Mga Bros my experience using my old 99 corolla xe carburated engine.

I gassed up with e10 full tank which will last me 2 weeks or so dati. It was ok at the start but mga halfway to the tank, i experienced medyo mahirap start on a cold engine. Namamatay unless you put your foot on the accelerator

After 1 or 2 mins warmup ok na

also medyo humina ang hatak.

What i can think is that since ethanol is known to absorb water, medyo dumami water content sa tank sa tagal ng e10 duun

So after that i gassed up with unleaded and ok na ulit.

I suggest if your going to use e 10 mga 1 week lang ikarga ninyo sa tanke. Then the absorbtion of water should be negligible. Then maybe alternate fuel to unleaded after a 2 or 3x nag e10 to maybe clean the system
