Auto mechanics share fuel usage tips to help engines last longer
Experienced auto mechanics share their experience in using fuel to increase engine life, avoid damage to machine parts, and costly repairs.
Recently, issues related to fuel used in cars are of concern to users when some car manufacturers provide information that they do not guarantee or take responsibility if users do not use the correct type of fuel as required by the manufacturer.
Recently, a veteran auto mechanic, who has been researching cars since the 1960s, named Scotty Kilmer, shared about how to use fuel to help car engines last over time, related to the octane index.
Simply put, octane rating is a measure of fuel performance. The higher the octane rating of a fuel, the greater its compression resistance before detonation. Currently, Vietnam has two popular types of gasoline, RON 92 and RON 95, with octane ratings of 92 and 95, respectively.
Scotty Kilmer “advises” users of older gasoline-powered cars to use premium gasoline with a higher octane rating. Explaining this, Kilmer points out that using gasoline with a higher octane rating will help the combustion process be cleaner and prevent carbon buildup.
Using fuels with too low an octane rating will cause carbon buildup inside the engine. Normally, the volume space inside the engine is very limited, the accumulation of carbon deposits can increase the compression pressure inside the engine. This affects the life of the engine and internal machine parts.
Kilmer also noted that in premium fuels, high octane ratings will have reactions to decompose carbon during combustion, which also helps clean carbon deposits inside the engine better. According to him, higher octane fuels will help the engine have higher compression, good power as well as achieve visible fuel efficiency.
In addition, he also said that using gasoline with an octane rating that is too low and not guaranteed will lead to premature engine detonation and damage to parts.
Furthermore, Scotty Kilmer also believes that the ethanol index is also very important in the use of fuel for car engines. According to the advice of this "veteran" mechanic, avoid using fuel with an ethanol index that is too high (over 10%). Although the ethanol index can help reduce emissions, it reduces the life of metal and rubber parts in the engine system.
In general, Scotty Kilmer's advice to gasoline engine car users is to choose fuel with a high octane rating to increase engine performance, prevent carbon buildup, and avoid affecting internal compression pressure. In addition, prioritize choosing fuel with a low ethanol rating to avoid wear on metal and rubber parts.
Using the correct fuel for the engine is very important, affecting the engine's performance and the durability of machine parts. Car manufacturers now also recommend that users use the recommended fuel to avoid damage to engine-related parts. The manufacturer can also unilaterally refuse warranty if this happens.
