Oil additive update:

I began adding additive into the crankcase of my '76 Impala in Dec of 2008 due to minor leaks from, primarily, the rear main bearing oil seal. In the beginning, there hardly was any noticeable telltale leaks on the garage concrete floor, but as time went on, I noticed some leaks, but the instructions 0n the additive bottle DOES say, and I quote: "If leaks persist beyond 1,000 miles,mechanical repairs may be required". Well, I only have a little over 450 miles on the odometer as I hardly do much driving.

I have quite a way to go before I reach the 1,000 mile target so I will have to keep on adding the additive at each oil change. Larry
