Green Oil
 

Just wanted to see maybe opinions on the new green oil by Valvoline & maybe others that now have it. Do you think it is a good choice with the percentage of recycled oil in it. It's a little cheaper, but didn't know if there might be some foreign matter still in it or not? I know it's another oil thread!!
Oh, Well!! Whatever......

It is OK to use in your fuel tank...

Why would anyone ask this question?

Does it have Mercedes approval 229.3 or 229.5 PRINTED ON THE BOTTLE?

If it doesn't, it's not suitable.

NO OTHER DATA printed on a bottle of motor oil means anything.

I just looked at one of my Mobil 1 diesel quarts & I don't see mercedes on it or the numbers you listed. I know lots of people have used it in a Mercedes, however I haven't noticed Mobil on the shelf in Green recycled oil, as of yet. Even if mercedes might endorse something, if there was a failure, I would bet my money they wouldn't offer any assistance. They have a tendency to side-step their own product.

For an older car that doesn't require the latest MB specs its fine, their is nothing wrong with recycled oil, heck its cleaner going back to the refinery than the crap they pump out of the ground.


You have to remember oil base stock never wears out, it just gets contaminated and the additives wear out. If you could install the right filtration system and replenish the additives you would never have to do an oil change. The Navy has been doing this for a very long time, and I suspect other big commercial operators are too.


I saw one MB owner do this with an E300D and he was up to 130k miles on his current fill, 350k total on the engine. He sent a sample to the lab every once in awhile to monitor and it always came back good for continued use. I suspect manufactures don't do this because its expensive to install and people are stuck in there old school 3k mile change ways.

How much oil would we save if they implemented this on passenger cars? Maybe retrofit kits could be made for old vehicles too.

FYI
 

It will never happen.

The recycled mixed oil sludge is run through a high temperature oil refinery/separation/cracking process.

How used motor oil is recycled

Here are just a few issues I see with a built in oil reconditioning/recycling system.

* In mass production the cost per car would be 7-10 million dollars.
* Require constant OSHA/DOE/EPA inspection/licensing.
* Each car would be 13-35 tons (depending on which system is approved) to fit all of the government mandated equipment.
* Each car would require an FBI/homeland security clearance to own/operate.
* Department Of Transportation code will require a CDL license with hazardous material endorsement to drive it.
* Many jurisdictions require this type of equipment to get a permit before every drive and restrict your route.
* Owners would quickly realize the system is a mini refinery, separation, cracking plant = they can and would produce their own fuel (and make large explosions when they screw up the process).

The fines for operating an illegal oil refinery start in the multiple millions, and include instant seizure of all assets.

Its easy to retrofit on an older car, not sure why manufactures don't go that route, since they are all about lowering service requirements these days.

All you need is a good bypass filter, a good synthetic oil, and a lab to monitor it. OTR trucks go 100k miles or more between oil changes doing this.

The setup I saw installed on a 606 was pretty simple, I forget where he tapped off you would need to take a high pressure oil line, and he put the return on the valve cover so the freshly filtered oil was coming back in on the timing chain.

Roy what the heck are you talking about? I'm talking about bypass filters and centrifuge's used on big ships to extend lube oil changes, keep up.

Oops
 

My bad.

Is this what you where talking about?

You have never dealt with bypass filtration? I'm surprised!
