Is there anyone that uses Royal Purple XPR in their daily driver? I have considered starting to do this ,and running it all 12 months. I do tow 3 days a week,and I'm also driving in a smaller size town of 100k people,where it's mostly stop and go traffic and a lot of braking and re accelerating. I live in Florida. My only concern is the winter months,where I've seen Youtube videos where Royal purple doesn't do well on the cold pour test compared to Mobil 1 and Pennzoil Ultimate Plat. Winter months is usually about 2 months ,and usually gets as low as the 30's and 40'. I have seen it get in the upper 20's and that cold for Florida. I drive a 2008 Nissan Titan, 5.6 liter 4x2 crew cab,with the flex fuel engine. Currently has 130k miles on it.
