Do I need to use premium fuel if my car is leased?

it can damage the engine, and it probably wouldnt be covered under warranty so use premium.

using low octane gas gives u less horse power and lower miliage…but do what u want.. compuiter adjusts car to run and it will NOT hurt it.

if you pump premium than you are doing good by helping rental company maintain their cars..make them more durable.
but it also burn a bigger hole in your pockets. choice is yours..
either one car still run normal, though premium may give slightly better power.

if the owners manual says to use premium, you probqbly should. if something happens to the engine you may be held responsible if they know you did not use the correct grade of gas.

If you don’t use premium fuel, you may suffer some damages to engine components, plus the engine won’t run correctly which may cause a severe decrease in fuel economy. You’d be paying more for fuel.

Plus, if you incur any damages, your warranty may not cover them because you’re not using the vehicle to the manufacturers specifications. Or, if the dealership that you leased the vehicle from may force you to pay for some amount of the vehicle to repair damages from not using the specified fuel.

As a personal note, if you didn’t want to pay for premium fuel, why did you buy the car?

I have leased cars before and I have had the same question. You do not have to use premium fuel, yes it is recommended but not nessesary. Theres no way for them to find out what kind of fuel you use. With the price of fuel these days every little bit helps.

If you wanted to save money, you shouldnt have purchsed a 40+k automobile. There is a reason engineers have placed a premium fuel label on that car.

no just as long its 87 octane

premium fuel doesn’t give you more horsepower per say it just burns hotter. if the manufactor recommends it i’d would use it. don’t take any risks.

Check the owner’s manual and the sticker on the fuel filler door, if there is one there. In the USA and many other countries (although, not necessarily everywhere), here is the way the octane numbers generally break down…

87 – Regular
89 – Mid Grade
93 – Premium

or

87 – Regular
89 – Premium
93 – Super Premium,

Depending on the gas station franchise or chain.

Whatever the vehicle calls for is what I’d put in the tank. It is possible to use lower octane or higher octane fuel in a modern vehicle, but using lower octane fuel is not recommended. Modern vehicles have “knock” sensors on the engines to detect “knock” (a.k.a. “ping” or “detonation”). The engine management computer will retard (ease back) the ignition timing to prevent “knock,” which is harmful to the engine. This will rob you of power and economy.

Therefore, if you are running on fumes, the station is sold-out of premium (or super premium), and your vehicle calls for 91 octane fuel, you can put in a tank of regular. But doing this regularly is potentially harmful to the vehicle.

If you must put regular in a vehicle which asks for premium, pick up a bottle (or six-pack) of octane booster and pour the recommended dosage into the tank.

If you’re really concerned about the cost at the pump, maybe you should consider leasing, renting, or buying something else.

Really, you should buy rather than lease. Modern vehicles (especially Japanese vehicles like your Honda-built Acura) are known to last 200,000 miles (320,000 km) easily. Some will last twice that long without an overhaul. One study I read stated that buying a car and keeping it for 10 – 15 years could save the owner US $31,000 ($21,000 outright, plus $10,000 in interest from depositing or investing money not spent on car payments).

But, if you must own a vehicle newer and flashier than your neighbor 2 doors down, lease away, and stop complaining about the fuel costs. You know you don’t like your neighbor anyhow, so why compare your vehicle to his/hers anyway?!?!

My dream car: VW Golf 4 door hatchback (“5 door”) with a TDI Turbo Diesel Engine and a 5-speed stick… Up to 49 mpg EPA estimated fuel economy (depending on the year and options). Diesels can be made to run on regular diesel, bio-diesel, and even used cooking oil. If you ever see a car or truck that smells like french-fries, it is probably a diesel vehicle that was filled up at the back door of a fast-food restaurant.

FIrst of all, you need to know what octane is. Octane in general is the resistance to igniting. (I think) The reason why high-performance engines use high-octane is because they generally run at higher temperatures. If the octane level is too low, the fuel will “pre-combust”, meaning, the explosion occurs too early. This might create engine damage.

So, don’t buy a lower octane fuel for your vehicle. You don’t want any engine “knock”, do you? It could cast you the whole engine. Also, buying higher octane fuel than the recommended octane rating is pretty much useless……
