Carbon cleaner and injector cleaner that actually freaking works

[PetroleumJunkie412]

I've been wanting to scope my cylinders to see how much carbon there seems to be in them to know if I need to do this because of my Pinging with low octane but alas no luck getting my hands on a scope to do so.

I have seen others scope their cylinders and use Seafoam to some good effect.

I've done the scope.and seafoam a few times. Removed 20-30% usually.

The CRC stuff works much better.

Neither can put a patch on the ass of this Liqui Moly stuff.
