Chevron Pro Guard Injector Cleaner?

[pabster]

So I was at Costco the other day, saw boxes of Chevron Pro Guard Fuel Injector Cleaner, and bought a box. Before I start pouring, does anyone have an opinion on this stuff? Stuff I've read so far, people seem to think it does what it's supposed to, but I want an opinion from the pros around here...

I used to use chevron techron cleaner for gas and diesels. Works great on my diesels, but I have no experience with pro guard. Most likely a watered down version of techron because of your state (sorry).

I use the Techron concentrate in newer fuel injected cars, usually at the oil change interval. I've actually been able to get fuel gauges to work again in newer cars with in tank fuel pumps by putting two bottles of the Techron concentrate in with about ten gallons of gas. So you know it is working.
Like ws27 says, the Pro-Gard is probably a thinned out version of the same stuff. I would probably use a bottle of the Pro-Gard about every 4-5 tanks of gas depending on what gas you are buying. It's bound to be better than the no-name crap they sell a the dollar store.

I think WS27 nailed it. I did some poking around and found someone had posted a reply allegedly from Chevron (see below).

I also found this on the Chevron site http://www.chevronwithtechron.com/products/fuel-additives.aspx



"Thank you for your inquiry. It has been forwarded to us here at Chevron
Fuels Technical Service.

The ProGard and Techron products contain the same chemical additive.
There is but one grade of the Techron product, while there are four
grades of Pro-Gard. The Pro-Gard products are "Clean-up", "Fuel Injector
Cleaner", "Fuel Injector Plus Intake Valve Cleaner", and "Gas
Treatment".

The ProGard products give lower, less effective concentrations. These
lower-concentration packages often sell for less. They have less "keep
clean" and "cleanup" properties. They are also not concentrated enough
to clean combustion chamber deposits. There are only subtle differences
amongst the Pro-Gard products, mostly having to do with concentration.

Techron Concentrate Fuel System Cleaner is the most concentrated and
will clean combustion chamber deposits. There is approximately 100% more
active ingredient in the Techron Concentrate than the Pro-Gard Fuel
Injector Cleaner. The active ingredient is Poly Ether Amine with a
solvent carrier.

A bottle of Techron Concentrate Fuel System Cleaner, when added to
gasoline according to the label instructions, results in an additive
concentration roughly 10 times stronger than the dose in Chevron
gasolines.

If you always used Chevron gasolines, you should be getting enough of a
dose of Techron such that you should not have to purchase the
Concentrate."
