I know that there are plenty of articles here about E10, but this one is a good read.

from the article above:

The law mandates the oil companies to secure their supply from local sources before importing. But the local suppliers have not been able to keep up with the requirement. The oil companies will have to import their ethanol requirements to comply with the government mandate. That negates one of the objectives of the law which is supposed to increase our level of energy independence and save on foreign exchange.

me:

stupid law

knee jerk reaction to the 2008 oil price spike

meant to reduce reliance on imported crude/products

local ethanol producers couldnt produce enough so oil companies have to buy ethanol from Brazil

so much for reducing reliance on imports

from the article:

Once government mandates that all types of gasoline be blended with 10-percent ethanol, this shortfall will only grow bigger. So, why is government pushing for the 10-percent ethanol mandate? Sino nanaman ang kikita dito? Given the significant price differential between imported and local ethanol, this looks like pure and simple economic rent-seeking by local vested interests working through politicians like Mr. Zubiri whose family is also in the sugar business.

me:

local ethanol producers must be very well-connected

they lobbied the govt to enact a law that created permanent demand (guaranteed buyers) for their product

Is it better or even required that you consume the contents of the tank before refilling considering napapanis yung e10? So if you had a full tank then consumed 3/4 tank in 4 weeks, then you topped off again to full there would be some e10 there that would be breaking down in about 2 weeks time?

Or does adding new E10 somehow revive the old stuff already in the tank?

Adding fresh E10 gasoline just dilutes the spoiled fuel in the tank.

crappy, so its not advisable to fill up? better to just go on a weekly low amount since this will reduce the chance or amount of spoiled gas? They should really have made the spoilage issue clearer when they introduced this stuff.

Are there petrol brands that doesn't contain ethanol? Other than Petron Blaze?

Read the article and it reads that Petron Blaze 100 is PURE gasoline. But I'm still concerned of the 100RON because I think most petrol engines indicates up to 97RON only? Not sure as I don't have the owners manual with me.

well, spoiled gas lowers your fuel economy. So a mix would result in less than optimum fuel economy.

But when did the gasoline spoiled really, after mixing it with ethanol or after the ethanol has evaporated?
Better buy pure gasoline for economy.

But from the viewpoint of taxmen, more tax from evaporated fuel.
The more evaporation the merrier.

Easier said than done. Where can we still buy "pure" gasoline (or gasoline without ethanol). From what I know, the only one left available is Petron Blaze.

mga bros hindi ba talaga safe ang E10 sa mga carb engines? medyo conflicting kasi sinasabi ng mga experts eh, sabi ng iba ok lang, yung iba naman hindi. yung 89 corolla ko walang E10 ang fuel na pinapakarga ko para sigurado pero sa hindi kilalang gasulinahan ako nagpapagas dahil puro may E10 na ang big 3 at ibang independent players.
