Note: Gumout FIC comes in several "flavors". You want the more expensive stuff that says REGANE on it as it contains the key cleaning ingredient poly-ether-amine (PEA). The cheaper stuff doesn't work near as well.

Redline Si-1 is my product of choice. Significant levels of PEA and easily obtainable.

Yes. I got it the first time. I bought the regane high mileage gumout because I needed something right away and that is what the auto store had. It made a noticeable difference after only about 125 miles. I'll check for the redline Si-1 next time I'm there.

OK. Glad to hear you did pick the right one and had a positive experience. On BITOG, Regane is well known and respected. I mix it into the mower gas and pick up a few bottles whenever I see it on sale. The HM version contains higher levels of other detergents good for older cars.

Pep Boys & O'Reillys carries Redline. Not sure about Advance or Auto Zone. I think it's a cut above Regane HM. Still reasonable though at around $10/bottle.

BG-44k is now around $25/can! That's just nuts...........Nearly doubled in price since I began using it decades ago. A bit rich for my blood now.
