So April 13th im insuring my mustang for the spring and summer and when I do I want to do a synthetic fluid swap, so im wondering what are some opinions on synthetics what should I change beyond oil and transmission fluid and witch brand do you recommend for our cars I have royal purple on the brain
I knew a head for a oil change chain who said they investigated royal purple at one point, turns out it wasn't as good as the other oils available at the time. Supposedly, the guy that made royal purple was a relative of a head of the Illinois state troopers and a rule was made that all the troopers had to use royal. That's the only reason royal got successful. They made a really good marketing campaign focused on the right people and the purple oil sold.
