Gas in oil? - Page 2

DeSoto frank, The previous owner bought it at auction,and only owned it a month. He only rebuilt the pump because the elect one wasn`t working. The owner before him had the car for around 10 yrs and seldom drove it. I`m assuming the oil hasn`t been changed but I`m planning on doing it this week. The oil pressure seems to be fine and stays around the 3/4 mark. This last week I`ve been starting it everyday and running her for 10 min. (probably not too wise on my part) I will add the Mystery oil as you suggested, I don`t want to tear the motor down at this point.
All you guys have been helpfull and I do need and appreciate all the advice. I`m new to this and wouldn`t want to ruin a nice car. Thanks,Bob P

If you can, next time you have it fired-up, let it run at a fast idle (600-800 rpm) for 1/2 hour, leaving the filler-cap off the oil-fill, and letting that crankcase breathe.

Better yet would be a 1/2 hour drive on some back roads.

Once you get it back on the road, a good one-hour run every two-weeks or so will help keep condensation & blow-by from building-up in the crankcase.

Good luck !

Recommended reading: "Drive it Forever", by Robert Sikorsky, SAE. My copy has a pic of a '58 Mercury on the cover.

Has a WEALTH of practical info on theory & practice to extend the life of your car or truck.

EXCELLENT info on the ill-effects of cold-starts, short-trip driving, long-idling warm-ups, etc.

Brief excerpt: each time you start the engine "Dead-cold" (sitting overnight), the initial wear occuring inside the engine during the first minute of operation is equivalent to about 500 miles worth of "highway driving";

Enjoy your Buick !

Frank sounds like good reading material to me! My next trip to Borders (bookstore) I`ll be buying a copy. Sounds a little scary about the cold starts (500 mi) but I`d imagine it`s true.
I hate to hear people racing their motors on a cold start up!
Gratfully appreciated, Bob P
