I made the switch to Royal Purple today. I didn't know it was actually purple til now. I went with the HPS 5W-30. I will start buying it online from now on -- def cheaper than Orileys. Seemed surprisingly "thin" for oil. :shrug: While the car was jacked up, I switched back to the drag radials. Seriously hoping I get my lift up and running soon.
I also switched to a Royal Purple filter. The inside looks significantly different than the Ford Motorcraft (stock) filter. Anyone have any issues with the RP filters?
