I'd stick with the techron, it's what I use and seems to be among the best of the fuel system cleaners.

Redline SI-1 would be my choice, though the BOGO deals on Techron make it pretty tough to beat.

for ported FI types of fuel injectors (configuration), the only proven type of FI cleaner is PEA (polyetheramines). In chevron's brand, it's techron; in Shell's vague terminology, it's their nitrogen-enhanced additive.

Redline also has PEA based FI cleaner available.

I typically chose to do FI (in the form of fuel-additive in a full tank of gas) right before an oil change, not right after (don't want the cylinder washoffs to contaminate the motor oil in my crankcase).

I also don't believe in those "jack of all trades" type additives, for they are not proven to possess cleaning ability for injectors (ported type).

As for DI type of engines, dunno how effective PEA works and I have a strong believe that the chemists and scientists are actively working on a new additive for DI gasoline engines.

Port injection is called so because the fuel is injected into the intake port, upstream of the intake valves. Cleaners work well here because they clean the injector nozzle AND the intake valves, since the fuel/air/cleaner mixture "washes" over the intake valves as it is being sucked (or blown in a super-charged application) into the engine.

Direct injection is called so because fuel is injected directly into the cylinder. The issue with this, at least early on, has been that recirculated PCV moisture and oil vapor builds up on the intake valves, since no fuel washes over the valves to keep them clean; thusly, adding a cleaner would have no affect.

I honestly don't know how cleaners affect variable-valve-timing-type EGR systems, but I wouldn't bet on a cleaner maintaining my valves clean in a DI application.

IMO, use FI cleaner when ever. I don't see any benefit to waiting until just before an oil change, since most people don't have too much fuel dilution, let alone cylinder washoff. Also, would fuel injector cleaners cause faster degradation of the oil than regular fuel?

Agree.

Has anyone verified that the HM & AIO Gumout products really do have PEA in a good quantity?

According to these 2 links yes, but they don't say how much.
http://www.gumoutprojectmotorhead.com/?p=606
http://www.scca.com/about/?cid=50879

The All-In-One has the "best benefits", with 3 checks for one tank cleanup. Does that mean the most potency? Who knows.

I recently gave the HM one the smell test, and it stunk of fish to high heaven, for what that's worth. I believe that is the odour of PEA.

Q.


Is there documentation to substantiate this? I've never seen anything about Shell having PEA in their fuel.

Yep I think it is as high as 60%!

Have you found a brick and mortar parts store that actually carries this product ???

The only place I have found it is on the internet.

I got it off of amazon a while ago, when it was cheaper. I only ever saw it online. I saw the weaker formula at local NAPA, which is the one they sell in the DIY kit.
