Sometimes a "
tailwind" is your friend and then all of a sudden a
"headwind" comes and your MPG suffers, then we think "oh my god" is there something wrong with my HiHy!
Is it the gas, air filter or Toyotas crappy product?
Come on ....Dude, your splitting hairs for pennies per gallon of gas??????
Just enjoy the drive. there are WAY TOO Many variables that affect MPG.
If yu don't understand standard engine vehicles, how can yu understand Hybrids and it's technological
"limitations".
All I see is HYBRID owners watching their MPG every 3/10's of a mile and they are on the edge of their seats concerned about MPG going UP and Down and comparing to yesterdays trip, etc.
All these Hybrid sites are the same...posting 2 hour old MPG readings
(like it was some dam contest) along with every comment about their expensive Green Vehicle.
BTW, I am a big fan of the Prius...
Just not the HyHi. The HyHi is a pig on gas for the price yu pay. Toyota should have used the I4( four banger) in it's design for a Hybrid Highlander.
And why did Toyota
Require Premium Fuel in the HyHi when in the standard V6 HL Premium is only a Recommendation.
Anyone knows that Premium fuel always ups the MPG as general rule.
Toyota just wanted HyHi owners to achieve the best MPG at any cost (But premium fuel will really eat your wallet)
Let's flame this

...I'm ready for ya
Oh and BTW I just took a trip around the block in my HL, to get milk, and I logged 20.0956832 MPG. It went down by .07366489 MPG since yersterday morning. Yu think it might be the two gallons of milk that added 10 pounds to my gross vehicle weight thus reducing my MPG? or could it be the gas??
I'm very concerned about this! Please help me
