Just my 2¢, I have 2 free oil changes at the dealer for the 2016 CR-V I bought last February and the oil life is down to 30%. When it gets to 20% I'll call for an appointment. I expect the dealer to try to up sell me on engine air filter and cabin air filter and probably a few other things but I will pass on that.
Once the free oil changes are done, I intend to use PUP because it is one of the best when it comes to cleaning and the VVT system has screens that can get clogged. And also PUP has a low NOACK number, even though the K23W Earth Dreams engine does not have problems with carbon building up on the back of the intake valves.
The post about revving the engine high enough to cause the VVT to kick in is something I am going to have to think about. I have been driving this new to me CR-V since February and have put about 3400 miles on it and have never had the RPMs above 4000 and the VVT kicks in at 4600. So maybe I will have to take it on a highway and put it in S mode to get the RPMs up for a little while.
OP, is the engine in your 14 Mustang direct injection? If it is, then the low NOACK number of PUP would be a big plus in keeping intake valve deposits at a minimum.
