WHAT OUR CUSTOMERS SAY

Worth every PENNY. I love this stuff. My recently rejuvenated 2004 Hyundai Elantra GLS 2.0 was having some hesitation issues just off idle, it was beginning to stutter under heavy load at low RPM’s, it didn’t NOT coast very well anymore, and it didn’t make as much power higher in the RPM range (3.5K +) as it used to.

Also, I had recently cleaned and re-oiled my K&N filter (which is outstanding) and re-installed into the factory airbox.

So, I pulled the MAF and used several hits from the CRC MAF cleaner. I observed a slimy grease/oil all over the metal screen and the sensor elements deeper inside the tube. After a few sprays, the sheen was gone. I re-installed and all of the above problems were fixed. In fact, the coasting and low-RPM performance (feels like a LOT more torque) has improved dramatically. Also MPG’s went up (no hard numbers yet, but the needle is definitely moving slower).

So, about the K&N. I have realized that the oil used on the K&N filter media has probably been sucked-up into the MAF and that this oil was the “gunk” that was coating the surfaces of the MAF. So, next time you clean and re-oil your K&N, make sure and clean your MAF about 1k miles afterward with this stuff. Just can’t beat it!

  • 05110: Mass Air Flow Sensor Cleaner – Orlando, FL

Safe cleaning fluid for your Toyota sensor. I paid a little extra for this stuff to be sure I did not damage my $100 sensor. The last time I cleaned my Mass Flow sensor it FAILED about 30k miles later, so this time I am trying this “special cleaner.” Always be careful to “gently” spray your sensor, as I feel a strong stream of any cleaning fluid may shorten the life of the fragile sensor components. You just need to get the build-up off, and nothing more.

Worked for me. I failed e-check because of emissions. The e-check dude told me to go use this stuff and come back. I put it in, drove around town (was a little disappointed that it wasn’t an instantaneous fix) about 50 miles, which is less than the directions called for, IIRC. Stopped by the auto parts store right before the e-check place and had the check engine code removed. Passed e-check. Have used it successfully on a Buick and a Hyundai.

  • 05063: Guaranteed To Pass® Emissions Test Formula – Ale

Passed emissions test without another $300 in repairs. My check engine light had been on for about 8 years. Recently I’ve lived in jurisdictions requiring emissions checks, and a check engine light is an automatic failure. On two separate occasions I’ve taken my car to the shop, gotten $300 worth of repairs and passed the emissions test, only for the check engine light to come back on a couple days later.

This time I poured GTP into a full tank of gas, drove the car until it was at a half tank, and got an oil change where I asked them to reset the check engine light. After driving a couple days with the light off I went to my emissions check and passed, even without cycling through a full tank of gas as instructed in the GTP directions.

The most surprising thing is that this happened over a month ago, and my check engine light still hasn’t come back on. It could just be a coincidence, but this stuff seems to work better than the $600+ worth of repairs I’ve gotten at the shop.

  • 05063: Guaranteed To Pass® Emissions Test Formula

Proved me wrong! Mechanic in a can works!! After 3 years of “paying the smog guy off”, I decided to get my car(2004 Isuzu Axiom) fixed and just pay for whatever needed to be fixed. After investing $3500 into it and STILL NOT PASSING, I was exhausted. I was fighting with the DMV because they would NOT give me a waiver for the year. I was forced to sell my vehicle I love. I went to the ISUZU dealership and they said it would be AT LEAST another $2000, and if the engine wiring harness was not it then it was my computer module. My mechanic said I have one final recommendation for you. He said he doesn’t believe in “mechanic in a can” but try it? It wont hurt as his friend said it worked for him. I put in in my gas tank and the next day went to see him and see if the faulty codes have cleared. He didnt want to promise me anything but he said. I think you’re good? I went to the smog test and PASSED. No joke. This is a lifesaver for me and my 2004 Isuzu Axiom I have redone (bodywork, etc) With CRC G2P I’m able to keep my vehicle that I’ve NEVER had ANY PROBLEMS with other than stupid smog. I WOULD LIKE TO TAKE THIS SMOG TEST (PASS) PAPER TO NEVADA DMV AND SMACK THOSE GUYS IN THE FACE FOR ALL THE TROUBLES.. THANKS CRC!! YOU’RE A LIFESAVER!!

  • 05063: Guaranteed To Pass® Emissions Test Formula

Does what it is supposed to do. This stuff does what it is supposed to do and keeps your brake pads from squealing. While installing the brakes the tip of the bottle makes applying the stuff where you want relatively easy. The tip is like a wood glue bottle with a slot/flat tip for the stuff to come out and be spread around. This will get all over everything if you aren’t a little careful to not get it on your fingers, rags, etc. It isn’t because it is runny, its just bright red and like a grease consistency.

Works great on new brake jobs. Normally, AutoZone and PepBoys and things of that sort screw you with those little packets. This bottle will far outlast the uses I have for it and gives me plenty to work with. It is not runny and it holds up grade. The applicator tip is in a flat ‘|’ shape so as to help with cleaner application. A must have!

Worked well. No squeal after my brake job. Love this stuff. Applied to back of pad and got rid of the squeal.

It works! My new brake pads were squealing like a pig! I waited for them to break in, but no relief was in sight. I applied some Disk Brake Quiet between the pad and the piston and presto – no more noise.
