Just noticed today that Kragen has Mobil Clean 5000 on sale for $.89/qrt after mail-in rebate. I just picked up two cases of Chevron Supreme and two cases of Shell Formula the other day ($.49/qrt), plus I have a couple gallons of Delo 400 sitting around, and about 35 qrts of Trop Artic synth blend sitting around as well. Should I grab a case of the Mobil Clean 5000 or just stick to the Chevron and Shell stuff? It'd be used in either my mom's 01 Tahoe or my sister's 05 Civic. I should add that we go through oil pretty quickly (about 30 qrts a month between several vehicles)
Thanks
