## Customer Reviews

### ⭐⭐⭐⭐⭐ BEST OIL HANDS DOWN!
            
*by S***. on November 5, 2017*

I have used used Valvoline, Royal Purple, Mobile 1 and Schaeffer's 9000. This is the ONLY OIL THAT WILL NOT BURN OFF!!!! You change your oil and when you change again, not one ounce is gone. The mark on the dipstick is the same mark as when you did your oil change. I went 6,000 miles the first change and 8,000 on the second and still not one drop burnt. I even had my samples sent in for analysis to BLACKSTONE LABORATORIES and every single time they said try to go longer they even tested the TBN which is basically the amount of additive left in the oil for Lubrication and it was spot on. My last analysis they said try 10,000 miles and send another sample! They will give you a full report of everything that is in the oil and where the values should be. I will never use anything but Schaeffer's Lubricants.
  

### ⭐⭐⭐⭐⭐ Simply the best oil treatment your car should have and deserves.  Highly recommended by many certified mechanics.
            
*by R***O on January 16, 2018*

This is the best motor oil there is by far.  Has the correct additives to keep your engine clean and prevent gunk and build-up.  The Synthetic Oil can go up to 15,000 (not recommended), but Schaeffer oil quality stands up and beats the brand names.  Saw a test with my own eyes where a rotating cylinder with Schaeffer oil and competitors was put side by side.  Friction was created by a person jumping on the platform and locking the plates together.  After a while, the competitors stopped rotating and smoke came out.  Schaeffer synthetic oil continued to provide lubrication and the cylinder continued to rotate and did not lock in place.  Simply the best and you should switch to feel and see the difference.
  

### ⭐⭐⭐⭐⭐ Quality Product initial Oil Consumption Increase
            
*by R***K on November 6, 2018*

LATEST UPDATE: 275,000 miles GMC YUKON  Truck is running Great! Oil consumption has again improved and Truck is running well quiet and strong!Update: Second case ordered oil consumption has improved significantly! Engine quiet and as indicated by manufacturer after allowing engine to adjust to the new oil consumption has improved significantly!Recently switched to this full synthetic oil from Mobil 1  -Significant increase in oil consumption after first oil change. Tech support indicated this is a common problem when switching oils suggest after 3 or 4 oil changes should stabilize. Two quarts used in first 3,000 miles -very high & expensive oil consumption but high Mile vehicle so will keep monitoring and may switch back to blend? Plan to update rating after next oil changes...
