okay... something is SERIOUSLY wrong with my MPG

Have we considered winter gas formulation (+ % ethanol mix)? It's been known for this type of gas to actually make it into the more southern states causing all sorts of mileage drop reports. Perhaps a combination of issues relating to your last service in addition to the gas formulation could account for such a drop?
I assume that all other things remain equal including your driving attitude & regimen.

Just as a side note: Depending on the type of "hybrid" failure, the HCH will continue to run for a short while but definitely not for very long at all. Also while doing so, it will likely behave like a snail and the instrument cluster will be lit like an annoying Christmas tree.

Re: okay... something is SERIOUSLY wrong with my MPG
Sorry, but I believe it is physically impossible to achieve 35+ MPG at 80MPH in our cars unless you were going downhill w/ a tailwind in both directions....
Our cars are pig-butt heavy and require a lot of HP to keep it moving at that speed in choice conditions (flat road/no wind). That is why so many people pump up the tires to reduce the rolling resistance.
I would be thrilled to get 32mpg @ 80MPH on a normal highway long distance trip!!!
Relax the right foot a little.....

Most would also say that 41 mpg on a saturn sl is also not possible. The sl has an all aluminum engine and very sensitive to temperature or lack there of. Not only did I lose 6mpg but also noticed oil burning when i switched back to 5w30. The thicker grade 10w30 blew out all the piston / manifold seals. I think when you are dealing with an all aluminum engine, small 1.9 liter SOHC , any change in oil grade will have an impact. I am aware that the 5w -10w first number only represents the cold starting temperature viscosity, however the change in mileage was real also. The NAH should not be as sensitive however, going from 0w-20 to a 10w-30 will most certainly have a impact on FE

Many engines are all aluminum, with an aluminum block and head. It's very, very common on imports these days.
No, 10w-30 will not blow out the piston seals or manifold seals on a S-Series. We have people running viscosities of 5w-30 to 15w-40 on SaturnFans with no effect on the seals. Intake manifold gasket failure is quite common the 2000+ S-Series with the different manifold setup and is not related to oil.
As far as oil, Saturn S-Series 1.9L engines burn a ridiculous amount of oil, regardless of oil grade or past maintenance history. It isn't uncommon for well-maintained engines to consume 1qt/1000 miles. It doesn't seem to have an effect on durability though, as we have on guy with 515k on his 95 SL2 but consumes 1 qt every 200 miles!
Sorry for the off-topic...

Re: okay... something is SERIOUSLY wrong with my MPG
Well then, something else caused my 6mpg drop in fe. And something else caused me to have to replace the manifold gasket at a cost of $1000. And something else caused the piston rings to malfunction causing the oil burning. I blamed walmart for putting in the wrong grade oil, thats when all my problems started. Thanks for your input, I am really going along with the old addage that oil is the blood of the car. Perhaps this may be a good topic for the mythbusters to try...

Re: okay... something is SERIOUSLY wrong with my MPG
Please take a look at the weight difference between your Saturn and our NAH and I think you will understand!
Or I could channel Albert and have him explain the whole E=MC*C thing for ya....
