The “best mechanic in Spain” says that Low Cost gasoline is of worse quality than the premium. Reality is much more complex

In the long term, fuel Low Cost “It can cause breakdowns.” We do not say it, says Carlos Pérez, recognized as “best mechanic in Spain” in an interview with Canal Moveo de The avant -garde. And we don’t give it because, simply, there is no reasons to say it. In fact, Carlos Pérez himself emphasizes that “all gasoline ultimately come from the same wholesale suppliers.” So what happens?

Who. As we say, one of the spaces that The avant -garde He dedicates to the mobility sector has interviewed Carlos Pérez, known on the Internet as “the best mechanic in Spain.” The title is no invention, among the different awards he has obtained we find the one delivered by The workshop community who are focused on communication within the post -sales market.

Since then, Pérez has granted various interviews to different media in which he has been explained about What are the most reliable brandswhat are they the car models that recommend Or, simply, which is the best gasoline to use.

Yes, but. And here comes the controversy. In his statements about gasoline to use, Carlos Pérez assured the following to The avant -garde:

“Although all gasoline ultimately come from the same wholesale suppliers, the differences are in the additives that each company incorporates. These additives are those that help to keep the feeding system clean and prevent the accumulation of waste in the engine, which can affect the performance and durability of the vehicle. The price can be tempting, but in the long term, the use of fuel That supposes in repairs “

That is, a Yes, but in full rule. According to Pérez, there should be no reason to distrust the cheapest fuels but in the long run “it can cause breakdowns and greater engine wear.” Obviously, the price would not compensate for the expense and headaches of the breakdowns.

Same origin. The truth is that in Spain there should be no differences between refuel Low Cost or supposed fuel Premium. Because deep down, the fuel is exactly the same.

And this is not much less. In Xataka We already played this topic in 2015. Then we explained that the origin of both fuels is the same: CLH or hydrocarbon logistics company that In 2021 he changed his name to exolum. This receives the fuel from the refineries that are distributed by Spain in the hands of BP, Cepsa Moeve or repsol. This fuel already arrives with quality standards that guarantee a good product.

This fuel is maintained in the exolum facilities until it is distributed by the service stations. It is here where the difference between products occurs: additives yes or additives no.

The additives. To begin with, the exolum itself already has His own additives (HQ300) For part of the fuel it stores. It is the responsibility of the Marketing in charge of fuel with additives or without them. Obviously, this second is cheaper.

What is an additive thinking? In theoryto improve long -term engine and vehicle care. Companies Premium Do you sell that their formulas manage to leave less remains in the engines or allow more kilometers with the same amount of fuel.

And is there scientific evidence? Really, none. At least that is what Carles Fité, Professor of Chemical Engineering, and Rodrigo Soto, chemical engineering reader, who asked about this same matter, pointed out that “all are equal. I see no difference at this level of analysis.” According to their samples, “they basically contain the same compounds and in the same proportions. Everything comes out very very the same”, in words collected by The confidential.

Nor have they found substantial differences in the OCU. In fact, they point out that we are talking more about blind confidence in the effects of additives than on realistic checks: “The effects of additives on engines and gasoline consumption do not seem very verifiable. (…) Prove that an additive lengthens engine life is very difficult, because there is no way to determine how much that same engine would have lasted if that gasoline had not used.”

And the secret? The secret is called the economy of scale. Simply, there are two types of business when we talk about service stations. The gas stations Low Cost They can save the customer money because they themselves They already save money on operational costs Of their businesses: they do not usually have employees, they do not invest in R&D to improve those fuels and do not invest in advertising, trusting in the mouth-oreja.

On the contrary, gasoline stations Premium They base their business on those additives that generate confidence in the client. But also In formulas to catch you in the following purchase such as loyalty cards or stores that orbit around the suppliers. Also in their Agreements with other companies as insurance companies or large supermarkets.

Scams and maintenance. In summary, the quality of the repossed product has much more to do with the maintenance of the service station (which is renewed regularly and does not spend too much time in deposits, for example) and, above all, with complying with the minimum quality standards.

The latter should be an endorsement when we repost in Spanish gas stations, however, in recent months the SERVICE STATION SHOWS They have used worse quality fuel and took advantage of great sales at very low prices to subsequently scam the State in the presentation of the VAT tax. This has generated a worse image to the product Low Cost.
