The first big step alone......

I've just gone over the 1,000 mile mark on my car and will be getting a lube plus oil change.

Several people have commented that I should add a product called sea foam to the oil, presumably for its defoaming qualities....

When I went to the sea foam site, they sell it as a gum cleaner that (as I understand it) you don't leave in the oil for more than say 100 miles.

I have been running Shell 15-40 Rotella from Sam's club, with a pint overfill which eliminates the dreaded tappet tango.

I have ZDF additive, but have not used it.

I would appreciate your feedback about the best possible combination here.

FYI engine has 75,000 miles; a new standard oil pump (with bushing) was installed before I got it in April. Gauge pressure at speed is normally a little more than half.....
