Yep both plugs, we are in SF area my looking at the net I got a consensus of 10/30 since it doesn't get crazy hot here. Should have asked here first apparently. I have spent some time around 911's when I was younger had a good friend with a 74 targa, so I do know how to check the oil. It certainly looks like the sump plug on the motor should drain completely as it's the lowest point on the cover. So even in 87 the motors still need zinc additive? Have to do Brad Penn on the Spitfire, but didn't realize the 911 needed it. My wife's friend was kind of sold on the vintage 911 mystique by the person selling the car, and I'm afraid she's a bit over her head. I showed her how to check the oil when I rescued it from a horror story coast to coast transporter when the car got impounded in Phoenix. Trailer-ed it back here and tidied it up took inventory and noted that the oil level was low then. Topped it up and in about 1800 miles it's sucked maybe 3 quarts. No visible smoke on start up or drop throttle, air filter was fairly dirty but not oily. Did not pull the plugs, because it's not my car. That being said seems to run great and pull strong. What causes consumption on 3.2's, primarly valve seals?
