E5 gasoline is in high demand.

The manufacturer recommends that older vehicles use E5 gasoline, and many owners of older gasoline-powered motorcycles are also searching for this type of biofuel. However, E5 gasoline is not yet widely available.

From the beginning of June, unleaded gasoline in Vietnam will have to undergo a blending process to become E10 gasoline for use in gasoline engines nationwide, as stipulated in Article 4 of Circular 50/2025. Simultaneously, E5 gasoline will continue to be blended for use in gasoline engines until December 31, 2030.

E5 gasoline is in high demand.

As mentioned in a previous article by Tri Thức - Znews , E5 gasoline is still sold alongside E10 gasoline, but it's not very common. This type of gasoline is only available at a few specific gas stations.

Speaking to reporters, Mr. Hoang Tu (64 years old) said he is still looking for a place to buy E5 bioethanol fuel for his Honda Citi 100, which he bought more than 30 years ago.

"This is a brand-new, imported vehicle, not distributed through an official dealer, and the owner's manual has been missing for quite some time, so I'm not sure if my Honda Citi is compatible with E10 gasoline," Mr. Hoang Tu explained his reason for buying E5 gasoline.

He said he sought help at a nearby repair shop and was advised to use up the remaining gasoline in the tank, then have the car inspected before refueling with E5 RON 92.

"The mechanic advised me to fill up with E5 RON 92 gasoline because this is a fairly old car. However, I've tried searching at many gas stations near my house and haven't found any that sell this type of gasoline," said Mr. Hoang Tu.

According to the TCCS 06:2026/PLX standard published by Petrolimex , E5 gasoline is defined as unleaded gasoline blended with fuel ethanol at a ratio of 4% to less than 7.5% by volume. This standard states that finished E5 bio-gasoline can have an octane rating ranging from RON 92 to RON 97.

This type of gasoline is recommended for older motorcycles that use carburetors. For example, Yamaha once advised owners of motorcycles with carburetors manufactured before 2017 to use E5 RON 92 gasoline instead of E10 gasoline.

E5 gasoline is still not easy to buy.
