Great product!
Size: 12 fl. oz. (Pack of 1)
Would recommend pouring oil into container after pouring in and shaking it up, great additive recommended by some old folks but I would have to say it’s just thick as molasses. Used in 2016 FORD F150 5.0 V8

Great for High Mileage vehicles
Size: 12 fl. oz. (Pack of 1)
Added into my 2014 Dodge Grand Caravan with 100k miles before a family trip and eliminated knock, slow starts and improved our gas mileage by about 10% I think! super easy to add to the oil and very happy with results.
