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.
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.
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.
Use full synthetic Mobil one or Castrol Change every 7k miles. And the oil filter too.
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 -)
Make sure to change the drain plug crush washer if you don't do at the dealer and get good quality filters (Bosch, Mann)
Yes, Castrol gtx and a KN oil filter
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.
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.
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…
