Was just down at my local Wally World. Had to pick up some Techron Fuel System cleaner for the Acura in signature. Some guy behind me cleared out totally the ST conventional 5W20 5quart jugs at 17 jugs overall & also grabbed three 5 quart jugs of the ST HM 5W20 to make it an even twenty jugs. We just looked at each other and smiled. I would imagine he owns or works at a small garage. I was watching him to see if he grabbed any oil filters afterwards & which brand/brands but that did not happen. I should have asked him what oil filters does he stock up on?? This is not the first time I have experienced the ST conventional 5W20 totally cleaned out while all other brands are nice & stocked up.
