How cold does it get there?I am a firm believer in 10w30 for us in FL Pennzoil Ultra Platinum. Seems to do well in my previous NA 2012 Coyote and good in my boosted 2015 Coyote.
The lowest cold start I will see is around 40-45* but that's about it. I always start the car and let it idle for 3-6 minutesHow cold does it get there?
From what ive seen rp hasnt shown to be worth its much higher price over pennzoil. Going to spend that much people should just use amsoil. Far better.Royal Purple works well in the HEAT also...
