By me saying hypermiling, you must be thinking I got 50mpg by drafting behind a truck downhill or something. But really considering how this car performs on the fuel economy spectrum, I still did pretty good without much effort. So I drove 265 miles without flogging it and keeping cruise control set to 75mph. This resulted in a fuel usage of 11.22 gallons which calculates out to 23.6mpg! That is a new record, my previous best being 21 with the cruise control set to 85mph most of the way on a similar trip. Now I certainly could have upped the tire pressure to probably get that to a solid 24 but I’m still impressed either way. It helped that I left home at 330am for my 5 hour drive to Mammoth so there was no traffic.

Now I’m here for another day of skiing after today’s long full day of shredding. I’m super tired but the spring conditions are excellent.

Me: should I tell him I beat this easily with my rotary engine?

Inner self: Nah, let him have this. Don’t be a dick.

Me: Yeah, you’re right.

What kinda of oil temps do you get cruising at that speed? I end up 201-203 at 65-70mph, which seems a bit high to me..

*whistles along in 50 mpg Fiesta ecoboost that covers 600 miles on a 12 gallon tank*

Could be worse. So much worse. Can’t show them up that bad, though.

Meanwhile on the other end of the Fiesta range...

you’re doing it wrong

STi fuel ‘economy’ should be single digits

are you sure the decimal point is in the right spot?

I suggest taping the front vents for better aero.

That’s about what I see from my XT as well

I normally get 22 highway and 15 around town..... but once while moving my brother managed to get 29mpg driving my STi....by drafting the moving truck I was driving..... We were trying to see which vehicle would need gas first....it was a drive we normal did with out stopping for fuel in my wife’s Tdi. San Diego to Lake Tahoe.

I prefer to measure gallons per mile. I haven’t tracked the car so I’ve never really seen worse than 17mpg

Well I don’t have an oil temp gauge. I’d think my OBD reader could pick that up but I’m not sure.
