Chevron's PRO-GARD injector cleaner

[F1Crazy]

What are your thoughts on Chevron's PRO_GARD Fuel Injector Cleaner?

I spotted it recently at Costco and bought a pack thinking it's the Techron and since I've never used Chevron products before packaging and price didn't make me check if it's a right stuff. Right now I realize that $2.50 for 16oz. is too low to get Techron but I still plan on using Pro-Gard if it won't interfere with future oil testing.

I tried it twice in two different autos, and noticed a sig improvement in both. I'll use it again. Many people like the much harder to find BG44k or whatever it's called as well.

I prefer Chevron Techron to its Proguard. Techron is more concentrated.

Groucho's got it right- ProGuard _contains_ Techron. Techron _is_ techron.

Can't hurt; techron is highly recommended!

You can compare various formulations at the bottom of each MSDS through this link... Compare to STP as well.
