| I recently drove 436 (mostly highway) miles on just under 14 gallons of gas, that's just over 31 MPG. | |
I recently returned from a 4035 mile driving vacation to and from central Texas stopping at Santa Rosa, NM; Flagstaff, AZ; Las Vegas, NV; Ukiah, CA (100 miles north of San Francisco); Winnemucca, NV; Provo, UT; Durango, CO and Albuquerque, NM. This involved driving through mountains ranges (8000 ft. elev.) and deserts (with temp. as high as 116 degrees) as well as more "ordinary" terrain. I began with the odometer at 5873 and ended with it at 9908, having stopped for "10,000 mile service" in Albuquerque at 9400. Overall mileage for the total trip, which included nearly week long stays and "city" driving at two locations, was 32.6 mpg. Mileage for those days involving almost entirely highway driving ranged from a low of 31.8 to a high of 38.1 mpg and averaged 33.9 mpg. So a typical highway drive was around 34 mpg. The car responded well under all conditions and never hesitated to maintain constant highway speed when climbing mountains. I continue to be more than pleased with this exellent car!

This is my 3rd Acura (had 2 Integras previously). I've had my TSX for 3 weeks and I'm averaging 25 mpg already. I think that's pretty good for a start. What I don't understand is why premium gas? My TSX is 4-cylinder - why premium gas? My Integras both used regular. Does anyone have an answer?

That was extremely informative and helpful -- another question -- what speeds do you usually maintain on the highway? For instance, I typically run between 5-10 MPH over the posted limit. If the limit is 65, I'll be 70 - 75. Thanks, Jeff

Will take a stab at it. Have always believed that the compression ratio dictated octane -- the higher the ratio, the higher the octane needed. For engines to be tuned to the highest possible output for power, they had a higher compression ratio and would require higher octane. When an engine runs with lower octane than required, they will knock and ping. When equipped with an anti-knock capability (more modern engines), they will sound fine but run at lower engine power output and also consume more fuel. For engines tuned to lower octane, it does not help at all to run a higher octane fuel. In my experience, it is a waste of money. (Also may not be all that great for the engine.) It's usually best to stick to the manufacturer's recommendations for fuel. Lastly, it seems that many of the engines that require premium fuel list 91 octane as the minimum. Most gas stations I go to have 87, 89 and 93. I always wonder why we can only get 93 v 91. Oh well.

I picked up my TSX in May 2003. To date I have put on just over 42000 km's (Sorry to everyone who's unfamiliar with metric, it's what I know). in the beginning I was lucky to get 450km to 55 litres of fuel (Sunoco Ultra 94 Octane, nothing else has ever gone in the tank!). Ibelieve, unlike some of you who feel it takes about 5-10k miles to work the engine in before getting optimum mileage, that it takes that amount of mileage to get rid of the heavy foot syndrom we all get when we get a new car. Since the beginning of 2004 I have averaged approximately 600km to 55 litres of fuel (9.2l/100km for the guys who know what I'm talking about). I do an approximate 50:50 split between city and hwy. I don't like talking mpg with fellow Canadian's as our gallon is based on the British system and is larger than the American one. That fact always makes Canadian mpg number's look better than American. By the way after today's Air France crash at Toronto's airport and being stuck on the 401 for over 3 hours, I think that this tank's mileage will be a "little" below average. Thank God no one was killed. Have a good one guys and I hope this helps any perspective buyers. It's too bad that Ultra 94 is $.14 more expensive than regular now. It used to be $.12. For you guys in the States, you think your gas is expensive come on north of the border. I'm paying $1.04/litre (just over $3/gallon I think). I think it's time for me to take another trip to Europe to make myself feel better about Canadian gas prices.
