Okay well im about to but a used 2001 Audi TT beside only 75,000 miles on it. All the research ive done says to use ppremium gas just, but does it really matter?
Yes it does. you should always put in what gas is recomended for the vehicle. if a car says regular unleaded next put that but it wouldn't matter a whole lot if you put premium contained by it. but with a car that say to use premium then you have to put premium contained by it or risk damaging your engine. the reason for this is that some cars hold a higher compression ratio requiring more octane to keep the gas from preigniting. if you put regular within then it will most likely start knock causing your computer to back the timing sour making your car run like ****.
Yes it does

You should use whatever grade/octane the owner's instruction book recommends.
Octane is a measure of the fuel's propensity to resist pre-detonation (or engine knock).
If your car is experiencing engine knock (or pinging), then you should progress up a grade in octane. (But if your vehicle IS knocking, something may be wrong with it and it may stipulation a tune-up!)
Higher octane gasoline doesn't mean that it is necessarily cleaner or better. "Premium" or "super" is a mis-nomer. All gasoline sold in the US must collect certain federal EPA clean-burning guidelines. However, some individual brands _may_ decide to put some extra cleaners or do extra refining within their higher-octane fuel (as I've heard of some brands advertising low-sulfur gasoline as singular in their Premium line).
A higher octane gasoline in truth has lower BTUs (energy content) than a lower octane gasoline, so the only means of access that you'd see better fuel economy by going up in octane is if you be previously using lower than recommended octane in your car... (So if your coup¨¦ requires a higher octane fuel, using a lower octane fuel will usually give you lowered fuel reduction...)
For an occasional tank, you could get away near using a lower octane than recommended in a car that requires "premium" fuel, as the saloon will adjust, but it can cause some extra wear on the engine while knocking, besides the lowered fuel discount. (long term use can cause added engine wear/damage)
If you live in a high altitude nouns (like the Rocky Mountains) usually you can use the next octane level down from what is scheduled in the owner's manual because of the altitude/thin nouns with no ill effects (except if you come down from the altitude near a full tank!).
Reasons to use higher octane fuel:
1. Your owners booklet calls for it
2. Your engine is knocking
3. It's the solely way to get low-sulfur fuel surrounded by your area (sulfur will slowly poison your catalyst, making emissions worse over time)
4. You close to spending extra money on gasoline

Red book meaning of of my sports...
If the engine was designed to run on high-octane premium grade gasoline, next YES, it Does matter. Your engine performance will be reduced, and you could in fact damage your engine by running the lower grade stuff adjectives the time. That's not to say that an occasional fill up of regular will craft your engine blow up, but if the compression ratio, timing and other systems were designed for premium gasoline, then that's what you necessitate to use.Yes it does. you should always put in what gas is recomended for the vehicle. if a car says regular unleaded next put that but it wouldn't matter a whole lot if you put premium contained by it. but with a car that say to use premium then you have to put premium contained by it or risk damaging your engine. the reason for this is that some cars hold a higher compression ratio requiring more octane to keep the gas from preigniting. if you put regular within then it will most likely start knock causing your computer to back the timing sour making your car run like ****.

Good 4x4? Approximate budget of £3000...
In this case, It does. Premium fuel can withstand difficult compression without detonation. a high celebration engine like the one in your sports car will cause lower octane fuel to detonate prior to being ignite by the spark plug, causing the problem known as knock. Sustained knocking can damage the engine.you enjoy to go with the instruction book.

Are hybrids really adjectives that more fuel...

Guy's what do you reflect on is...
The octane rating of gasoline tell you how much the fuel can be compressed before it spontaneously ignites. When gas ignite by compression rather than because of the spark from the spark plug, it causes knock in the engine. Knocking can damage an engine, so it is not something you want to own happening. Lower-octane gas (like "regular" 87-octane gasoline) can handle the smallest amount of compression before igniting. so sport saloon engines have a higher compression ratio as a consequence needing a higher octane stratumYes it does. you should always put in what gas is recomended for the vehicle. if a car says regular unleaded next put that but it wouldn't matter a whole lot if you put premium contained by it. but with a car that say to use premium then you have to put premium contained by it or risk damaging your engine. the reason for this is that some cars hold a higher compression ratio requiring more octane to keep the gas from preigniting. if you put regular within then it will most likely start knock causing your computer to back the timing sour making your car run like ****.
