Wolf,s head has been around for a long time. I run Castrol full syn with the Wix filters in my 13 and my race cars, never a problem.I own a 2019 ram 1500 classic with a 5.7 l hemi engine. I've been searching for the holy Grail and regards to oil and filter and I think I found the perfect combination. I have chosen to use wolf's head full synthetic oil with a wix filter. Seems like the ticking on the cold start has gone away. Any experience with this oil and filter combination out there?
