ptjones Posted February 25, 2014 Report Share Posted February 25, 2014 Just an interesting note on duty cycle of ICE on my 6K mi. trip I got about 42mpg and 93% ICE. On my record trip of 909 mi., 65.4mpg on one tank I used ICE 29%, EV 71% big difference ICE running time. :) Paul Quote Link to comment Share on other sites More sharing options...
webcontrol Posted February 28, 2014 Report Share Posted February 28, 2014 Just did old change with Mobile-1 full syn 5w20 oil. My last oil change was 5000 miles ago with same kind 5w20 oil. However, I feel like after oil change mpg is lower than before oil change. Is that because 5w20 oil is too thick when it is new? Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted February 28, 2014 Author Report Share Posted February 28, 2014 The viscosity of Mobil 1 5W20 (see below) is slightly "thicker" than the Motorcraft 5W20 full synthetic shown in previous post. Viscosity, @ 40ºC, cSt 49.8Viscosity @ 100ºC, cSt 8.9Viscosity Index 160 webcontrol 1 Quote Link to comment Share on other sites More sharing options...
Smiling Jack Posted February 28, 2014 Report Share Posted February 28, 2014 .................... Even through 2013 and 2014 engine labeled with same part number, they are probably different in some detailed spec, like cylinder tolerance range, etc. ...................... In my experience, a change in applicable specifications or in toloerances would always require an engineering change order and a change in drawing number or drawing revision number.

ptjones Posted March 1, 2014 Report Share Posted March 1, 2014 really interesting Paul, 909 miles round trip? Glad your home safe.No, 909mi. was on a trip to Phoenix, AZ and the first tank was from Newnan,GA to Weatherford,TX the end of Oct. when temps were warmer. Thanks, we're glad too. :) Paul Quote Link to comment Share on other sites More sharing options...
webcontrol Posted March 2, 2014 Report Share Posted March 2, 2014 Thanks for that information. From that, Mobile-1's 5W20 full syn oil is similar to Motorcraft 5W20 blend. What about Royal purple's oil, anybody tested that? I think they may have different additives. Quote Link to comment Share on other sites More sharing options...
JAZ Posted March 4, 2014 Report Share Posted March 4, 2014 Further confounding the situation, Mobil 1 has just released Extended Performance 0W-20, but lists the same Ford specs as the 5W-20, i.e., Mobil 1 Extended Performance 0W-20 synthetic motor oil meets or exceeds the requirements of:ILSAC GF-5API SN, SM, SL, SJFord WSS-M2C945-AFord WSS-M2C930-A Additionally, inputting data for the 2013 at their website returns a recommendation of 5W-20 Extended Performance, while using 2014 returns 0W-20. Everyone's playing hardball with this. http://msg1svc.net/servlet/Pv?c=703d6578786f6e6d6f62696c26733d3230383538266d3d363626743d4826723d4e2664613d30267469643d30 Quote Link to comment Share on other sites More sharing options...

Now, if you select superior protection instead of ultimate protection on the Mobil site, the 0W20 AFE oil comes up again for the 2013 and now also for the 2014 C-Max. Evidently, since Mobil1 now has a EP oil for the C-Max, it shoves AFE down a notch. If you select the lowest level of protection (Premium Protection) on the site, Mobil displays the oils for all levels of protection - Ultimate, Superior, and Premium. BTW, I corrected your sentence above. ONLY FORD IS APPARENTLY PLAYING HARDBALL. I do wonder though why Mobil makes no reference to WSS-M2C947-A (maybe oversight).

plus 3 golfer Posted March 4, 2014 Author Report Share Posted March 4, 2014 For those not wanting to look at the Mobil site, here's Mobil 1 recommendations for the 2013 and 2014 C-Max. ptjones and JAZ 2 Quote Link to comment Share on other sites More sharing options...
webcontrol Posted March 7, 2014 Report Share Posted March 7, 2014 What about Royal Purple 0W20 full sync oil? I saw a lot of people like Royal Purple better than Mobile1 Quote Link to comment Share on other sites More sharing options...
Bill-N Posted March 12, 2014 Report Share Posted March 12, 2014 This today on OASIS; not C-Max specific but none-the-less relevant (IMO): Mar 12 2014 4717 -2014 Fusion and MKZ Hybrid/Energi - Oil Viscosity Specification Change The oil viscosity recommendation of 5W-20 on the oil fill caps on some 2014 Fusion and MKZ Hybrid/Energi vehicles may appear to conflict with the owner guide and other service publications which recommend 0W-20 oil. Both 0W-20 oil and 5W-20 oil are approved for use in these vehicles. Quote Link to comment Share on other sites More sharing options...
webcontrol Posted March 12, 2014 Report Share Posted March 12, 2014 (edited) I checked with Royal Purple oil manufacture. They recommend still using 5W20 for C-MAX 2013, and told me that the FE gain by using 0W20 will not be noticeable. So I will keep using 5W20 fully synth oil.
