Switch from conventional motor oils to synthetic. Synthetics resist thermal breakdown, reduce engine wear, and include additives that prolong engine life by reducing wear—keeping you on the road longer between tune-ups.

The express-lube shops are fast unless a bunch of people happen to show up as well. They will put an oil in your engine that won't last very long and you have to return to do it all over again. Tired of doing this over and over? Make the move and switch to the best synthetic motor oil recommended for your BMW 635CSi. Don't visit those quick lube places but prefer the dealer? Well some dealerships require an appointment or if you just show up you will probably have to wait for hours to have your vehicle serviced. Amsoil Signature Series oil provides superior protection and can last up to a year or 15,000 miles (heavy towing, idling, dusty area) or even more depending on your vehicle and if conditions are normal (25,000 miles under normal environment) and as a result, this will save your valuable time and money!

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!
