I'm comfortable, very much so, that anyone following my advice will have the knowledge to do so beyond the requirements of a community college.

Yes, for an I4, horribly POOR....!!
 
Isn't the CX-7 due out soon with a non-turbo I4...??
 
That will be a good point of comparison as to just how wasteful a factory turbocharged engine is, can be.

#50 of 55 Brand new out of the box MPG by hms1

Picked up a brand new 2010 RDX base 2WD in Atlanta last week and drove it directly
Clearwater, FL. I was following a friend towing a jeep behind his truck so our speed never went much over 70. The highest the computer got to was 29.6 and the average, when getting home, was 28.4. I was really impressed. Don't know what it will be at my usual 75 to 80 mph highway driving. The city driving, which hasn't been much in this car this week, has lowered the computer mpg to 27.5. Still running on the gas purchased in Tifton, GA about 300 miles from Clearwater. Turned in my leased 07 MDX and even made $1300 on the lease. The car is for my wife, downsized for $$ reasons and purchased this time. Wife loves the RDX. Hooray! I like it too.

#52 of 55 Premium Gas Requirement by duncan01

Jul 22, 2010 (6:40 am)

I just picked up my new 2010 RDX last and did not realize that it required premium gas. That information may have changed my purchase of the RDX. Is it truly a requirement - has anyone use regular instead? Any negative issues with using regular?

With turbo, you really need to use premium. I just traded in a 08 tsx that stated premium, we put in plus for 49K and had no problem, but a local acura service manager told us it would be fine. That being said, I will only put prem in the rdx, we have 93 octane locally. At 20-25 cents more per/gal you most likely will get an extra 1-2 mpg which will make up your difference. Don't sweat the prem just look for cheapest/brand name gas in your area.

Required or RECOMMENDED..??
 
With the advent/use of the new knock sensors the engine control ECU will simply enrich the A/F mixture if need be to prevent knock/ping.
 
But you're in for some rather HORRID FE in any case.
 
In order to accomodate the turbo boost when you use it the engine is derated when off-boost, 98% of the time for most of us.

Other than engine lugging, fuel grade, regular or premium, only makes a difference when you are putting a full charge in each cylinder, basically only when WOT. And how much time, overall, do YOU spend at WOT....?
