Icon5 Auto-RX: Good, bad, or indifferent?

Auto-Rx Internal Engine Cleaner

Just curious about this product and if anyone uses it or knows more about it, I'm thinking it wouldn't hurt to run it 1-2 times as my car is both high mileage (180,XXX) and has some leakage.

**Note: as far as I know it is leaking some oil from the distributor and VTEC solenoid which is common and should be simple/cheap to fix.

Re: Auto-RX: Good, bad, or indifferent?

Fix the problem to stop the leaking and I just ran some Lucas Fuel Additive and it helped my car out a lot. It idles much better now and feels nicer to drive. A decent fuel additive wouldn't hurt. I would say try the Lucas product first since it's only five bucks. I haven't had any experience with Auto-RX, but I've had nothing but good experiences with Lucus products.

Hmm, strange that you posted that about Lucas, I just tabbed over from their web site and reading reviews for their products on Amazon...

Use Seafoam instead.

^^^ Seafoam on a high mileage motor is known to cause low compression.

So no go on the Seafoam? I Just picked up a bottle and was gonna put some in the crankcase and let it idle for 10-15 minutes before flushing the oil and installing a new distributor seal and valve cover gasket.

Re: Auto-RX: Good, bad, or indifferent?

What I would do is look up the products online. Seafoam isn't good for high mileage motors.

Here are a few threads on seafoam.

Re: Auto-RX: Good, bad, or indifferent?

Thanks for the links Josh! So from what I'm reading it looks like either A) don't run Seafoam, it will remove the gunk filling the gaps from wear caused by high mileage or B) run Seafoam right before an oil change to make sure the stuff knocked loose isn't being circulated in the engine. I'll do a bit more research!

Re: Auto-RX: Good, bad, or indifferent?

If you're afraid of Seafoam cleaning your engine too well and causing lower compression, I would do the 3-way Seafoam treatment (1/3 in fuel, 1/3 in PCV valve, 1/3 in crankcase). Drive your Prelude for no more than 100 miles with Seafoam in the crankcase. Then do an oil change (don't forget the filter), and with the oil change add Engine Restorer.

Engine Restorer will re-fill the wear grooves that the Seafoam cleaned out. This way you get a clean engine with probably even better compression than you had before.

I've always had excellent results with both of these products.

Ahhh good ideas! I ended up doing 1/2 sipped into the manifold via unplugging the brake booster hose and 1/2 in the fuel tank, seemed to work fine although recently afterwards it started missing real bad and I eventually found it to be the #1 spark plug was way worn out, so I'm not even sure it had anything to do with the Seafoam.

I may try some of that Engine Restorer soon or next oil change though.

Re: Auto-RX: Good, bad, or indifferent?

That's pretty steep for 2 or 3 bottles. Besides the Dozens and Dozens of 3rd party pics... which are funny.

Homepage 4.6 sohc ford engine has A Cam in each head.

Cam


Either the ford owner is a moron, or they are, for not spotting that error, WHICH TO ME IS LIKE PARKING A PRELUDE IN YOUR DRIVE WAY AND FINDING A DUCATI IN THE MORNING.

Just do 3 oil changes (same filter) 1000 miles apart from each other and use Marvel's Mystery Oil in replacement of 1 quart. That'll get rid of some gunk. Then use in gas to keep oil sludge from building up.

Check it:

^^^ I might just try this I've got an oil change coming up soon. Gonna go synthetic this time, it would be nice to get a bunch of gunk out of my motor.

Re: Auto-RX: Good, bad, or indifferent?

I've got a few bottles of Mystery Oil around, maybe every 3rd tank or so to save money!

Here's a good Seafoam guide if anyone's interested, I only did 1 can due to time issues, but it seemed to be fine!
