Lucas Response To Zinc Additive

The Lucas rep said 5200 ppm with a full bottle. If you take 1/3 of the bottle you would end up with roughly around 1750 ppm. Close enough for me to 1200ppm. (did I do this right?)
More cannot be as bad as not enough. 1 cam/lifters already destroyed

S0me of the engine rebuilder's qouted on the thread recommended using the whole bottle.

By the way the Rep may have been French Canadian ???, spelling errors happen all the time as a lot of my customers are French. When I reply on some of the letters I get from them the spell check setting is embedded in the letter and tries to correct to French spelling and you can get some goofy corrections
