About this part

Product Details

Not every fuel-system problem needs a teardown. Sometimes you are just trying to clean things up a bit on a driver that has picked up deposits from normal use, and that is where a simple treatment like this fits.

This STP bottle is made for both fuel injectors and carburetors, which makes it handy for a wide range of gas-engine maintenance work. The 5.25 oz size is easy to pour in with a fill-up when you are doing routine cleanup instead of a bigger repair.

It is not magic in a bottle, but it is a straightforward maintenance product when the goal is keeping the fuel system cleaner without turning the job into more than it needs to be.
