With the RunQuick oil change system you can replace the oil in under 20 seconds, even while the pump is running without losing vacuum. Plus the extra wide base helps prevent tipping and spilling oil. Four in-line ports give you tidy hose routing for three different size hoses. Place the cord on the handle for tangle-free storage and easy hoisting.
