Vehicles that require premium gasoline are designed to operate optimally with fuel that has a higher octane rating. Premium gasoline typically has a higher octane rating (typically 91 or 93 octane) compared to regular gasoline (usually 87 octane).
When a vehicle that requires premium gasoline is fueled with regular gasoline, a few things may happen:
Reduced performance: Premium gasoline is formulated to provide better combustion characteristics and prevent knocking or pinging in high-performance engines. When regular gasoline with a lower octane rating is used, it may lead to decreased engine performance. The engine control system may adjust parameters to compensate for the lower octane fuel, resulting in reduced power output and potentially slower acceleration.
Increased engine knock: Regular gasoline's lower octane rating can cause premature ignition of the air-fuel mixture in the engine, leading to engine knock or pinging. Engine knock can cause damage over time and negatively impact engine efficiency and performance.
Potential long-term effects: Consistently using regular gasoline instead of premium gasoline in a vehicle designed for premium fuel may contribute to the buildup of carbon deposits in the engine. Carbon deposits can affect engine performance, fuel economy, and emissions over time.
It's important to note that while using regular gasoline occasionally in a vehicle designed for premium fuel may not immediately cause severe damage, it's generally recommended to follow the manufacturer's guidelines and use the recommended fuel for optimal performance and longevity of your vehicle.
If you have concerns about the cost of using premium gasoline, it's worth considering the potential trade-offs in terms of performance, fuel efficiency, and long-term engine health. Ultimately, using the recommended premium gasoline will help ensure that your operates as intended by the manufacturer.

高里程车使用93号跑2500迈去清洁engine？这里有这样做的吗？
Add only the octane your manual calls for. Top tier gas has the best cleaner, regardless the octane number.
2台完全相同引擎（2GR一FE，但ES要求91号汽油，而SUV仅要87号），ES经常91 + 93; 而SUV则87 + 93。两车16年以来都不见冒蓝烟烧机油，3.5 ～4 K迈换油时也从不怎么缺油，感觉动力依然十足，因此长期使用稍贵的Shell汽油好像有了点pay back。
固然，老车目前还没冇老化到油渍满目、积碳烧油，也不是仅仅因为用了一点V-Power就是灵丹妙药，其它因素包括是自然吸气还是高功率涡轮增压；是勤换全合成机油还是省事省力可不换油尽量不换；是代步工具还是下工地拖重物…
08年老车、17万英里的发动机没清过碳、无大修，只换了一次火花塞，一次水泵：
有所得就有所失。看看那些各式清积碳的方式。有不少乐趣的
至于用什么机油，只要是合格的产品，问题都不大。但尽量不要用过。勤一些换油，是最好保险。那些把合成油用满一年的，甚至完全靠，甚至纠结于车的机油换油提示灯的用户，总是给人如履薄冰的感觉。车都有里程表，换油的时候记一下，差不多里程或时间到了就勤观察一下，到了换油即可。
可能心理作用，觉得 Shell 的#93 V-Power 清洁功能貌似不错。
16年了，最近发动机里面加了德国的Liqui-Moly积碳清洗剂（“力魔”是听头条介绍的，国内迷信舶来品），run 150 miles后换油，据说可以去除活塞环积碳，换出的油是比较黑（但是17万英里以来车子从未冒过蓝烟，因此很难确定效果如何）：
汽油里面加过一次LM的供油系统清洁剂，据说可以清洁气缸上部，喷油嘴，等等地方：
02 Camry v6说如果要performance 就加premium,我用不着那performance,20年18万迈了一直加regular,P事儿没有。
07 Infiniti 说要用premium, 我一直加regular,有一年夏天engine pings, 换了premium也不管用，最后换了传热系数高的火花塞才好了。

打算以后用无醇汽油了。
Not in my cars after 11K and 17K miles. Runs as smooth as silk. All the spark plugs replaced looked perfectly normal.
They called for premium for the reason of selling the car as luxury car. As long as my engine doesn't ping it's perfetly fine.
I don't drive like F1.
另外汽油稳定剂效果有限。
汽油标号是抗震能力，跟清洁能力完全不搭边。
简单来说，高压缩比的气缸需要高标号。Period。
也不存在说高标号的汽油热值高这一说。
