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.
