Amazon has Motul 8100 X-Clean EFE 5w30 synthetic motor oil on sale for $32. My turbo vehicle takes 5.5 qts so I paired this with the smaller 1qt bottle @$11.68 for a grand total of $82 shipped with tax. I already get a pretty good deal on this stuff, $45 per oil change ($90 for the 2 + 1 combo, tax & shipping incl.) from a race shop in NJ, so this way I'm saving another $8, which is $41 per change. I buy my WIX filters in bulk from RockAuto.
Other oils may be on sale, but this is the one I was watching on 3C. It does go down to this price every so often, even though 3c doesn't show that. I recall it hitting $32 about a month ago but didn't place an order.
