Been using Mobil 1 10w-30 HM a lot lately in a couple cars. 2012 Escalade & 98 Tacoma. Its available for $22 to $25 at wallys year round. I know they have started carrying a lot of new stuff in the last year or so. Are there any other options for a full synthetic oil that's has a hths of 3.5 > "at around the same price" ? Just curious.
