I live in California, with its very stringent emission controls. Every two
years I dread having to pass the emissions test because my hydrocarbons are
always just a shade under the permissible amount. I bet, this year they are
going to nail me.

I am driving a 1993 Chevrolet Lumina Four-door with the 6 cylinder engine
and 90,000 miles. Running fine, year after year.

Is there anything I can do, like adding some chemicals to my oil, to reduce
my hydrocarbon emissions?

Thanks for any help
