i would be weary of oil additives. if they were so good, why doesn't any manufacturer recommend them?

this site claims that slick 50 is pretty much just thick engine oil and teflon, and can actually clog passages...

quote:
This conclusion seems to be borne out by tests on oil additives containing PTFE conducted by the NASA Lewis Research Center, which said in their report, "In the types of bearing surface contact we have looked at, we have seen no benefit. In some cases we have seen detrimental effect. The solids in the oil tend to accumulate at inlets and act as a dam, which simply blocks the oil from entering. Instead of helping, it is actually depriving parts of lubricant"
