It was actually the same product, first in a dedicated crankcase additive and later with crankcase directions on #0116 cans. However, we had a few complaints about it cleaning so well that it removed “too much” carbon in cases of moderate to severe neglect to the point that rings would no longer seal well and vehicles that didn’t previously burn oil began to smoke. That said, #0116 is a great product for freeing sticky lifters when used at 1½ oz per quart of oil capacity. Just make sure you add it to your cold engine oil and change the oil after the motor heats up.
