Auto mechanics share fuel usage tips to help engines last longer.

Recently, issues related to fuel used in automobiles have been a concern for consumers, as some car manufacturers have stated that they will not provide warranty coverage or be held responsible if users do not use the correct type of fuel as recommended by the manufacturer.

Recently, Scotty Kilmer, a veteran auto mechanic with years of experience researching cars since the 1960s, shared his insights on how to use fuel to ensure the longevity of car engines, specifically regarding octane rating.

Simply put, octane rating is a standard measure of fuel performance. The higher the octane rating of a fuel, the greater its compression resistance before combustion. In Vietnam, two types of gasoline are commonly used: RON 92 and RON 95, with octane ratings of 92 and 95 respectively.

Scotty Kilmer advises owners of older gasoline-powered cars to use higher-octane gasoline. Kilmer explains that using higher-octane fuel results in cleaner combustion and prevents carbon buildup.

Using fuels with excessively low octane ratings can lead to carbon buildup inside the engine. Typically, engine internal space is limited, and this buildup of carbon deposits can increase compression pressure. This negatively impacts the lifespan of the engine and its internal components.

Kilmer also noted that in premium fuels with a high octane rating, reactions occur to break down carbon during combustion, which helps to clean carbon deposits inside the engine more effectively. According to him, higher octane fuels result in higher engine compression, better power output, and noticeable fuel economy.

Furthermore, he also argued that using gasoline with excessively low octane ratings could lead to premature engine detonation and damage to engine components.

Furthermore, Scotty Kilmer also argues that the ethanol content is very important when using fuel for car engines. According to this experienced mechanic, avoid using fuel with a very high ethanol content (above 10%). Although a high ethanol content can help reduce emissions, it also reduces the lifespan of metal and rubber parts in the engine system.

In general, Scotty Kilmer's advice to gasoline-powered car owners is to choose high-octane fuel to increase engine performance, prevent carbon buildup, and avoid affecting internal compression pressure. Additionally, prioritizing low-ethanol fuel is recommended to prevent wear and tear on metal and rubber components.

Using the correct fuel for your engine is crucial, affecting engine performance and the durability of its components. Automotive manufacturers now recommend using only the recommended fuel to avoid damage to engine parts. Manufacturers may also unilaterally refuse warranty coverage in such cases.
