Hi there:
As a United States based online mechanic service, we’re not that aware of the different climate changes in Kuwait. However, in general, when you have extreme heat, keeping your fuel consistent is very important for overall performance and engine efficiency. A change of fuel from 95 to 91 octane is a rather large jump; so you might want to seek advice from a local mechanic for your application.
How to Identify and Fix Common car Problems ?

It won`t hurt your engine if you use a higher octane fuel. For example, if you use 95 or 98 in an engine designed for 91, that`s fine. However, avoid using a lower octane fuel than the minimum recommended by the manufacturer. Using 91 in an engine designed for 95 or 98 is potentially destructive.
The general rule of thumb is: the difference in fuel efficiency is about 1% per octane rating – 91 and 95 unleaded fuels, for example, have roughly a 4% difference. If there is a lesser price difference between the two, then its highly likely that its worth switching.
The different petrol octane ratings are as follows: Premium petrol has an octane rating of 99. Super unleaded petrol has an octane rating of 97 or 98. Unleaded petrol (or regular petrol) has a 95 octane rating.
The octane rating is used to determine the quality of a fuel. The higher the octane rating the higher compression. That being said, the octane rating of Special fuel is 98; whereas, the octane rating is 98 for Super fuel.
If 91 octane petrol is used in these cars, they run the risk of pre-igniting or “knocking” – that`s when the petrol combusts early and pushes down against a piston while it is still moving upwards during the compression stroke. And that can cause serious damage. That`s the bad news.
Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
What`s the difference between 91 and 95 octane fuel? Put simply, the only difference between these two fuels is their Research Octane Number, with the higher-octane 95 unleaded designed to be more fuel efficient and lead to a smoother engine operation.
These octane level numbers (87, 89, 91, etc.) are a percentage of the fuel`s performance measured against pure (100%) octane. Lower octane gas burns quicker than higher octane, and so require less energy to ignite.
Advantages of premium petrol
Unleaded premium fuel has an octane rating which shows how well the fuel resists pressure and premature ignition. Premium petrol can also help to reduce friction, resulting in cleaner engine components and a more efficient performance.
Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
You`ll also be pleased to hear that all fuels contain some sort of cleaning agent as it`s required by law. if fuels didn`t contain this all of our engines would be clogged up – some mechanics do suggest using premium fuel once or twice on older engines to keep them clean.
Always refer to your vehicle manufacturer`s recommendations before filling up at the fuel station, as the type of unleaded fuel you use does matter. In a vehicle that is recommended to use regular unleaded (91) fuel – you can opt for premium 95 or 98 unleaded fuel. This will not cause any harm to your engine.
The fuel economy of your vehicle may also be affected. If you`re driving a car that takes 91 unleaded and you fill up with a premium 95 or 98 fuel, don`t panic as this won`t lead to any engine damage. You may just not a difference a little less cash in your wallet.
Petrol into a diesel system
A vehicle`s diesel fuel pump operates on very fine tolerances and they`re lubricated by the viscose diesel fuel. Therefore, if you run petrol through a diesel system you`ll strip the lubricant, causing the pumps to run dry and ultimately damage them from the metal-to-metal contact.
If the car is designed for regular — or doesn`t specifically say that the car requires premium gas — go with regular. There are no benefits to putting premium gas in a car that doesn`t need it. Cars that require premium gas will typically specify the minimum octane rating necessary.
No, premium gas does not last longer than regular gasoline in a fuel tank. A car owner might only consider the longevity of a car`s gas if the vehicle has been sitting unused for an extended period.
Premium fuel is more expensive than standard due to its higher rate of octane. The benefits of this increased octane rating include lower fuel consumption as well as better engine protection and performance.
A higher octane number in petrol differentiates premium petrol from regular petrol. In general, the octane number of premium petrol is 91 or higher. Apart from a higher octane number, premium petrol also has some additives.
Higher octane fuel will not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only increases the likelihood that the combustion will be controlled, and your engine will perform as it was designed.
Premium gas is also often referred to as high-octane gas, thanks to an octane rating of 91 to 94. Regular gas typically has an 87-octane rating, and the 88-90 range is considered midgrade. While premium gas drives performance in certain engines, the idea that it`s more fuel efficient is a myth.
Mixing the grades to get 91 or so shouldn`t hurt, but it probably isn`t saving you much money. Using anything higher than your manual recommends probably won`t help your car`s performance – but using lower might save you a few bucks, Leroux says. If you notice knocking, you should switch back.
Simply put, higher octane gas won`t lead to better car performance, more speed, better mileage, or your car running cleaner. Most cars require regular gasoline, and using higher octane means wasting your coins.
High octane fuel is primarily used on high-performance engines such as turbocharged cars because the fuel does not burn prematurely, although many car owners choose high octane fuel for use in their non-turbo powered vehicles. Unless your car explicitly needs the high octane fuel, you may not need to use it.

i put 91 super in my car and is says use 87 premium now my battery light is on. what is going on? 2009 Kia Sportage
ANSWER : Hello – you did nothing harmful. Your car may have a small level of performance improvement for this tank of fuel, but nothing extraordinary. Long term use of fuel with a higher octane level, MAY lead to increased levels of unburned additives in the exhaust and catalytic converter, but we’re talking about 10s of thousands of miles here for any "damage". The engine simply burns the premium fuel as-is, and doesn’t really use the additional anti-knock additives in the fuel. No harm, no foul. The battery light may be a slipping or broken serpentine belt, a failing alternator, or voltage regulator. I recommend a charging system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
Which fuel should I use, 91 or 95?
ANSWER : Hi There,
Octane rating is the measure of a fuel’s ability to resist "knocking" or "pinging" during combustion, caused by the air/fuel mixture detonating prematurely in the engine. Most gasoline vehicles with factory engines (assuming no modifications) are designed to run on 87 octane, but others are designed to use higher octane fuel. Higher octane fuels are often required or recommended for engines that use a higher compression ratio and/or use supercharging or turbocharging to force more air into the engine. Increasing pressure in the cylinder allows an engine to extract more mechanical energy from a given air/fuel mixture but requires higher octane fuel to keep the mixture from pre-detonating. In these engines, high octane fuel will improve performance and fuel economy. Using a lower octane fuel than required can cause the engine to run poorly and can damage the engine and emissions control system over time. It may also void your warranty. In older vehicles, the engine can make an audible "knocking" or "pinging" sound. Many newer vehicles can adjust the spark timing to reduce knock, but engine power and fuel economy will still suffer. As always, it is best to refer to your vehicle’s specific owner’s manual which will indicate the specific octane requirement for your vehicle’s engine model.

I just used semi synthetic oil instead of full synthetic in my 1996 lincoln town car executive
ANSWER : Hi there. If you asked this question about 10 years ago – then yes, you might have issues with seals or gaskets wearing prematurely. However, as technology has improved, the gap between semi-synthetic and full synthetic is not as big. You should be just fine without having problems.
I was already having transmission problems. Will constant use of Cruise Control further deteriorate it? Will it cause CC problems?
ANSWER : Hi, thanks for writing in. The cruise control uses some of the same sensor inputs the transmission uses and can indeed affect the transmission and cruise control. If the transmission is slipping then the cruise control may not control the speed steady. Have the transmission problem diagnosed and fixed then see if cruise control problems go away.
Can i use 5w30 motor oil instead of 5w20 for my 2008 ford fusion?
ANSWER : Ford specifies only one viscosity rating for this vehicle, namely SAE 5W-20. In that specification, which is contained in the Owner’s Manual, Ford states: "5W-20
oil provides optimum fuel economy and durability performance meeting all requirements for your vehicle’s engine." For sure, fuel economy will be degraded if you use the higher (30 weight) viscosity. But, the statement from Ford also implies that use of oil other than 5W-20, such as 5W-30, will reduce the service life ("durability") of the engine. Consequently, I would stick with the 5W-20. Synthetic oil is much preferred, of course. YourMechanic does offer mobile oil and filter changes. If you desire that service, please request an oil/filter change and the responding certified mechanic will perform that for you right at your location. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I have a dodge nitro 2011 , which gas should I use 95 or 91 octane? 2011 Dodge Nitro
ANSWER : Hi there – based on the Owners Manual (Pg. 351-353), the 3.7 L engine requires 87 octane, and the 4.0 L engine requires 89 octane. The manual also cautions against using higher octane fuel than required, as this provides no additional performance benefit. Happy Motoring!
I have a problem of petrol going through to the oil sump and the car backfire and some smoke coming out of exhaust.
ANSWER : Hello. If your oil is being mixed with fuel then you are either getting too much fuel into the engine or you have a serious internal engine issue. Most of the time this is caused by worn out piston rings. If the rings are worn out then the fuel will bypass the rings and enter the oiling system. I usually do a compression test to verify if this is possible. If the compression is fine then I suspect that the computer is commanding too much fuel into the engine which is usually caused by a failure in the computer or an issue with one of the sensors. I use a scan tool to check the sensors first and then test the computer from there if needs be. If you want to have this fuel in the oil checked, consider getting some help from YourMechanic, as a certified mechanic can come to your home or office to [diagnose why there is too much fuel entering the engine] https://www.yourmechanic.com/services/smoke-from-engine-or-exhaust-inspection
