I have a 1999 Saab 9-3 with 179,000 on it. She runs solid no major issues. She uses oil at a rate of about 1/2 Qt. every 1500-2000 miles and I sometimes get some valve noise at start up or under load. Thus, I was thinking using some of this Lucas Synthetic Oil Stabilizer...
2.1 liter n/a 16 valve 1992 900. 238k.
Is this valve noise? And does this idle sound normal?
