If you use Mobil 1, head to this link to grab your rebate. You can buy up to enough oil to basically do 2 oil changes on most vehicles. Even though Walmart isn’t listed in the participating vendor section, they do honor the rebate. So that means your 5 qt jug of oil ends up being ~$13 after rebate. Current rebate cycle is valid through May 31, 2018.
