1gallon 91 @ 30mpg for $2.29 = 7.6c/mile
1gallon 87 @ 30mpg for $2.00 = 6.6c/mile
Your MP$ is less on premium. 10% less. So 30mpg on 91 oc = 33mpg on 87 oc
The difference after 125,000 miles is $1250. Approximately the cost of the 105 service.
Kris' point gets a little fusy when you look at the same cars they produce for Europe.
Euro Accord regular vs. US Acura TSX Premium only
Euro S2000 mid/premium vs. US Honda S2000 premium only
Euro Legend regular vs. US Acura RL premium only
One might debate that the motors are tuned differently for their respective markets and in part this is correct. However their compressions don’t change and that would be the leading factor for predetonation of regular fuel.
Clearly if the s2000 at 11.1 and 9K red line can run midgrade (our 89) then your TL can run regular fuel. Why? Compare the UK Legend with 11.1 3.5v6 to the US RL 11.1 3.5v6. Both the same motors, same power yet only in the US market is it stated to premium.
Then if you really want to start thinking outside the box, start asking yourself why Honda branded cars here have higher compressions and don’t require premium. Then go one step further and ask yourself why Acura is only in the US/Canada. Might it have something to do with brand positioning and our obsession with status?
Just food for thought. Run what you like but dont be affraid to try regular, it wont damage a porsche so it wont damage our fancy accords.

You cant base results on just one tank either. Also you never answered. You claimed 17 gallons. Did you really run it down to dead empty and put 17 gallons in or just till the low fuel light?

u think u get bad mileage with a 6 cyl sedan? My 2.4L TSX has synthetic oil and K&N filter and does 18-20MPG city. Highway mileage is great tho. I get 34MPG highway and 38 on country roads at 55 mph. No, I am not making the high numbers up. TSX weighs 3300LBS and small engine needs to give an effort into acceleration in the city, but while cruising at 70MPH at 2400RPMS, 2400cc's consume little gas bc they simply have to maintain speed.

IIRC "regular" fuel in Europe and Japan is our "premium"

maybe it has nothing to do with the motor. could have a slightly seized caliper. could have a bad ball joint. any of the rotating parts in the car could have seized and is resisting motion. if your engine is mechanically fine, take the tires off and look elsewhere

Talk about contrasts... I also have a 99 TL, with 125K miles. On a recent trip from South FL to Orlando, doing only 65 with the cruise control on (yes, I'm a slow driver!), the AC on for about and hour and just me in the car, I got 33 MPG. 460 miles in one tank.
A week before that, I did 10 (yes, ten!) MPG in ONLY city driving, very short trips (no more than 2 miles, going back and forth to work) and lots of cold starts.
Yes, it's true, this car sucks in the city but it's a great highway cruiser. With normal, mixed use, I average anywhere between 17 to 23 MPG.
Also, ever since they started using crappy ethanol in gas, my mileage went down at least 30%, and that is NO exaggeration. I'm sure that had I made that Orlando trip a year ago, with NO ethanol in my gas, I could have gotten at least 35MPG. You are luck if you always average around 300 miles a tank.
