Style chooser

Went to ENEOS today.

The reason I went there is to purchase Tufoil after reading about so many good point about the tufoil.

Searching around in ENEOS about 10 min for the Tufoil and finally manage to find.

Beside Tufoil, there are so many engine treatment and 1 of them is X1R. The TV ad next to the X1R engine treatment keep on playing the ad for X1R, I wonder whether it really can perform as what they claim?

How about compared with Tufoil? Which 1 is better?

I end up walk out ENEOS...
