fuel are the same(same RON and emission standard like euro 2M or 3) , but they will add in different additive on the petrol
eg: caltex=techron , shell=v-power

iinm ...bhp purchased fuel from singapore company ..which is euro 3 ..meanwhile other are used euro 2M

once awhile..local oil companies will get products from oversea if their refineries unable to meet the local demand but not always.. if a local O&G company get their product direct for singapore...for sure it will subject for import tax , not to mention paying more (exchange rate), extra cost such as off coast oil tankers to send the shipment, storage area and etc yet they sell it at Euro2M price? u think bhp is doing national service or charity ?    O&G companies can sell higher grade products but our gomen not going to pay extra subsidy for it and the retail prices still the same..

u got it half right....last time our crude oil can fetch higher price because due to low sulfur content and we import cheapo crude oils from somewhere else... but now not the case anymore...

how many of u out there know that the world's most cleanest fossil fuel with almost zero sulfur was born in malaysia....

I use Caltex cuci engine...

Other than that, I find BHP to be most favourable.

Same here. Would pump Caltex every once in a while for their Techron cleansing additive. Otherwise it's BHP for their Euro 3 petrol.

In Malaysia the Techron additive can't be bought separately. Only way to get it is pump Caltex petrol

FC-wise both are more or less the same for me.
