Since my vehicle OCI is 6 month (3000 miles) and time for change I was looking for a sale. I ran Valvoline Daily Synthetic Blend 5w20 which held up great as fuel mileage stayed consistent with no oil usage. I almost bit on Napa 5w20 for 16.99 but I decided to see if I could get a name brand. I bought Pennzoil Platinum 5w30 5 qt container for 13.93 on Walmart website. I had to get 2 as mine takes 6 qts and one qt was over 6.00 which didn't make since. I also had to get a cabin filter so free shipping. My vehicle calls for 5w20 but 5w30 when 5w20 not available so with 5w20 being 24.98 or so it is not available for me LOL. I can also change outdoor power equipment as it is time as well ...
