If you're looking for another year, make or model instead of this 1985 Cadillac DEVILLE motor oil, try one of these similar models below. We try to keep one page for each model vehicle.

Attention Uber, Lyft, and Taxi drivers! Save time and money by making the switch to Amsoil! You will save your engine, save money on repairs also! In addition to this, if you are a Lyft or Uber or yellow cab or taxi driver, you will change your oil less frequently. If you drive full time for Uber and Lyft, instead of changing your oil 5 times a year, you will probably only change it twice!! Sometimes you can go to a shop or even quicklube place and they are jam packed with cars to change. That means even more time waiting and less time making money! So if you are driving Uber or Lyft and want the best synthetic oil to save you time and money then you have found the right page! Check the capacity of your vehicle and due to heavy mileage, change your transmission fluid to a synthetic!
