Has anyone seen this stuff work eg Morey's, Lucas, Nulon, STP etc etc etc. I personally think they are crap espicially when Shell, Mobil, Motul spend millions in R&D.

While I realise it is set up to sell the product...........

Morley's (I think) has a display (saw it at Supercheap) where you turn the handle and plastic gears turn in oil and oil with Morley's added.

The difference is very graphic, the oil behaves as you would expect, but the one with the additive clings to every surface and lingers in the gears.

The little plastic cogs are a long way from your gearbox in the middle of the desert in 45 degree heat.
Someone,and I think it was an engineer, wrote that you dont need a big globs covering the gears and bearings.
Just a film between moving parts and after all,there is only room for that and the centrifical force fom the spinning gears would throw the excess off.
Others claim that the additives or thickeners combine with the sludge and block up the channels that supply oil to various parts in an engine.

The Sceptics society have added the Slick 50 range to their lists of products they believe run on myths. Anyone used it?

I used Slick 50 in my old MG many years ago, despite all the promises of 50% extra power due to increased slippyness I didn't notice a difference I could honestly say wow, BUT I did say wow everytime I changed the oil and added Slick 50 again, cost was nearly more than the oil & filter. Personally I stick to a good quality oil and a genuine filter up front spending a little extra there rather than buying a cheap oil to compensate for the expensive additive, seems to work for me.

Yep that is for sure it's funny that Slick 50 is owned by Penzzoil Quacker State ( oil manufactoring ) and in turn they are owned by Royal Dutch ( Shell ). I personally believe that if the like's of Shell, Mobil, Motul and Castrol found better additive package's they would use them..

Until I see some hard and fast facts and proof they work I'll stick just the products suppyled by companys in the know eg Shell Mobil otul etc etc etc etc

Hi Rossco
I'm with you
If the oil companies could get more of our cash by proving that the additives are needed they would.
plus, if a car msanufacturer thought their product needed a pacticular additive they would tell you and sell it.

I think you better off keeping your oil changes on schedule rather than using additives. Also, you are better off doing improvements to filtration and oil cooling.

Here's some interesting reality reading on the effects of heat on oils in 4WD's.

Part 1 and Part 2.
