and availability. mobil1. 15w-50. and remember this is a price/availibity post. nothing more. act accordingly. got it? hate to be overbearing, but remember this is a price posting. and i am familiar with 'oil' postings and how they can go arye. in 2003 or so, purchased, literally, 300 quarts of mobil1 for an average price, of , say, $3.00/quart. maybe not exact - but close. mostly target. but did play the game. that other retailers would match price. now. 15w-50 hard to find. and expensive. autozone. in this area. $6.24 the quart. walmart a few cents cheaper. if available. costco? does not carry this 'weight'. any thoughts as to where to purchase at lower price? thank you. oh yes. gibson on order. no vermouth. for those that follow this board.
