros: easy to find

Vehicle: Audi

I tried to buy a filter, a bosch is a decent choice, but I wasn't able to find it, or I should import it for 100 sar ( which is expensive, most filter sold for 20 to 50 sar where I live - saudi arabia -)

Pros: decent choice

Cons: expensive to import

Vehicle: Volkswagen Passat

I believe there was a technical bulletin about this, recommending that the VW installations of the 1.8T be run the way Audi, who wasn't have the issue, was running them. So that meant using the much larger diesel Rabbit oil filter, like the Bosch 72174, or the Mann or Knecht equivalents, which upped the oil capacity of the engine, and then running only synthetic

Pros: larger oil capacity

Vehicle: Volkswagen

Part number: 72174

So I changed the filter to an $11 Bosch filter, got the car good and warmed up, still low pressure. When I start it up and the oil is still thin, I've got about 50psi and as it warms up it just goes lower until it'S around 10psi at 2000rpm.

Pros: 50psi when oil thin

Cons: low pressure when warm

The current Bosch 3323 oil filters are now made in Mexico and filter quality has decreased. I don't use the current Mexico made Bosch - I cut one open and it was a bit different than US made older ones.

Cons: decreased quality, different design

Vehicle: Honda Pilot

Part number: 3323

Bosch Filter verbaut, hat sich unten die Dichtung am Filter abgelöst und den Ölkanal im Filtergehäuse zu gemacht ???????? kommt also nicht nur bei „billigfiltern“ vor sondern auch bei den nahmhaften Herstellern…

Cons: Dichtung gelöst, Ölkanal zu
