xado, engine treatment

[Old-Guy]

I share Stickyfinger's scepticism.

When I left school, I went to work for Lister Diesels in the late 60's. All engines were dynamometer tested, and those for particularly demanding applications were run-in, using a moly-based lubricating oil which was drained out before shipping. The efficacy of this expensive stuff had had to be demonstrated by the company's development engineers to both management and to external test authorities like Lloyds and the GPO (Listers supplied the standby generators for all rural and many urban telephone exchanges). The purpose of the Moly was to protect engines, like stand-by generators, going onto full load immediately on starting.

Ever seen a wet-sump diesel engine slowly rotated through 360 around the crankshaft axis, while running at load, with a pause at 180, multiple times? Simulated capsizes of a ship's lifeboat. Impressive demonstration, particularly as external inspectors could, and sometimes did, require an engine to be stripped for their inspection afterwards. Now that's what I call "bullet-proof"!

Here is what happens to the engine without oil:


As you can see it took 7 minutes with medium revs to lock the engine. However with xado or rvs treatment the engine (at least a simple petrol engine. I have not seen a test with disesel or turbodiesel engine) survives driving hundreds of kms without oil. So at least some of their claims are true.

Honda coat the piston rings of their new engines with Molybdenum even today.

Start up grease is not the same as this product, as with this it gets flushed.

Got the car dynoed.
Deeply disappointed:
First pull:
max power=53,5 kw @3650 RPM, Max Torque 171,1 Nm@2800 RPM
Second pull:
max power=54,8 kw@3750 RPM, Max Torque=171 NM@2800 RPM

Those figures are at wheels. Considering the losses are about 10% on the fwd car, the power at the flywheel is about 60 KW.
So in conclusion the product did not help to return the engine power to the standard value.

Altough the result was not like I expected, I still have not lost all the faith in this product. I am going to drive the car 50 km without oil. Lets see how this product works with the diesel engine. If the test is successful, I am going to treat all my other cars with this product too. Specially the gs as it has no possibility to overhaul the crankshaft bearings.
