1 Quart of Redline to clean your engine?

[PT1]

Since Redline oils are group V esters has anyone tried adding 1 quart of redline to their dino to "clean" the engine? Did it work or am I crazy? One of the guys at work says that is the best way to clean an engine. I think he is hosing me so to speak.

The best, and safest way to clean an engine, is Auto-RX.

As I posted in the past--motor oil is supposed to maintain it's own cleanliness and not to "clean" others.Because of that, adding a qt of Redline isn't going to help at all.

I agree with ToyotaNSaturn that AutoRx works well in "cleaning".

Supposedly ester will have a cleaning effect. I am thinking that a higher concentration may be better, like 2 quarts, but best would be a whole load of Redline.

 

[Gilitar]

Why not just add a little MMO? Maybe 8 oz or so.

 

[Doc8404]

why not just try a cycle of ARX?

When posting this I already knew I was going to get pelted by the autorx "Moonies". My question is about adding a quart of redline to dino because of the cleaning effects of ester based group V oil. The reason being 2 qts of Redline is 1/2 the price of a bottle of autorx. The fact that group V oil wil have scrubbing effect on engine internals is already proven whether you believe you claim to know what it is "supposed" to do or not.

So why not go with a full sump of Redline instead of 1 quart? It should be ~5 times more effective...correct?

I would think so but I just want something that will lightly clean. I have read lots of bad reports by guys who switch to 100% redline in a vehicle with 100k of conventional. They get leaks. Most recommend weaning the motor off conventional 1-2 qts at a time.

Sometimes you have to pay more for the proper cleaning. Auto-Rx works! Anything else is just a guessing game. I would venture to say that if one or two quarts of Redline did work, there would be some success reports here.

I've never read any engine-cleaning news on Redline here. I've been channeling oil-related threads here almost everyday now for the past three years.

If you want it done right, then dig deeper in your wallet.

I have added a bottle of RedLine many times for that reason. It adds moly, is a better lubricant and if it does a bit of cleaning along the way..what the hey.

You'll have to search but there are posts where people have tried to use a quart (or a full charge) of Redline in hopes of cleaning and have had essentially no result. Perhaps if used continuously for a long period of time it might have some effect. But as pointed out, it is not designed or formulated to be a cleaner.

At the same time, there are people who have used ARX (which *is* designed to clean) and have had little or no cleaning results, while others have had phenomenal results.

1: perform full ARX treatment with a PAO synthetic and 1 quart of RL.

2: perform rinse phase with mobilclean 5000 and 1 quart or RL and a maintainece dose of ARX.

3: repeat steps 1 and 2 until engine has reached desired cleanliness level.

4: dont let the engine get sludged again by switching to a better oil than you had originally.

Personally, I prefer borscht.

Well, i'm trying some "snake oils" before I buy auto-rx.
We will see if I will be ordering some when I cut the filter open.

 

[BillionPa]

just dont let those snake oils damage the engine with their snakiness.

 

[sprintman]

If you think a quart of Redline will clean your engine you are sorely mistake. Our Outback ran Mobil Delvac 1 and Redline 5W30 for quite some time. They are known for keeping an engine reasonably clean. Then I RX'd it. Should have seen that oil and filter.

How can you say that? I have not seen this information. Proof please?

I9said "supposedly" because I have no proof, nor know of any proof, but I believe some of the experts here will agree and that the folks at Redline would also agree. I think you will need a whole crankcase full to really do any cleaning and then maybe more than one OCI. I just ran a full load of Redline in the Aerostar for 7000 miles (15 months). Will see if the blotters look any cleaner now that I am off the Redline. Not exactly proof but would be suggestive.

I just saw a post where Bruce381 said that a calcium containing additive will do some cleaning ("Calcium, in oil", in the Additives forum):

So if I bought a calcium based detergent that claims to clean all engine parts, it is actually removing and suspending sludge? Am I right?

---

To some degree, CA sulfonate is used in Industrial rust inhibiting oils and will also nutralize acids and help to suspend and clean sludge/varnish in a PCMO.

I believe an oil like Maxlife can clean your engine because it has extra calcium and whatever other cleaning agents Valvoline folks put into it. I do think Maxlife is going to take a long time, many OCIs, but unless the engine is badly sludged and a threat to chocking its own oil lines with crud, I don't see a need to hurry to clean it.

If you think one qt of redline will clean your engine - its not dirty.
