What is the general consensus about the best additive to help clean an older sludged engine? I am helping someone clean an older pushrod V8 with a carburetor that has a some sludge due to lack of use and a very slight lifter noise.

Would Auto RX be a good choice? Or maybe something solvent based? Maybe just run a HDEO? Obviously being an old engine I wouldn't want to damage any seals either.

Any opinions?

With the engine still in one piece and in the car, add 1qt of diesel to the sump, idle for 10 mins, replace filter, repeat. (As many times as necessary till the fluid stays clean.

If the engine is out/stripped then brake cleaner, pressure washer, autoclave, bucket full of nasty solvents etc..

No need for additives. Many oils now contain plenty of cleaning agents. Try Maxlife or PP.

I personally would not use diesel, or any other harsh solvent. I have (In the distant past, which seems to be where your project comes from) had good luck using Rislone to turn sludge into a drainable liquid, and also to work some magic on noisy lifters. You could use it with an HDEO, maybe a couple of short OCIs.

Why not try a product designed to help engines that are older and/or neglected: a high-mileage oil like Mobil1 HM or Valvoline MaxLife? Mobil is confident enough in M1 HM's cleaning abilities to say the first few OCIs should be short (3-5k) to deal with the crud the oil is dissolving.

There are lots of opinions here, but one is that cleaning that is done too rapidly via introduction of a solvent can do more harm than good as sludge and whatnot is displaced too quickly, clogging filters, oil pickup screens, valve lifters, oil feed lines, etc. I'd try the HM route and see if it worked before resorting to more drastic measures.

I agree here; a too rapid cleaning can lead to blockage.

I have used ARX and it works as advertised, cleaning gradually over 1500 miles, so that would be how I went about it.

Using a known cleaning oil after a couple of ARX treatments would complete the job.

Any pictures of how much sludge?.
I strongly urge you to look through old threads on this ARX product especially the ones about posters being paid to promote this stuff.
After spending a lot of money on this product with zero results i would not buy another bottle or recommend it to anyone.

Look up some of my Honda engine cleaning threads about cleaning an engine. There are a few ways to do it and a few chemicals that may work better than others but there is nothing that is a one size fits all.

+1 - MaxLife red bottle is all you need. A couple of 3000 mile OCI and then maintain normally. Avoid all special cleaning additives.

FWIW I have received nothing from ARX except their product, at my expense.

Perhaps your engine was too clean to benefit! I have used ARX on at least 3 used vehicles I purchased, and each time it worked as advertised.

Now that I agree with 100%! smile

So, who are the posters paid to promote it?

Only one I know of, who has no credibility given his multiple impersonations.

As for old postings. I have several that praise it over and over. Even one post that declares it miraculous.

I am an Auto RX client. I bought more than one, my own fault, I know.

When I inquired about a refund I was ridiculed both by email and online. A truly non friendly company and a product that we were unable to eke out even the tiniest benefit out of.

All this hoo ha about rapid cleaning is just that, baloney. I have used Kreen in about a dozen vehicles with fantastic results in all but one. The stuff works.

And the company backs it up with a no-quibble guarantee that they actually honor...

Some people have had good luck with autorx (like myself), others not. I believe there is a thread from dnewton where he got before and after compression readings and it certainly improved the #s.

I've taken aspirin to relieve a headache and it hasn't worked; that certainly doesn't disqualify it as a pain reliever when others ask for a recommendation.
