if Mercedes officially approves Techron as fuel additive, why doesn't Lexus?

My car runs great on straight Chevron Supreme or Costco gas after I add in 2-3 ounces of Red Line SI-1. I've been noticing lately I've been guzzling Shell's new "nitrogen enriched" gas - or maybe because I've been using the AC compressor in tandem with the heater to keep the condensation down.
Both Techron and SI-1 use PEA - polyethylamine based chemistry to keep the injectors and intake path clean. SI-1 is 50% PEA by volume along with stoddard solvent and polyol ester oil as a upper cylinder lubricant. Techron is about 20% or so of PEA with stoddard solvent and xylene as its carrier solvent.

Arco and all the cheapie stations - Costco included use a generic add pack. Not to mention Arco cuts their gas down with more ethanol than is used as an oxygenate - Cali calls for 10-15% ethanol to be added to their fuels.

will that get me more mileage?
Arco claims their gas is as clean as the next for fuel injectors.
and since all the local brands get their gas from the same pipe, the ethanol content should be the same.

My 1991 LS400 has a relatively clean intake tract/injectors. Our beater 1996 Nissan Quest however, since it sees only whatever's cheapest needed a few decarbonizings to be done. Besides, use Arco and you'll keep your dealership/mechanic/quick lube and the BG/MOC man rich.

I guess this is a good alternative for those who can't get to stations that have good detergents?
Why do you want to boost octane...? ![Confused](https://www.clublexus.com/forums/images/smilies/confused.gif)
I feel for you. I have to drive a "long" 10 miles to get to the nearest Shell, but at least there's one I can reasonably get to.

95% of the gas stations carrying its brand meet the Top Tier standards.
Just because BP/Amoco isn't on the list doesn't mean that BP/Amoco gas
is no good. It just means at leats 5%(or more) of the BP/Amoco gas
stations are not actually selling BP/Amoco gas.
For example, there are two gas station near my office, Exxon and Costco.
I recently found out that both stations get gas delivered by the same
gasline truck.

so what do you guys recommend-- how often should i buy an additive to keep my injectors clean?
i have another 7 year old car, and it's eaten only the cheapest 'crappiest' gas, and never had any injector problems.

BP, IMO, is a ripoff. In my area, what few BP stations there are charge about 30-40 cents a gallon more than even other top-tier brands like Chevron and Shell. Sure, BP is good stuff, but I don't see where it is any better than Chevron's Techron or Shell's V-power, both of which are exellent (I use chiefly Shell, and sometimes Chevron).

Its probably Benz and Chevron in Bed. Sounds like BS. If you have been putting in your cars for years with no issues I don't think I would be to concerned
