Its the time of year. What about ALL the single quarts of House brand oil(NAPA, AutoXtras, Auto+, etc) that are made and packaged by Ashland/Valvoline oil, that keep millions of vehicles going one top-off quart at a time? Vehicles with 26,789 OCIs that are running 1, or 2, or 3 quarts low for weeks, months on end, that then see a bit of light when they are topped-off with Ashland House brand oil, and keep on going until the next top-off of Ashland/Valvoline oil. Sometimes at work, when marking out where a Shower/Tub Shower is going to be, I write VALVEoline on the bottom plate in big to slight decreasing size of letters, showing where the Valve is going to be(Right hand or Left hand, or both, or centered or offset). Many a work truck has led this life.
