New here love the site, thank you to everyone that has posted info and helped guys like me try to make an informed choice. I live in Alberta Canada, hot summers and very cold winters -20C on a regular basis. I drive a 2008 ranger fx4 with the 4.0 SOHC v6, no mods except k&N air filter. I drive mostly city with the odd highway thrown in for good measure. I am wondering if i should use the pp 5w30 or the Castrol Edge 5w30, i read that the edge has a pretty nice add package but the pp is about $9-10 cheaper for the 5L jug, would both oils do the same job for me or am i splitting hairs here, oil is change every 6000km with a wix filter. Thank you for any advice, sounds lame but this can be overwelming to newbies. Thanks again.
