My Acura shop is recommending a fuel system clean for my 07 with 200,000 kms. Supposedly cleans injectors, O2 sensor, catalytic converter etc on the way though. Worthwhile for $200 or snake oil??

 

Snake oil / money grab.

Modern fuel from a top tier gas station has cleaners and detergents in them, which clean the injectors, which means the catalytic converters won't foul

 

Agreed, l'huile de serpent to be sure. If you want to screw with them a bit, ask them to show you in officially published Honda/Acura Service Manuals and Bulletins; when they cannot show you that, if they still insist the work is necessary, tell them to say that in writing, then send it to Acura.

 

Better clean mass flow sensor, that cause big problems in fuel system. I solved everything just do it this .

 

Sorry, not sure what you're talking about, a 1G RDX does not have a "mass flow sensor".

 

Likely referring to the MAF, which plugs into the intake tubing just past the filter box.

 

Nope, no MAF on the RDX.

 

Uh...the RDX absolutely does have a mass airflow (MAF) sensor.

 

Sorry, no, that is a MAP sensor, a very different device.

 

Sorry, it is the MAF. The car also has a MAP sensor, and that measures manifold pressure (Manifold Absolute Pressure sensor). You can't measure manifold pressure from the air box - it isn't pressurized. My pic shows the MAF circled. The MAP sensor is attached to the intake manifold.

Hmmm, I looked up a 2007 and, per the documentation I saw, there was no MAF; I wonder if Honda made a mid-cycle change between then and 2010.

 

I wonder if it was just a place that didn't sell the part or very early documentation that wasn't fully up to date on the 1G part numbers. The sensor parts are the same for all 1G model years.

 

People use seafoam. I've used it in the past and I've gotten better fuel mileage. My car had 189k miles with no issues, people love seafoam it grew on me. Used it in my oil and gas, you can put it in the brake booster line that's for helping cleaning out the intake manifold. I've never done it but my brother has.
I've never had a turbo so I don't know if putting it in the oil would be good since the turbo uses the same oil. I would say if you can put some race fuel in your car and that'll clean everything out when it goes through. But like the top comment says top tier gas really does help and put in a fuel treatment too, even though they have their own detergent in their fuel it doesn't hurt to put a little more.

 

Meh, Seafoam = l'huile de serpent.

 

Top tier gas already has plenty of detergent to keep things nice and clean. The fuel itself keeps the system clean - no need to run additional things through it. In general, if you use high quality fluids and follow the recommended change intervals, you should never need additives to keep your system running right. Goes for gas, oil, coolant, power steering, etc. That said, if spending extra money on those things brings you some peace of mind, you're not likely to hurt anything.

 

See I would only get gas at Shell and sometimes Chevron, but after awhile I would notice a decrease in MPG, I only used 91 octane (highest they offer in AZ). So I would use seafoam and it would increase my MPG, I only needed to use it twice for about 60k miles which isn't bad.
Also I used royal purple for oil and wix oil filter, change every 5-6k miles and never had any leaks or problems. I would use 2/3 can into the gas and the other into the oil. Before oil changes because I noticed that seafoam increased oil consumption and just run the car for a couple hundred miles then do my oil change.
It definitely helped me but like I said I wouldn't put it in the oil of the car has a turbo.

 

Thanks everyone for their input. I use Chevron 94 almost every fill up so should be just fine, Appreciate the responses, now if I could just get around to installing that downpipe......
