Even though it says it requires Premium in Summer some where in that manual it states I can use 87~89 octane gas without harming the engine. That is helpful to know. With premium fuel and my mainly highway driving with only 2 persons on board we get 25MPG see full Volvo S80 review

I've had this car for 13 years now and the mpg has always been very good. Being a European model (2.4 litre petrol auto - 170 bhp) it does not compare directly with any US models. I have the air con on 100% of the time. If I keep to the speed limit - 80 -85 on the speedo I get 35 mpg (English gallons!) without any problem. On a holiday trip to Portugal doing long distance driving and at slightly slower speeds - say 70 mph on the speedo - I managed 40 mpg over nearly 1,500 miles. In town stop start driving I will usually get 25 mpg. Impressive figures I think for a 13 year old vehicle weighing as much as it does. see full Volvo S80 review

Very good fuel economy overall but running the AC continuously does produce a noticeable 2-3 mpg decrease in fuel economy. see full Volvo S80 review

One of the big downsides of the rotary is truly horrendous fuel economy. When the RX-8 first came out in the early 2000s, its mileage ratings of 16/22 city/highway mpg (stick shift) were just barely acceptable, but there days, with many crossovers hitting more than 30 mpg on the highway, those figures are truly atrocious, especially given respectable but certainly not neck-snapping power. Futhermore, it takes premium. If you're using the RX-8 as it commuter, fuel costs will add up quickly. In my predominantly around-town driving, I typically average between 16-17 mpg. My highest recorded average was 20 mpg on a highway trip at speeds around 75 mph. see full Mazda RX-8 review

The EPA numbers are way low compared with my real-world experience. The window sticker showed 18/25 and I have never seen less than 23 with my 40/60 city/highway commute. I think Mazda should develop a lean-burn economy cruise mode for this car. see full Mazda RX-8 review

Not that bad for what it is, but it seems to me that Mazda's Sky Active technology could help the city mileage. It just needs more R&D. see full Mazda RX-8 review

For a small engine displacement and a relatively light vehicle weight, the gas mileage is weak. I usualy get around 19mpg, and that does not realy matter if I am doing all city or all highway driving. I think the real problem is in the sixth gear it isnt much different than fifth gear so it does not provide good fuel economy. see full Mazda RX-8 review

For a car with a 1.9 liter engine I would have expected better than 16-19 MPG. Get your foot into it and the numbers fall drastically. Otherwise I loved that car. It just got too small with a newborn and a big dog. see full Mazda RX-8 review
