Been meaning to add pics, just been real busy. I mean the most I've modded the car is 50psi tires and a packaging tape lower grill block lol. I paid my mom to clean the car, she said it took her 4 hours, it was that bad. Overall the car isn't in horrible shape, little busted up, few dents, interior was horrible, broken tail light and a touch on the rear spoiler. My mom missed the rear cup holder when she cleaned it, that gives an idea of what the interior was like, really nasty. Guy I bought it from said he couldn't stand to get in the car because it stunk so bad. Oh the driver's window front track seal is missing for some reason, lot of wind noise because of that, need to see if I can modify one from a camry or something to make it work. Besides the cosmetics, the cat seems to be junk (no emissions testing here), and the radio is aftermarket (JVC, at sometime someone cared about the car). The main gauge cluster screen went blank on me once, hasn't acted up since, if it does I'll be "rebuilding" it with new caps. Steering wheel button lights don't work, 12v aux plug doesn't work which I suspect both of those are just a bad fuse. One light inside doesn't work, both tail lights have bulb issues I need to fix so I don't get a fix-it ticket.
Anyway, the car seems to warmup fairly fast, about the time I get to the post office it hits roughly operating temp for the engine (5 miles) so the trip home it does pretty good.
I just ran over to a friends house to help him with something, and it seems like I got into the super highway mode or something, targeted 45mph but held the pedal steady and it dropped to 44-43mph from the up hill and back up to 45-46 down the hill and was seeing 70mpg. I didn't check the state of charge though, might have been burning off excess battery. Car was partily warmed up and hit around 54mpg to his house (few miles past the post office), and on the way back I got around 57mpg according to the scangauge.
Check engine light came back on too, P0420 again, so I guess the cataclean wasn't able to clean the cat enough to save it. It made a difference, that's for sure but driving around low speed and the code came right back. On the highway at 60mph it must have been working well enough to not flag an issue.
I've only filled the car up twice, so I'll have to get used to the funky bladder system. That's why in my fuel logs I've added start and end fuel level % to see if those figures are consistent at all and if the balder effects the fuel level reading as well. I know on the trip it held on the full bar for about 100 miles, then around 150 it dropped down to 8/10. The % from the scan gauge changed a bit while driving like 5% or more fluctuation at steady speed.
Anyway, I need to read more about this super highway mode, like how to trigger it, what it does differently, etc. I suspect if I can get into that mode more often for longer sections of my trips, I'd see a fair increase in overall mpg. I think I have the warm up modes and such understood pretty well. It doesn't seem to require a full stop for the "normal mode" stage, at least for my car, it just is slower to kill the engine till the full stop.
