Lead in oil

Thanks for the response. I believe the engine block is indeed iron.
I've been running Mobil 1 5W-40 for the most part, and will look at
chaging the weight. The first oil change I went 10K on synthetic, then
bumped it up to 12.5K at the suggestion of Blackstone.
The engine uses a bit of oil -- takes a quart or so every 1,500 miles
or so -- so I figure I'm adding so much oil that going with long oil-
change intervals isn't so bad. :-)
