Neither. Higher octane fuel burns slower in your engine than lower octane fuel. This is so the fuel does not ignite prematurely during the compression cycle. That would cause spark knock/pinging. Your engine was designed to run on high octane fuel, most likely because you have a higher compression ratio. If your car has a turbo, that would ncessitate higher octane. Your engine works just like any other car on the road, it just requires higher octane to prevent knocking. Higher octane fuel does not increase the performance of your engine, but it does enable the engine to acheive the higher level of performance it was designed for. Hope this helps.
i just got a new 08 tsx and asked this question on acurazine, people generally said they get less performance and fuel econ out of it with 87 gas due to the higher compression ratio. The engine isnt the same as the accord, its better tuned. Also really the difference is $3-5 per fill up, most people will say if you could afford the Acura you can afford the premium gas. My dad has a Lexus ES that recommends premium, the tsx doesn't say recommended, also his ES he uses regular in and his gas mileage isn't as good as the EPA said it should be.My acura tsx 07 needs premium gas to run, should i feel proud of that or screw?
no, i think youre wrong. check the manual again and make sure to read what the car REALLY needs with watchful eyes. it should say Premium Octane Grade 93 or higher RECOMMENDED, and not REQUIRED. the TSX is a four-banger and should run fine on regular (it shares the same exact 2.4-liter engine with the Accord which uses 87 regular). you should NEVER feel proud to be driving a car that would only limit itself to running greedily on premium, especially at these record splitting gas prices toppling well over $4 for regular, almost $5 for premium and diesel. and no, requiring premium does not indicate that the car is any good on or with the latest technology. good engineering will lead to comparable performance with the best of the best all the while using just regular gas. honda's very own legendary 3.0 %26amp; 3.5-liter vtec v6 engines along with toyota's latest 3.5-liter are good examples of this.
Trust me you can use regular gas. I have a 2007 Audi A4 2.0T Turbo Convertible....I use regular gas and it's just fine. If you use regular gas your acceleration may not be as good as it can be, and the engine might not run as cleanly, but big deal, especially when gas is $4 a gallon and will keep rising.
hope this helps!My acura tsx 07 needs premium gas to run, should i feel proud of that or screw?
The TSX isn't much to be proud of. Sorry. You don't necessarily need premium for that vehicle. Open the gas tank door and read the sticker right under where you put the pump in. That should give you the minimum and maximum octane recommended.
Your TSX will run good on regular 87 octane. My wife owns a TSX and she put regular in all the time. Dont listen to those folks who " have to put midgrade and premium " in their cars. Truth is you dont have to.
can't afford the gas..don't buy the vehicle...
It's a high performance engine so it requires gas with more kick
dude you can use regular gas...
its good to keep you octane level high, but the gas pricese now these days man just use 87 octane
