That's good stuff!

Of course it is specifically talking about the Lucas additive that is supposed to help the oil climb the gears.

The PS Diesel Oil Extender is supposed to replenish the XXX in the oil to make it so you can continue to use it for extended periods of time/miles. But the point is taken that you cannot really tell what it is going to do and may not know you have a problem until it is too late...

Not only that, but it is impossible to peek inside your engine while it's running to see exactly what it's doing.

There may in fact be a perfect oil additive out there. Until I see more tests like the one above, I'm not going to play the guinea pig.

The best oil additive that I have found to clean out an engine is Mobil 1 or Amsoil. Sorry I have yet to see any hard evidence that anything else isn't snake oil with good marketing.

Anyone remember Slick 50?

S*it 50?

There was a ***** 50 demo engine on ebay a while ago. It was a 3.5hp Briggs engine with a clear cover on the back to show that it was running without oil.

From: http://www.repairfaq.org/filipg/AUTO/F_Slick_502.html
"The Infamous "No Oil" Demo
At at least three major motorcycle rallies this past year, we have witnessed live demonstrations put on to demonstrate the effectiveness of certain oil additives. The demonstrators would have a bench-mounted engine which they would fill with oil and a prescribed dose of their "miracle additive." After running the engine for a while they would stop it, drain out the oil and start it up again. Instant magic! The engine would run perfectly well for hours on end, seemingly proving the effectiveness of the additive which had supposedly "coated" the inside of the engine so well it didn't even need the oil to run. In one case, we saw this done with an actual motorcycle, which would be rid den around the parking lot after having its oil drained. A pretty convincing demonstration - until you know the facts.

Since some of these demonstrations were conducted using Briggs and Stratton engines, the Briggs and Stratton Company itself decided to run a similar, but somewhat more scientific, experiment. Taking two brand-new, identical engines straight off their assembly line, they set them up for bench-testing. The only difference was that one had the special additive included with its oil and the other did not. Both were operated for 20 hours before being shut down and having the oil drained from them. Then both were started up again and allowed to run for another 20 straight hours. Neither engine seemed to have any problem performing this "minor miracle."

After the second 20-hour run, both engines were completely torn down and inspected by the company's engineers. What they found was that both engines suffered from scored crankpin bearings, but the engine treated with the additive also suffered from heavy cylinder bore damage that was not evident on the untreated engine.

This points out once again the inherent problem with particulate oil additives: They can cause oil starvation. This is particularly true in the area of piston rings, where there is a critical need for adequate oil flow. In practically all of the reports and studies on oil additives, and particularly those involving suspended solids like PTFE, this has been reported as a major area of engine damage."

PTFE- AKA, Teflon.

I dont know about you guys but i had a very noisy lifter tick. Even reid (dieseldiehard) listened ot my noisy engine.

Already had ELF 5w40 synthetic oil in the engine (a german synthetic oil) and the lifters ticked like crazy. Used rislone with mobil 1 5w40 and the lifter tick was gone! In only 10 minutes after the oil change as well.

Yeah but Power Service products are good stuff!! http://www.powerservice.com/product.asp

I use their DieselKleen cetane booster in every tank - vastly improves performance, pays for itself with better fuel mileage and faster cold starts using just 4-6 oz. per tank. Am thinkin about trying their Slime-X tank cleaner when i get the chance. Especially in Wintertime I'll betcha their oil additive is worthwhile. I will look for this Wally world special, thanks for mentioning it.

Meanwhile it's hilarious to hear the official MB Dealership opinion on additive products. Just for grins ask em about disconnecting the EGR sometime. If they knew the junk I've bypassed and thrown into the woods out of my 240D, those dealership crybabies would call the police and have me arrested.
