I have an older car that burns about a quart of oil every thousand miles or so. Do any of the additives on the market that claim to help reduce oil consumption really work? Are they safe to use?

I'd maybe use one grade thicker oil, but your best bet is to use the proper weight oil and check the level weekly. Cheapest route. My Mustang burns a quart every 700 miles. No reason to rebuild at this point. Check your valve gaskets too, they might be helping to contribute to the problem.

I agree with Tom on the one grade heavier, also check your PCV system, sometimes a bad PCV valve can cause oil consumption. The only additive that I have used that had any results was"Restore" but it doesn't last long.
