    oil smoke -- any suggestions?

    1994 SLS 129,000 miles - and runs like a scared rabbit - but now the rabbit is beginning to smoke

    My Caddy has always been dealer serviced including oil changes - however lately I found it necessary to change my oil myself. In doing so I used Castroil High Mileage 10-50. Now when I start the engine in the morning I am getting the tell tale blue smoke of oil smoke -- but it is only on startup - which means the oil is leaking down from the heads when the car is idle at night. I am sure it is either the viscosity or brand of oil.

    I had the same thing happen to another car when the originial owner broke it in with Texaco Oil and I switched to a paraffin base Quaker State Oil. The car smoked and then I went back to Texaco Oil - and the smoking stopped.

    I would love to know who make Delco's oil that they use at the service facility. Does anyone have any suggestions or recommendations?

    "Delco's oil"? Never heard of any such thing. I'd check with the dealer to see what they are using or just use something other than what you last used.

    GM Goodwrench oil, and AC Delco Oil, are manufactured for General Motors by ExxonMobil. That means that it is basicly the same as Mobil Drive Clean, or Exxon Superflo. I use that in every GM Product I have, and it works great.
    Thanks, Dave

    Exxon! I don't do Exxon, but all the guys at the marina don't do Exxon. Those bastards dump a couple billion gallons of oil in the water, they won't accept responsbility, and no one makes them accept responsiblity. At the marinis, a guy's boat sank in its slip. They had a barrier around the boat and contained all the oil, and the boat hadn't stayed sank for more then a few ours, so the release of oil and desiel wasn't but a minimual amount. (There is probally more gas and deisel dumped in the water, because of small spills during fillup , on busy Saturday. Even so, they charged him--well his insurance company--$15k for enviromental degradation. And Exxon walks away, keeping its boatload of money in its pocket. The most sad thing is that Exxon is #1 in America, even with it 911ing America, yet people still purchase its feul.

    The smoking started after one oil change? I'd suggest that maybe the new brand cleaned up some sludge buildup that may have kept it from smoking before. I don't know if it could clean up that fast though.

    If the dealer oil brand didn't smoke, I'd go back to it. I've always used Havoline in my cars and never had oil smoke.

    10w-50 isn't the recommended weight oil. N*'s don't wear much, I would go back to 10w30 and not use a "high mileage" oil.
