I'm surprised, you were all well behaved. I was gonna say baby oil, or vegetable but I can't, in good conscience, do that now. Main thing, look at the back of the container. Where the round emblem with the grade listed. Make sure it doesn't say reduced friction or anything that may sound like that.(can't remember the exact wording). Friction modifiers f up your clutches. I usually use Shell Rotella 15-40 diesel oil. Now my wife prefers astro-glyde, but I think I'm getting off topic. Damn a.d.d.
