Im not sure if this is the correct place to post this but here i am. I went ahead and did the amazon pennzoil special on some Pennzoil Platinum 5w30 amd an XG filter even tho the oil was chaged last week. Ill change the oil when the OLM come on on my 10 impala. Question is should i store the oil and filter in a certain place? It will prob b 6 months till my next oil change. Also my car only has a 4 quart sump so 2 quarts of oil ill prob have 4 a year unless i need a top off.
