I use everything on sale/discounted/discontinued/rebate in dino or syn, 5W20 or 5W30.(5W30 is my go to oil). Now & again if I need something for a particular car like my OPE or my Firebird FORMULA in my sig, I'll buy that. But, even the Firebird I use 5W30 HM.
And yes, I do alternate between the 5W20 & 5W30 dino & syn for summer & winter oils, depending on what I have in my stash and how I arrange them for their intended use.
