Now that temperatures are going down for Newbies you may have noticed your MPG's go down also.  You can expect 2 MPG drop for each 10*F drop in temperature.  So a temp drop from 70*F to 40*F would be a drop of 6 mpg.

Here is what you can do to to get some of that back without spending a lot of money.

 

1. Use some kind of Grill blocking method, Grill Covers, foam insulation or tape. Center Grill opening should be covered all year around, I have been using Grill Covers for 4 1/2 years/ 150K mi. now.  I only remove the lower Grill Cover when going on long uphill grades.            Worth 2-4 mpg's

2. Use 50 PSI in your tires, not much difference in ride quality, but it improves mpg's and your tires wear great. I got 64k mi. on first and second set. Worth up to 1mpg.

 

3.  Oil Pan Heater speeds up ICE heating and heat available for the car heater. The only Oil Pan Heater I could find small enough to fit the bottom of oil pan was a Wolverine Model 9 Oil Pan Heater which you can get on eBay.  You can put one on the back of the block to have a total of 250 Watts, but enough to raise WT by 40-50*F.  Worth about 2-5 mpg on short trips and you have heat almost immediately. YA! yahoo.gif BTW I put a block heater in mine which adds about 400watts and 65*F increase in temp which is great, but it is very hard to installsad.png

4. Park facing the Sun which will keep ICE and inside of car warmer. If you can use seat warmers instead of heater.  Worth 1-4 mpg.  Make trips during the warmest time of the day.  These are kind of obvious ideas, but they are worth mentioning. 

 

5.  Premium Gas is worth 2 mpg in my experience, but may not be worth the additional cost. That is what I use.  smile.png

 

Note: 1. The first time you start the car, cold or hot, HVB charged or not, ICE will start running when you hit 35mph to lubricate Transmission. 

          2. ICE wants to get to 128*F before it will operate normally. With ICE block heater and oil pan heater I have been able to get to this temperature and be in normal mode almost from the start.  I think it is more efficient to use the EV to get to speed so when ICE comes on it is making significant power to move car, charge HVB and heat up up the ICE quickly. smile.png

          3. When temps drop below 70*F it's time to block the top grill to keep the ICE compartment warmer.  This can be done as simple as using clear packing tape from hood down to bottom of top grill or use LEXAN sheet cut to fit the opening.

          4. When accelerating use two BARs on the Empower Gauge, this is where the ICE is most efficient, heats up ICE quicker and charges HVB faster.

          5. Use EV from a start to 15-20mph, this gives good acceleration and is more efficient than ICE at those slow speeds. Remember you want to minimize ICE time and maximize EV time to get good gas mileage. smile.png

Obsessive-Compulsive Disorder (OCD) is a common, chronic and long-lasting disorder in which a person has uncontrollable, reoccurring thoughts (obsessions) and behaviors (compulsions) that he or she feels the urge to repeat over and over.

The whole purpose of this forum is to help FFH owners understand and solve problems with their Hybrids. Some FFH owners are interested in actual experiences and facts as opposed to just opinions.  Pretty sad that when you put info out there to help you have a few members try to put down Posters for trying to help.  I think the old adage applies here: " If You Don't Have Anything Nice To Say Don't Say Anything At All"  :) 

BTW you don't have to read these Posts.

Hey Paul, Thank you very much for the info. Very helpful. I have a couple questions. 

 

Do you run the oil pan heater only or with the Block heater at the same time? 

 

The grill blocking? So you block it pretty much year round with no issues?

 

I'm a noob to Hybrids so any help would be great.

 

Thanks, 

 

Alex

50 PSI in the tires becomes self correcting at some point.  I didn't bother to read the rest of the post.  Did he bother to install a kerosene heater like a vintage VW Bug?  Does he park his car in Arizona at night to keep it warm?

I use my two oil pan heaters all year around, I removed block heater when it started leaking through the plastic center piece. I use Grill Covers all year around and use ScanGaugeII to monitor WT and when it gets to 230*F I will turn on Defroster for 15 - 30 seconds to lower temps to 215*F.  The faster you go the higher the WT will be. I primarily use defrost going up hills on the FWY.
