I bought a bottle of auto RX and put it in the oil on My truck and I noticed the oil pressure is higher now than it was at idle and running from 60 psi warm now it is 70+psi. Have anyone here used this product? I usually just put Delo400 every 3k miles and that worked out good for Me on other engines but this one I bought used so I thought the cleaning properties of it would help. Any input on this?

Thank You.

 

I used to use additives, until I read this article.

Now I use Rotella T 15w40 or 0w40 full synthetic and NO additives.

 

I read some used this on other engines and thought maybe someone here used it on a 6bt.

 

Why was this moved, My question is specific to 1st gen cummins engines?

 

Don't need to add anything. Use Rotela 15-40 and you'll be fine. I used to change my oil every 3k then sent out a sample to Blackstone labs and they said i can go at least 6k or more on it. There was plenty of life left in the oil.

 

IMHO bob the oil guys lab tests are flawed.

 

How?


I would like to see an actual video and not just pictures.

IMHO all those additives are nothing more than snake oils. Use a good quality, name brand engine oil and you will be fine.

 

Auto RX is a cleaning agent, originally designed for large printing presses, to chemically clean the internals, rather than tearing them apart and physically cleaning the components. It use has just recently been carried over to the automotive market.

I know it's made of all natural materials, namely lanolin based esters. I don't recall how many bottles are added to the oil, but it's possible it has increased the viscosity of the lube oil slightly, hence the higher oil pressure readings.

What's interesting about this stuff, is the actual cleaning does not take place until your next and subsequent oil changes. That's when sludge, varnish and debris that has built up over time will get flushed away and collect in the oil filter. The initial treatment chemically adheres at the molecular level, changing the polarity of the molecules, making them soluble in the new fresh oil as it passes. I have seen before and after pics of heavily sludged valve trains on gas engines, and this stuff works. Compression tests are higher after using it also, having cleaned up the piston rings. All these testaments are posted on bobistheoilguy forums.

I'd rather use this product on a high mileage engine, rather than say, amsoil's 15 minute engine flush, which is mostly kerosene, that thins the oil. A gentle cleaning over several oil change intervals makes more sense than using a radical solvent. Which one sounds more like snake oil?

 

From what I remember last time I looked at bobs site, the tests were at room temp. An accurate lab test will be with the oil at the operating temp of the engine.

Agree on using good oil and changing it regular. But after hundreds of thousands of miles, stuff wears and there's additives that will prolong the life of the equipment and lessen fluid consumption. Part of the additives working proper IMHO is catching the problem early.

Example, had a chevy 6.5 that would use almost a quart of oil every 1,000 miles. With lucas in the oil, that went down to 1 quart every 5,000 miles. Drove the truck for another 200,000 miles and sold it. Kid is still driving it. When i bought my dodge, the power steering pump was leaking, was told it need a rebuild. One bottle of lucas power steering fluid and 5 years later, still going.

Neighbors road tractor was putting in 1 gallon of oil each day, had over 1 million miles on it. With the lucas oil stabilizer, that went to one gallon a week. I'm all for rebuilding equipment when needed, but also for getting the most out of it before I do.

There is some junk additives out there, I ask around and find out what works before I spend my $$. And If doesn't I'll sure be the first to yell foul!

 

Thank You guys, I got even better answers in this other part of the forum (sorry) it does make Me feel better to hear from someone that has used or with knowledge about it. I only put nearly 1.5k miles on this oil and have not used the truck this week but I do feel better that it is not just any snake oil. I usually just put Delo400 and go forward but read some guy liked this one so I bought it and at $23 a pop I do want it to do what it says it does.

Reason I has is partially bc a buddy of mine put it in His th400 tranny bc it was loosing a bit of power (power comes and goes) when going up hill and now it would shift very hard after the fluid so I thought maybe the tranny was toast anyway but don't want the fluid to be the cause.

 

the front crank seal on my truck was getting a little weepy. i added a bottle of lucas heavy duty oil stabilizer and now there isnt even a drop hanging on the seal.

 

I believe oil companys spent 95 times more money on research and engineering than they do on advertising. and I believe additive companys do the reverse.

Which is the reason we moved it for you

 

Auto RX seems to be a more popular cleaning additive that really works. Not sure if it's true or a bunch of hype from Bob is the Oil Guy (you can promote anything on a forum). However, I still wouldn't use it in my truck. Simply because I don't think it's necessary.
