No

Would you add vegetable oil?

 

my 85 passat engine started with blue smoke a few thousand miles after using this product

 

see http://neptune.spacebears.com/cars/legal/s50com.html for the FTC's considered opinion.

 

Stick to the manufacturers recomendation or pay the price...

But I have done in the past! and I am debating about doing it now! a friend of mine has added Wynn's? hydraulic tappet fluid? to his VR6! it appears to have quietened the top end rattle it had

his top end was a little noisy on start up! till the tappets had fully pumped up? but now the rattle is gone! it seems the fluid aids tappet pump up pressure? or something? :(

Sawdust has a similar effect in gearboxes.

I have used Slick 50 in all of my cars with no problems and i am fairly convinced it makes the the engime quieter. I have never had a problem.

 

Isn't Castrol GXT magnatec basically oil with Slick 50 ( type stuff) already in it .

 

Slick 50 must have sold billions of litres of the stuff, it cannot be bad surely.

Not required nor advised - use branded oil and filters and change when scheduled.

Just because a product has been sold in great numbers is not proof of quality or reliability,and should not be judged to be so. The main purpose of Advertising is to make us want and buy a product. Slick 50 is an uneccessary item to add to a perfectly servicable engine or gearbox and many similar products are created to make us believe they will improve are lives .....This is not so !!

 

Example

If you fit a fuel saving device to a car it will usually give you a better return on your fuel consumtion ........ because you will be driving more economically making the fuel saving device seem to work. Justifing to wasted outlay in the first place so i suppose ironically they do save you money!!

I doubt that Slick 50 sells in any great quantity, its a 1980's product (and thats where it should stay). High profit for the local Motor discount shop. Sorry, but this product appeals to the weak minded and boy racers who want to squeeze another 1 mph out of their Corsa.

 

Slick 50 sales figures are about as reliable as their claims. PTFE based products are known to block oil galerys (the PTFE never stays in suspension)

 

Magnatec (also a highly contentious product with claims banned by the FTC in the USA) does not use PTFE or similar additive, but works on supposed molecular properties disputed by many.

 

All engine oil sticks.

 

I do however recall that guy who ran his car on seawater...... :(

 

Take a look at the very specific VAG instructions on oil in cars using variable interval servicing (i.e. VW503.00/petrol VW506.01/diesel) if the correct spec oil is not available.

 

"In exceptional cases, you must top up only once with Specification VW502.00 (only for petrol engines) or Specification VW 505.01 (only for diesel engines) to maximum 0.5 litres. You must not use other engine oils - risk of engine damage!"

 

So even a small variation from their spec gives them cause for concern.

 

Quieter engines/tappets are simply the results of thicker grade oil - a trick also used to reduce oil consumption (in the short term). Fiat sells a good special MILSPEC oil for this available from dealers - testament to Fiat engines and used in battlefield tanks.

 

More usually, quieter engines are all in the mind - the feel good factor.

 

I've never, in 33 years of motoring and messing with all type of engines, ever seen an additive do what it says on the can inc Redex (only exception is radiator sealer). The longest engine lives I've seen is using standard Manufacturer spec oils only.

 

Of course if you sell the car when its only got 50k on the clock it makes no difference - except your pocket will be lighter.

 

 

....end rant......

I agree with Seatkid - the oil companies spend a fortune on R&D to get the blend of additives etc just right, so to mess around by adding other "stuff" is highly inadvisable.

Hi All

The addative debate cropped up in a previous thread a few months ago and as I said in that one, an engineer told me years ago DON' PUT ADDITIVES IN OIL IT UPSETS THE BALANCE OF THE OIL, :( buy a good quality oil and filter (as stated earlier by SA Intruder) and stick at least to the recomended oil change intervals or if on lots of short runs change sooner. :rolleyes:
