Can someone pls tell me about the "maintenance" (ie. oil changes/types of oil, etc) of the 3.5EB vs. the 5.0? BobG in VA
Both call for at least synthetic blend with the 5.0 taking 5w20 and the EB 5w30. Most seem to agree that 5,000mi intervals is the threshold for the EB because with a direct injection motor you will get some fuel dilution of the oil. I used to change oil in my 2011 5.0 at 7,500 with no issue but if I had it to do over wouldn't push past 5k given how much I towed and beat on that motor. Nothing really special to taking care of either motor. I'm at 4.5k on my 2016 and did the first change at 2.5k and will change again at 5k then 5k intervals going forward. I know others that just commute could go longer intervals but mine tows too much to be comfortable with it. Everything else from the flywheel back is the same with both motors. And both motors will pull a load believe me with the 5.0 actually getting maybe 1mpg higher while towing heavy loads but the EB just does it with less drama (revs, downshifts, etc)...and my 5.0 had 3.73s and my current truck has 3.55s...same 6-speed tranny.
