Singring does that MPHD seem to really help your chain last any longer.I like the stuff so far.I am on my second can.It stays on pretty good.As far as it lasting longer I started using it when I already had high mileage on this chain.Normally I get about 15,000 out of a chain.Maybe this will help it live longer.I have already got 15,000 on this chain and seems to be doing ok.Any ideas on chain life if used from new?
