Rounded up, it's $25 per jug here in the local WMT, Hawaii, but they're flying off the shelves like crazy. Good thing I got one already for my next OCI.
In June NAPA will have the quarts on sale for around $7. I've been using it to top off my Mag1 Euro 5W-40 and I'm noticing less oil consumption and more responsiveness just after start up. My car was using around a qt/1k miles with just Mag1. Now with just a qt of M1 in there, it's only consuming 1/2 qt. Can't wait for next oil change.
