Wife got this from cabelas and says "DFI" on it. Also says 'synthetic blend', but isn't the
Quicksilver brand full synthetic? Had boat out 3 times and it's ran great...well it ran better with Pure gas in it. It's a ripoff at $34while QS is at BassPro for $19.
I think this was covered once before, but I was sure Mercury Premium Plus and Quicksilver Premium Plus were the same exact oil. The name difference was based on distribution and Mercury Authorizations.
