I have a question too, I did their 'recommended' oil for your vehicle.....I did a couple cars. One is a 2001 Chevy Lumina, and it gives you the premium a standard then an alternate. For it, it said to use Pennzoil Platinum 5W30, for standard use Normal Pennzoil conventional, and alternate was high mileage.
I then did my 2007 Ford Taurus and it was odd, it said premium choice was 5W20 Pennzoil Conventional and the alternate was high mileage 5W20. Why would they say no the Platinum for that vehicle? Does Pennzoil Plat not meet a certain FORD spec for that year, etc? ODD
