discussed heavily on BITOG, small company, you must order online.. LC20 is an oil additive for the crankcase, supposed to add lubricity and help keep things clean. FP60 is a fuel additive that is supposed to keep things lubed and clean as well.

I've been using them on my new Yaris and my wifes Civic and have noted some mileage improvement and smoother running engine. I used to just use Marvel Myster Oil as a fuel additive in the civic and my truck, the smoothness part was cool, but not really any mileage changes (unless i overdosed, then the mileage went down).

Check out the additives section on BITOG, loads of info.

I've also used Auto-RX, and since i haven't done any UOA's with it i won't ever really know for sure, but with so many people reporting great results (or at least nothing negative) i felt confident i wouldn't at least hurt anything.

Just put 4 oz Valv Synpower additive in both cars.

Might be a good idea to TRY to mix or shake this stuff up some before using 4 oz....I noticed some darker stuff (moly) settled in the bottom of the bottle.

If you used the full bottle...wouldn't need to?
