it will only if your car requires 89. If your car is designed for 87, then 89 will provide no benefit.
Yes. The higher the octane rating, the better the mileage you are likely to get.
The Acadia only needs regular 87 octane fuel. It is a myth that Premium will give you better mileage, power, or performance than Regular. If it is pinging on 87 octane then something is wrong with the timing of the engine.
i found with mine, that if you used 91 octane you get worse gas mileage than with 87, you also have to remember the KZ models are old and when they were running the streets the most common gas was 87 octane 91 was pretty much race fuel. so if you want better mileage i would probably go with 87.
Bicycles give you more gas mileage.
Octane rating is simply a relative measure of how much octane (which is a chemical substance) is contained in gas. The only way to do it properly is to buy higher octane gas. But buying higher than what your manual recommends is completely pointless. Contrary to popular opinion, you will NOT get more power, you will NOT get better mileage, and it will not run your engine cleaner.
octane spear is better than recra . sper is light cycle and good for stunts
not at all you're essentially making 89 octane. Using a higher octane than the engine was designed to burn is a total waste of money. It will provide no benefit whatsoever. No better mileage and no more power. It is a myth that is does. In fact on modern cars it may make it harder to start. Use what is recommended by the manufacture.
i header is much better than a manifold better it will give you increased air flow horse power and gas mileage
it's a little better than 87 octane but not really high test gas, 91 and 93 octane is the high test.
Exactly the octane the engine was designed to run on. If your owners manual says, 87 octane, then use 87 octane. If it says 89 then use 89. The use of a higher octane than the engine was designed to use is a waste of money, and will provide no benefit whatsoever. No better mileage, no more power, nothing at all. It is a myth that running premium in an engine designed for regular will improve performance.
Use exactly what your owner's manual lists. Using a higher octane than your engine was designed to burn, will provide no benefit whatsoever. No more power, no better mileage, and in fact can provide poor starting, and in some cases, harm the engine. Besides the fact you are paying more for high octane fuel you do not need. Using a lower than required octane can cause less power and pinging. This can eventually do damage to your engine. It is a myth that a higher octane fuel provides any benefit to an engine not designed to use the higher octane.
Yes, diesel trucks generally get much better gas mileage than regular gas trucks. They even sometimes get better gas mileage than hybrid trucks.
