Walmart can charge more??
Actually VWB and Maxlife as well as both flavors of ST syn are the same price off the shelf. They all get you big time for oil changes though. Think branding of oil is in a big shake up right now. Always afraid that my oil change place will declare VWB a semi syn and decline my stash of ten buck oil coupons.
Think that Maxlife has slightly more robust additive levels while HM ST is identical except for slightly more seal conditioners.
