Picked up a 85 GMC Sierra. body is excellent shape. Has 4.3 engine with 192000 miles on it and it smokes alittle no engine noise. Is there any kind of oil additative I could use to help prolong the engine another 25000 miles before replacing the engine. Thanks

If it smokes, the motor is on borrowed time. Just maintain it the best you can and run it till you hear the rod go through the bottom end. Then replace the engine .
No fix in a can. You can use slightly thicker oil, but that's masking the real problem.
