Is there a government agency that checks the quality of fuel at gas stations? Are octane ratings checked?

Then why the need to attach videos of Shell V power self-serving advertisements if you don't believe them?

Also, higher octane does not relate to power or more heat energy by the fuel.

I posted them because it`s true that it can really clean the engine I myself can vouch on that

it`s not just V-power, even caltex higher octane fuel, I just posted them because they have the perfect presentation on the cleaning process of the engine...

higher octane does not relate to power or more heat energy by the fuel.

Ohh really? then I guess it`s time for you to restudy updated mechanical engineering not the 1980`s ME on the philippines

Just my observation:
When I first had my car, I just used the Fuel Save from Shell. It used to have a 93 octane rating. Then last year or 2 years ago I guess, it changed to 91. I noticed a decrease in power, so I shifted to Nitro+ with a 95 octane rating. There was an increase in power, but somehow the engine is not that silent compared to using a 91 or 93 RON. So I shifted back to 91 hehe
Below are the average mileage I got using different types of unleaded gasoline in Shell (I haven't tried other brands for my car)
Car: Vios A/T
Shell Fuel Save (93 RON) - 12.5 km/L
Shell Fuel Save (91 RON) - 10.5 ~ 11 km/L
Shell Nitro+ (95 RON) - 12 km/L

I think the reason why some have a low mileage when using gasoline with higher octane rating is because they love to race(figuratively) already hehehe

As for the topic, I'm not sure if the government checks the fuels of each gasoline station when they renew their business permit, or something like that. Read some complaints online that there are some stations(not sure here in Cebu) that have contaminated fuels.

Thanks chibi for the average mileage. It is very similar to my friend's actual experience of 12+km/L for 95 octane rating and only 11+km/L for 93 octane rating.

I have posted other actual observations on my 1st post (updated).

bro diesel fuel itself is a hygroscopic fuel, it tends to absorb moisture naturally, by and by magtubig gyud na ang tank reservoirs sa gas stations, naa nay mga special moisture filtering devices ang fuel pump mismo sa mga gas stations, supposed to be every quarter na sila dapat mag ilis kay mutubig gyud na ang diesel, for some reasons dili maka ilis ang ubang gas stations on time mao nang mapunta sa mga end users maglumba ug check engine ang mga CRDI nga mga sakyanan, ang uban gyud mga stuck-up ang mga injectors, so dapat unta ang mga gasolinahan dili mag tipid2x ug ilis ug moisture absorber filters kay di lalim kung mga stuck-up na ang mga injectors pirti gyung mahala....

ikaw na gyud koya haha after nakog swap engine, ako ipa mods nimo ako auto boss ha. pareha sa imo sx8 para tipid. hehe
