It sounds like you are describing an oil called "Arco Graphite". This oil had very small graphite particles in it, and there were also commercials in magazines and on T.V. about it. I have heard some bad "rumours" about Arco Graphite, but since I have no personal ex- perience with it, I don't know if the rumours are true or not. But Mobil One has definitely *NEVER* had graphite in it.... Dennis -- Call-Me: Dennis Gibbs, Univ. of Md. Comp. Sci. Center.

I own a 1979 Pontiac LeMans with the 3.8 litre V6 engine. I used Arco Graphite oil for more than 30K miles (as long as I could get it). I now have 56K miles on the car and it has learned a new trick. This weekend, the oil pressure light started coming on when I came to a stop with the car in gear. Since my brother-in-law is a better machinic than I am, and he has all the equipment, I am going to have him tear it down as soon as possible. I am interested in seeing what the bearings look like and will try to determine if the oil might have been responsible (may not be possible). I'll report anything unusual that might be traced to the oil. Kit Kimes AT&T Consumer Products Montgomery Works Montgomery, Il. 60538-0305 ..!ihnp4!mgweed!kek
