Synthetic oil


Asked by Mar 27, 2013 at 09:59 PM about the 2011 Ford Escape XLT

Question type: Maintenance & Repair

I have a 2011 ford escape 6cyl with
flex fuel. Someone told me that it
was not safe to use synthetic oil in
my car since it is a flex fuel. How true
is this?  I have always used synthetic
oil and never had any issues.

I never heard that. Check it out at this site.


I don't see a correlation between superior lubrication of your car's engine and its moving parts with Synthetic Oil and the fact that your Escape is Flex Fuel (which is relating to your Fuel System). What does one have to do with the other??


Judge roy if by saying never trust someone how does that attest to you giving answers on here and expecting them to take your advice?


Well put judge. Case closed!

Still I look to my fellow guru's am pretty much in the dark with cars after 1998, but am really disdain this influx of 'soft' interface! can't trust it, can't trust it, for example my MINI battery dies, now I can't open the doors anymore....this kinda modern nonsense makes a guy want to rip someone's hair out!....why 'cause it's convenient, not for you with the 'chirp chirp' letting you know I have money and you don't....makes me want to take my ballpeen hammer everywhere I go-

Is synthetic oil petrochemical or man-made structured isomers?

Synthetic oils were developed by the USAF, actually the Army Air Corps at the time, later re developed by the USAF to tolerate conditions petroleum oils could not.Synthetic motor oils are man made oils from the following classes of lubricants: Polyalphaolefin (PAO) = American Petroleum Institute (API) Group IV base oil Synthetic esters, etc. = API Group V base oils (non-PAO synthetics, including diesters, polyolesters, alklylated napthlenes, alkylated benzenes, etc.) Hydrocracked/Hydroisomerized = API Group III base oils

Between "Bob the Oil guy", Google, and what I knew I came up with that. I am eternally grateful to Tenspeed for showing me about Bob. I learned volumes reading his articles, and had never heard of him before. Judge, note: Hydrocracked/Hydroisomerized in regard to your question

wow. That does not sound wholesome.


I'm sure that someone was a highly qualified automotive engineer. Motor oil is a lubricant and flex-fuel is a motor fuel. How do the two get together? How does one impact the other? Why not call the Zone Office of the auto manufacturer and ask for the Service Manager? We just get dumber, and dumber, and dumber.
