Has anyone got any comments about using Slick 50 or other Oil additive in petrol/diesel engines, also in manual gearboxes.I know many years ago a lot of people sweared by them but do they really work or is it all hype.
Thanks in advance

Matter of choice i suppose ,I think they are ok. Had an International T2670 semi 1980s and used Wynns in the gearbox and diff, 1,130,000ks i did and both were in it when i sold it.My Landcruiser G/box just just expired at 638,000ks with Nulon and or Wynns ,fonr diff can't coubt , it not used much but rear Diff was checked recently at 625,000 when i had a locker put in and they said crown wheel/pinion was fine.Now i guess it's up to you...it's your car.

We had a series of planetaries that were failing in our line of work and we tried nulon, wynns, pro ma, slick 50. Whilst they definently extended the life of the planetary gears and bearings by nearly double and cooled the oil from 130c back to 90c we found that
Mobil Synthetic gear oils increased 10 fold + the life of these problem planetaries. But synthetic oil is fairly xxy.

I do not believe these products are worth the money. As the previous post said you are much better off with a quality oil.
Whilst most of these products will do what they say they do, many have harmful side affects also, such as reduced oil flow, seal and o-ring damage. My H/d Mechanical TAFE lecturer also worked for CAMS and did a lot of testing of these products and did not like them.
With regards to a diesel engine I would be very cautious about additives. The last thing you want is to glaze the bores.
I am in 2 minds about teflon type products. See how easy it is to scape the teflon from your frypan, then image that in you
bore. Having said that, I added some to an old GS1000S motorcycle engine years ago and it seemed to bring the compresion up quite a bit (a much reduced overrun time in neutral).
I would only use these products as a last resort.

"use them as a last resort"
Google will bring up lots of hits if you use the search "Snake oil lubricant additives"
like this....

I definitely wouldn't put them in any motorcycle with a wet clutch.

Like my old grandfather say’s, if the oil companies wanted the stuff in there oil they would of put it when they produced it.
Spent his working life working for
Mobil, GM Holden and Honda.

Its OK to use Teflon based products in a motorcycle with a wet clucth PROVIDING the oil DOES NOT contain friction modifiers.
