Rislone, amazing that stuff is still around.
It's been around since the 30's, maybe I remember ads from the 20's. Anyway, it's about 90% kerosene and it was a maintenance chore occasionally used in the day to flush a crankcase with kerosene. Remember this was during non-detergent oils, leaded gas, filters that trapped mostly large particulate, and draft tube breathers. An engine with sludge build-up was a common problem particularly for stop-n-go, short delivery trucks, and taxi services. Flushing depended on mileage, time, or what a rocker cover looked like.
It could help with engine rejuvenation, provided you weren't so far gone you might actually plug something up. But with detergent oils that really got good from the 60's onward, and pcv systems that were a major improvement towards cleaner crankcases beside air pollution control; you're better off , and I mean way better off, following your present course. Trevor hit the nail on the head with his oil/filter recommendations.
