comments, differences? - Techron High Mileage vs Techron Concentrate Plus Complete, Fuel System Cleaners

[jim04g]

Was going to pick up Techron on the BOGO sale, and see online a new (to me) High Mileage Fuel System Cleaner.

Any comments? Just marketing difference?

Detail:
Notoriously useless MSDSs show a change from N,N'-di-sec-butyl-p-phenylenediamine to Trade Secret for the <1% component (so, could be the same). And the main Trade Secret (may be PEA) changed from 20-25% to 10-20% (so, could be no change at 20%).

Quickly scanning the text for the HM, a few things were removed from the Complete's (longer) recommended list - but not explicitly advised-against.

PDS - High Mileage
Recommended for use in:
• Spark ignition engines with gasoline, ethanol and gasoline/ethanol blends
• Gasoline hybrid vehicles
Will not harm catalytic converters and oxygen sensors.
Not recommended for diesel engines.
Not for aviation.

PDS - Complete
Recommended for use in:
• Spark ignition engines with gasoline, ethanol and gasoline/ethanol blends
• Direct injected gasoline engines (DISI)
• Gasoline hybrid vehicles
Suitable for use in:
• Gasoline two-stroke air-cooled engines (motorcycle or chainsaw)
• Gasoline two-stroke water-cooled engines (motorcycle or marine)
• Gasoline four-stroke lawnmower, motorcycle and marine engines
Will not harm catalytic converters and oxygen sensors.
Not recommended for diesel engines.

This comparison chart from Chevron between Techron products may help in your decision. The high mileage is a stronger consontration.

since they want you to use it every 1K miles instead of 3K miles like the Complete...as well as less chance of dissolving varnish and the help for the fuel sensor (unless you need fuel stabilization) I would use Complete over High Mileage...

How does this help DI engines exactly? It says it does. This stuff isn't touching intake valves, so...?

There's exhaust gas recirculation. I suppose it might still have some ability to clean intake valves if it can survive combustion temperatures.

Appreciate the comp-chart link (didn't catch that one at the website), and thanks for the clarifying discussion.

So, does the High Mileage have more PEA than the concentrate?

I saw that the HM had 1 oz to 1,75gal but that doesn't answer my question.
It also says to use it 3x as often as the concentrate.
Thanks,

Last time I checked yes high mileage more pea than complete fuel system from I believe 2023 .

Just wanted to revisit this topic because I'm also curious if HM is better than Concentrate or if you'd stick with/ the Concentrate version? I have a Honda Civic 185k and a Ford Explorer 160k.
Thank you

You mentioned: "as well as less chance of dissolving varnish and the help for the fuel sensor" Could you please elaborate?

It could clean the injectors.

 

[silversport]

I was following the chart provided by Chevron in CharBaby's post above mine... https://www.chevronlubricants.com/c...es-sheet/Techron-Product-Comparison-Chart.pdf
on the chart help with the fuel sensor is checked for the regular Complete and not for the High Mileage...also the recommendation for use is once every 1000 miles for HM and once every 3000 miles for Complete...that leads me to believe that Complete has more cleaner in it per recommended dose...

I coaxed the Chevron TECHRON tribologist to let me know if one of their "proprietary" ingredients was PEA, and he said YES, and that the high mileage TECHRON had more of PEA. HE would not give me the percentage, but at least I got email confirmation that TECHRON's secret was lots of PEA!!!!.

That's never been a secret. Chevron gushes about how they figured out that PEA worked magic as a detergent additives.

thanks for the pdf and info. It would be better to know what percentage PEA is in TECHRON products, however.

Find the SDS and they'll typically have those as a "trade secret". Granted it could be more than just PEA. PEA isn't the only effective detergent additive.

They aren't going to state a specific amount publicly.

All the products can be found on their website, with the PDS links. The PDS links all show a range of PEA concentration, but not specific amounts.
This isn't secret; it's been publicly available ever since these products were released (and occasionally get updated as products change with marketplace changes).

Gumout brand and Techron brand both have a fairly substantial amount of PEA, depending on the specific product sought. One of the Lucas products does as well.

The best info can be found via the PDS for any chemical questions about a product.

I haven't seen this posted, but you can make of it what you will. I'm sure some will have a different opinion about some of these brands.
