Great deal at Amazon for Castrol Edge Full Synthetic -- [ame]https://www.amazon.com/gp/product/B00JGQLZJ4/ref=od_aui_detailpages00?ie=UTF8&psc=1[/ame]

Even if you get your oil changed, it might be worth buying and bringing it to the place that changes your oil. I bought 2 5qt jugs @ $19 USD per jug.

Saw it on sale in Walmart last week for about that price.

Was wondering whether it's a true Group IV synthetic and not hydrotreated. One online source said that Mobil and Castrol are the only ones with Group IV oils.

Im not sure if Castrol is a group IV synthetic, but the US version of the owner's manual specifies Castrol as a recommended engine oil so I use it.

Certainly A LOT (half price) cheaper than M1 0w20 now. I'm gonna look at it again when time to change the 2 Mazdas next summer.

Had to use Castrol 5w30 diesel version for our VW TDI for 6 years and bought a bunch for my tractor and for the diesel generator using VWs money they gave us as partial payoff when their diesel issue loomed.
