Walmart has a Huge Clearance of Mobil 1 Oils right now All with Free Shipping. Normally i go Supertech because its the cheapest, The only Mobil 1 Im seeing to be cheaper than the cheapest available options is weird ones like 0W-40. But the 0W-20 I need is $65.88/15qt vs super tech 18.50/5qt, so its not cheaper but its close, and its "Advanced Fuel Economy Suitable for Hybrid Vehicles" oil rather than whatever basic Super tech High mileage oil. Would this be worth the few dollars more for some of my cars that can literally drive below 100, often below 50 miles in a month? or would i just be wasting 10 dollars?
