This Opti-Lube Opti-Box is the ideal way to store your Opti-Lube fuel additive. Sized perfectly to fit 6 8oz. bottles or 8 4oz bottles, the box also has a locking lid with an integrated gasket.
Fuel additives have a strong aroma, and those with hatchbacks or wagons know that smelling fuel additive while driving down the road is not a great experience. The integrated seal will limit or elimate these smells. Better still, if one bottle has a small leak the box will contain both the leak and the smell.
