    I bought the CMAX for gas mileage and the Michelin's Energy Savers are part of the reason for the best MPG's. I don't understand why people don't think they don't do that well in weather conditions. They worked fine for me driving carefully and 85k miles with 50 psi and going for more. :) Paul

    I really think 50 psi is the right pressure to use. Were they wearing on the outside edges? Are your roads real ruff/abrasive? :headscratch: I have 85k on mine, might make 90k miles. :) Paul

    If you got it, use it, but I wouldn't install one again, there is barely enough room between the block and exhaust system, what a pain to do. I have two adhesive stick on oil pan heaters, not as good, but it works. Paul

    I put one on my CMAX SEL and it worked great until it started leaking. :sad: It is a real pain to install and remove. :gaah:You only need to have it on for 3 hours max, anymore is a waste of electricity. Paul

    Having some kind of OBDII makes things alot more easier to see what is going on. Last two mornings the SOC went down, 40% down to 34%, 34% down to 29%. Paul

    My example happens all the time, needs to sit for an half an hour. :headscratch: Paul

    Welcome and Good Luck with your CMAX. :) Called and left message.

    This morning I checked my SOC and it went from 52% to 60% SOC.over night. Another interesting thing was I had to get on the gas going to work so the ICE started, I probably went a half a mile with the ICE on yet the MPG gauge was pegged at 60 mpg until the SOC dropped below 50%. Cool :) Paul

    I use EV+ which allows the SOC get down to 32%, I watch the SOC with my ScanGaugeII all the time and this is what I see when leaving home in the morning. When I start the MADMAX the SOC shows the SOC from the previous night first and then current SOC, If I stop with 40% SOC or lower the SOC will drop as low as 27% and the ICE struggles to start. If I stop with a SOC of over 41% at night in the morning it will jump up 5-20% depending the stopping SOC, the higher the SOC the more it will go up. I have seen it go from 53% to 80% in the morning. You have to love the ScanGaugeII to show you what's going on. Paul

    How many miles did you get from your Michelin Energy Savers tires and What tire pressure did you use? I have gone through 3 sets with total mileage of 213k miles. Michelin Energy Savers AS are warrantied for 55k miles and at 50 psi I got 64.5k and 64k miles out of my first two sets which weren't worn down to the 2/32", I replaced them because I was going on long trips in snowy conditions and wanted max tread. My third set I replaced the fronts at 78k because of puncture in sidewall. They could gone probably 3k more miles anyways. The rears I moved to the front and they currently have 85k miles and looks like they will make 90k mile unless I have to go on trip in snowy conditions. Paul

    I filled up yesterday and got Premium for $2.63/gal at Sam's Club Buford, GA 13.1 gallons for $34.46. :) With average temps going down MPG's are going down a little too. I started out yesterday at 57.6 mpg with 525 miles on the tank, drove to North Georgia Mountains taking pics of Fall Leaves changing colors and Water Falls. About 200 miles later my MPG's had dropped to 56.6 mpg when I filled up and actual Fuelly 54.8 mpg. If you haven't put Grill Covers on your car yet maybe you should. Oil Pan Heaters help to warm up the ICE quicker too. :) Paul

    Just got this XGauge PID from Linear-Logic for shutters: Grill Shutter Position Commanded (%) TXD: 07E0220707 RXF: 046205070607 RXD: 3008 MTH: 006400FF0000 NAME: GRL It looks like it works. :) Paul

    That time of the year to remind members what can be done to improve Winter MPG's on Post 1 again. ?? Paul

    Make a YouTube video and post a link. Paul

    Have you tried more reply options at lower right of message window? Paul

    I don't think so, it didn't come out of the right when I replaced it. Paul

    I looked and couldn't find any codes for shutter position for ScanGaugeII, maybe someone else can find them. :headscratch: I did email ScanGaugeII service for help. One important note concerning Grill Covers is they don't block all air flow to radiator and ICE compartment. Standard Velcro installation some air gets around covers into cooling systems, also air goes thru top grill to cool ICE Compartment. During the Winter I will add top Grill Cover which adds about 5 *F to average running temps and also I will tape up center Grill Cover to minimize air flow to ICE compartment. :) Paul

    Getting back to topic of getting Great Gas Mileage, I developed Grill Covers to fix the problems with the shutters which they do very well. FORD said the normal operating temps for the ICE are 202 -212*F so if you are running temps less than 202*F you are wasting gas. The opening temp for shutters is 212 to 216*F from my testing. Also my testing shows the best MPG's happen from 210*F to 230*F and the only way this happens is if you are using Grill Covers and I use both about 90% of the time. :) Paul

    I don't think I would worry about inverter fluid, it doesn't get very warm so it could last a very long time. IMO :) Paul

    This is the Grill Covers Thread that shows shutter operations using a ScanGaugeII to monitor WT, TFT, IA and mph. My video wasn't magnified enough to see small 10 degree opening of the shutters, but it was pretty clear they are pretty much closed or open. Only fluctuated when it was at the change over point. "I got my wife to help me video the shutter operations with WebCam, LapTop, ScanGaugeII and IPhone 6+. I have YouTube links to two videos. You can see shutters open at 215-216*F going 65 mph and close at 214*F. Also see A/C vs shutter operation when turned on and off. These videos were done with both Center and Lower Grills covered up and OT of 85*F. Needless to say my wife was a real trooper to put up with those temps and also covered up with black material to get the glare down on the Lap Top. BTW I used a piece of masking tape to make it easier to see the shutters move. Not a professional job, but I think you will get the Idea." :) Video 1: Video 2: If you have a problem you can search you tube for 2013 CMAX Shutter Test Paul

    Going from the info I have from YouTube videos that the shutters are open or closed I think FORD wrote a loop into the ECM program that takes the percentage open value and compares to the fully open value in a program loop and if they are the same the shutters open all the way, if not they stay closed. Like I said before the update with the same setup I could see the shutters move in steps. So unless someone can show a current video of shutter operations different than mine this is the only scenario than makes sense to me. So there is a chance that the shutters never open without Grill Covers. :headscratch: Only with the A/C on. Paul

    I checked My thread: http://fordcmaxhybridforum.com/topic/970-cmax-grill-cover-testing-2-5-mpg-gain/page-1 and anything before Jan. 16, 2013 is gone, but I remember my testing with camera/laptop before update the shutters moved in steps and after update they don't. The update also raised up the temps the shutters open IIRC 5 to 10*F which could help HWY MPG's. My videos show shutters are effected by temps and speed. Shutters only help aerodynamics and heating up the ICE when they are closed. Plus 3 Golfer it would be helpful if you or someone else could video the operations of shutters using ScanGaugeII or other OBDII gauge to compared to my video. Paul

    I did YouTube videos back in 2016 of shutter operations and from the videos you can see shutters are either open or closed, no in between. In A/C operation the shutters are open all the way all the time no matter speed or WT. Link: http://fordcmaxhybridforum.com/topic/970-cmax-grill-cover-testing-2-5-mpg-gain/page-11and post #211. :) Under normal operating conditions shutters open at 210*F at 55 mph and 215*F at 63+ mph.

    Bottom one too. :) Get a ScanGuageII to monitor your temps if you can. :) Grill Covers protect your shutters from being damaged from snow and ice. Paul
