Can anyone give me the brand name of any additive I can add to my 1991 Saab 900, 2.1L? It's only in cold starts, and goes away after driving for about 10 minutes. My brother-in-law says use Lucas, but can someone give me an exact brand name and title? I do not want to buy the wrong thing, as he says it's about $20 bucks a bottle.

Thanks guys!

It's simply called "Lucas oil-treatment"

Your local auto zone should have a bottle or two sitting on the counter.

Hope this helps...

Are you sure it's the lifter and not the timing chain. Long before the chain needs replacing it will rattle on cold starts and quieten when warm.

If you need an additive Wynnes make a hydraulic lifter additive that works well (always assuming that Wynnes is sold on your side of the ditch)

Don't waste your money on additives.
Change your oil using a 10w-30 synthetic.
If that doesn't work, fix the problem (lifter, chain, tensioner...).
