What are peoples opinion of Slick 50 or products similar.

 

I have a rattle that sounds like the valves are loose but i have checked them numerous times and are fine,just wondered if something like Slick would quiten it abit???

[KernowCooper]

Not recommended for a classic  mini as it shares its oil with the Gearbox and can cause premature wear in the box if the tappets are adjusted right Slick 50 would have done nothing to reduce the rattle, if the tappets are set to there correct clearance then suspect worn rockers at the rocker to valve pad.

[venkman]

How would you go about checking them? Would you have to take the rockers off and measure with vernier calipers or is it more in depth than that?

 

Would it be a big issue leaving them?

Never put those 'snake oil' additives in a Mini or the gearbox will fail shortly afterwards with no syncromesh left.

Once the damage is done then these products are useless..............I once rebuilt an engone and I used Molislip......and I had no problems when I fired her up for the first time ..................

A good quality oil, like Valvolene Racing 20w50, Millers, Penrite, etc, have all the ingredients needed for a Mini engine & gearbox.

anything that contains PTFE (polytetraflouroethylene) isn't suitable for use in an engine.

 

speak to dupont and ask them what they think of using teflon in an engine.

The tappet faces can also spall, making it impossible to set the clearances.

Thanks for reminding me of the name of the stuff which completely trashed my 998 many years ago. It made the metalling peel off the bearing shells, so the crankshaft looked like a ploughed field. The hydrofluoric acid produced as it decomposed in the engine cleaned the inside of the transmission case to fresher than new condition, but did massive damage elsewhere. After fitting a new engine, the final drive pinion bearing, never disturbed by me, failed. The cage broke up, and caused the final drive to wedge tightly under load. I believe that very dangerous condition was also caused buy the acid etch.

 

The stuff is downright dangerous and should be banned. It was sold at the time as being suitable for engines.

Well i will deffo be leaving that stuff alone thats for sure Thanks!!!!

If you do think that you want some kind of additive, try the Millers Oil web site. They have proper oils for classic cars such as Minis, including combined engine/gearbox, and they have a very good reputation.

[Captain Mainwaring]

If an oil needed an additive - why don't the manufacturers add it as standard?

I agree that the best thing to do is just to buy a proper oil in the first place. There are times when less is more.

ive been using something called MPG extreme in my engines for many years

 

starting using it when lived in AUS in my road car done 100,000 klms with it in

 

no problems, so thought would put in my mini only done 7000 miles

 

with it in no problems tho.

 

the US army used it there vehicles during the Gulf war both

 

engines and gearboxes, certainly quietens engine

 

no Teflon, its thin stuff not like stp

 

its pretty expensive more than the oil

I've got 280K Miles on a V6 Pajero that's only ever had regular oil changes - 

 

Reading the manufacturer's data...I'm not sure I want to try it.

When decomposed by heat is produces hydrochloric acid in the presence of water.

 

MPG EXTreme PLUS™ is designed for conditioning the metal crankshaft, connecting rods, and allied parts of an internal-combustion engine.
