I might change my oil again this weekend with a high mileage oil since I tracked down the source of the oil leak,and give it a try to see if I have success with it. I've narrowed down my choices.
Pennzoil High Mileage (the dino version)
Pennzoil Platinum High Mileage
Quaker State High Mileage (synth blend)
Castrol GTX High Mileage
Castrol Edge High Mileage
I'm leaning towards the Pennzoil dino one because I used it in my 300ZX and I loved how smooth it ran.
The QS one says "formulated to support catalytic converters and other emission equipment". The GTX one says "Phosphorus Replacement Technology to help extend the life of the emission system". What exactly does that mean add pack wise?
