How long does fuel stay good for and does it hold it's octane?

What if you put 87 octane in your Acura TSX?

Using 87 octane fuel in an Acura TSX, which typically requires premium fuel (91 octane or higher), may lead to reduced engine performance and efficiency. The engine could experience knocking or pinging, especially under heavy acceleration, as it is designed to operate optimally with higher octane fuel. While occasional use of lower octane fuel might not cause immediate damage, consistently using 87 octane could lead to long-term issues and decreased overall performance. It's best to adhere to the manufacturer’s fuel recommendations for optimal engine health.

What Type of fuel is recommended for 4 runner 97?

Try 87 octane as long as it does not "ping" excessively

Can you put an octane boost in your range rover if you put the wrong gas?

Yes, you can use an octane booster in your Range Rover if you've accidentally filled it with a lower octane fuel than recommended. Octane boosters can help increase the fuel's octane rating, potentially reducing engine knocking and improving performance. However, it's essential to follow the product instructions and consult your owner's manual to ensure compatibility and avoid any long-term damage. If you're unsure, it may be best to drain the tank and refill with the correct fuel.

Can you use plus gas in a 1991 Chevy camaro iroc z28?

yes you can. the higher the octane "within reason" the less chance of you having spark knock. low octane fuel takes less pressure to detonate. so when you have a high compression engine with low octane fuel it detonates before the piston has reached top dead center. with low octane fuel it becomes unstable as the pressure inside the cyliner increases. you dont have to worry about going up in octane as long as it is unleaded. if you use a race fuel that is leaded it wont damage your engine but will more than likely burn up your o2 sensors. hope this helps.

1986 E350 RV looses power or speed in the mountains or on steep inclines.?

My guess is that you are experiencing a vapor lock problem. It was very common with this E350 series. It is caused by running too low of octane in your fuel. The engine produces more heat with lower octane fuels. This makes the exhaust manifold extremely hot. The fuel lines run right along the inside of the frame, right by the exhaust manifold, causing the fuel to get super heated. As long as you use a fuel with at least 87 octane, you should be alright. In many states, the regular gas has an octane rating of only 85. In those states, you will need to run the mid-grade gas or use an octane booster product.

What octane should be used for a 98 dodge caravan?

87 Octane Regular. Can higher octane fuels give me more power? On modern engines with sophisticated engine management systems, the engine can operate efficiently on fuels of a wider range of octane rating, but there remains an optimum octane for the engine under specific driving conditions. Older cars without such systems are more restricted in their choice of fuel, as the engine can not automatically adjust to accommodate lower octane fuel. Because knock is so destructive, owners of older cars must use fuel that will not knock under the most demanding conditions they encounter, and must continue to use that fuel, even if they only occasionally require the octane. If you are already using the proper octane fuel, you will not obtain more power from higher octane fuels. The engine will be already operating at optimum settings, and a higher octane should have no effect on the management system. Your driveability and fuel economy will remain the same. The higher octane fuel costs more, so you are just throwing money away. If you are already using a fuel with an octane rating slightly below the optimum, then using a higher octane fuel will cause the engine management system to move to the optimum settings, possibly resulting in both increased power and improved fuel economy. You may be able to change octanes between seasons ( reduce octane in winter ) to obtain the most cost-effective fuel without loss of driveability. Once you have identified the fuel that keeps the engine at optimum settings, there is no advantage in moving to an even higher octane fuel. The manufacturer's recommendation is conservative, so you may be able to carefully reduce the fuel octane. The penalty for getting it badly wrong, and not realising that you have, could be expensive engine damage. Does low octane fuel increase engine wear? Not if you are meeting the octane requirement of the engine. If you are not meeting the octane requirement, the engine will rapidly suffer major damage due to knock. You must not use fuels that produce sustained audible knock, as engine damage will occur. If the octane is just sufficient, the engine management system will move settings to a less optimal position, and the only major penalty will be increased costs due to poor fuel economy. Whenever possible, engines should be operated at the optimum position for long-term reliability. Engine wear is mainly related to design, manufacturing, maintenance and lubrication factors. Once the octane and run-on requirements of the engine are satisfied, increased octane will have no beneficial effect on the engine. Run-on is the tendency of an engine to continue running after the ignition has been switched off, and is discussed in more detail in Section 8.2. The quality of gasoline, and the additive package used, would be more likely to affect the rate of engine wear, rather than the octane rating. Can I mix different octane fuel grades? Yes, however attempts to blend in your fuel tank should be carefully planned. You should not allow the tank to become empty, and then add 50% of lower octane, followed by 50% of higher octane. The fuels may not completely mix immediately, especially if there is a density difference. You may get a slug of low octane that causes severe knock. You should refill when your tank is half full. In general the octane response will be linear for most hydrocarbon and oxygenated fuels eg 50:50 of 87 and 91 will give 89. Attempts to mix leaded high octane to unleaded high octane to obtain higher octane are useless for most commercial gasolines. The lead response of the unleaded fuel does not overcome the dilution effect, thus 50:50 of 96 leaded and 91 unleaded will give 94. Some blends of oxygenated fuels with ordinary gasoline can result in undesirable increases in volatility due to volatile azeotropes, and some oxygenates can have negative lead responses. The octane requirement of some engines is determined by the need to avoid run-on, not to avoid knock. What happens if I use the wrong octane fuel? If you use a fuel with an octane rating below the requirement of the engine, the management system may move the engine settings into an area of less efficient combustion, resulting in reduced power and reduced fuel economy. You will be losing both money and driveability. If you use a fuel with an octane rating higher than what the engine can use, you are just wasting money by paying for octane that you can not utilise. The additive packages are matched to the engines using the fuel, for example intake valve deposit control additive concentrations may be increased in the premium octane grade. If your vehicle does not have a knock sensor, then using a fuel with an octane rating significantly below the octane requirement of the engine means that the little men with hammers will gleefully pummel your engine to pieces. You should initially be guided by the vehicle manufacturer's recommendations, however you can experiment, as the variations in vehicle tolerances can mean that Octane Number Requirement for a given vehicle model can range over 6 Octane Numbers. Caution should be used, and remember to compensate if the conditions change, such as carrying more people or driving in different ambient conditions. You can often reduce the octane of the fuel you use in winter because the temperature decrease and possible humidity changes may significantly reduce the octane requirement of the engine. Use the octane that provides cost-effective driveability and performance, using anything more is waste of money, and anything less could result in an unscheduled, expensive visit to your mechanic. Can I tune the engine to use another octane fuel? In general, modern engine management systems will compensate for fuel octane, and once you have satisfied the optimum octane requirement, you are at the optimum overall performance area of the engine map. Tuning changes to obtain more power will probably adversely affect both fuel economy and emissions. Unless you have access to good diagnostic equipment that can ensure regulatory limits are complied with, it is likely that adjustments may be regarded as illegal tampering by your local regulation enforcers. If you are skilled, you will be able to legally wring slightly more performance from your engine by using a dynamometer in conjunction with engine and exhaust gas analyzers and a well-designed, retrofitted, performance engine management chip.

Does a 1978 dodge d100 with a 6.6l v8 truck need a fuel additive?

When you put regular gas in the truck, buy some octane boost and and add the whole bottle to the fuel tank. It gave my 75 360 ci better power and starting. The above answer is incorrect and nothing more than a myth. Adding octane boost will not give you more power nor better mileage. Use exactly the octane fuel the manufacture recommends. Using a higher octane is a total waste of money. Fuel additives are another in a long line of snake oil products created and sold to take some of your money. The only thing you should ever add to your fuel is a can of fuel injector cleaner once a year and nothing else.

How long does it take for 2009 standards of today's 87 octane and 93 octane last before going bad in a sealed container?

Gasoline starts to go bad after 30 days. Without the use of a fuel stabilizer you can use it for up to 3 months but it will loose some performance. This is assuming it was stored in a sealed container full with very little air space. But if you pour in a good fuel stabilizer you can easily use fuel that has been stored for 1 year. After 1 year, I would not use this fuel at all unless you mix it at a 1 to 10 ratio with fresh fuel.

What is unleaded petrol?

Exactly that, it is petrol that is 95 octane with NO LEAD hence the term UnLeaded.Answer:Unleaded petrol is what you have before you add the tetra-ethyl lead (or similar antiknock compound) to the base fuel. The TEL allows a cheaper and lower octane fuel mix to be made.Petrol is combination of various hydrocarbon distillates from very small molecules like butane to very long chained molecules. These are mixed to provide proper combustion in an engine. The rating for this quality is known as the octane number. Leaded compounds, if added, boost the octane rating.

Can you use boat fuel in a car?

If we're talking about gasoline/petrol, then yes as long as it meets the minimum octane required for your car. If you consider "boat fuel" as ethanol free fuel then yes absolutely you can. Using fuel containing ethanol in boats however creates problems.

What is the gas-to-oil mixture ratio on a 1997 Suzuki RM 125 Is it safe for me to use a 104 Octane Booster in the bike?

Number 1 you dont need octane booster in a bike. If you want 100+ octane fuel, go buy racing fuel at $5 a gallon. Most fuel suppliers carry racing fuels or can direct you to get them. Now with that said, your fuel to oil ratio will not change based upon the octane of fuel you run, only your timing will change. On a 125 you should be running a mixture of somwhere in the 40:1 range depending on what modifications you have done. Use a good quality oil like Burris synthetic or Red Line and you will good to go with little in the way of carbon buildup on your piston and exhaust. I raced for many years a CR125R and a TM125R Rotary with these oils in the 15k RPM range and they lived a long life only changing out pistons every 3-6 races with little to no gumming of the heads and pistons.

Will mixing 98 octane and 91 octane affect your car?

no it will not as long as they are both pure gasoline.
