Just after some advise or any experience of Slick 50 High Performance Lubricant/decoke/friction reducer (STUFF) for Imprezas. I just purchased a 98 Turbo Wagon with 83k on the clock. f.s.s.h. I am going to do an oil change just for my own peace of mind, and was going to replace 750ml of Mobil 1 with 750ml of Slick 50 as it recomends in the instructions with slick 50. Does anyone know if this is a good/bad idea. Also the clutch seems to slip when cold, only slightly but there is a fair amount of judder, easily solved by increasing revs. Are the clutches self adjusting or is it on its way out. If so can anyone advise of trustworthy garages in Essex, that can cope with Scoobys. Any help or advise would be appreciated.

 

Clutch judder is totally infamous on imprezas.

Mine is worse when cold and can be cured temporarily with a full bore standing start (but not worth it).

If you can live with it, then I wouldn't let it get to you

 

I wouldn't put slick 50 in my lawnmower !

 

Really, I did buy the version for high performance turbo charged cars. Do u still say no no! Sorry to be inquisitive but why wouldnt u use, even in lawnmower. Mine is high miles 84k so I would have thought some form of de-coke would be a good idea. Do u still say no? Thankx for any advise.

 

Using optimax every now and again should do a decent job of cleaning things, the before and after pics in the recent EVO test seemd quite conclusive re it's cleaning properties

 

I read that Slick50 can slide past the piston rings and also that you can't do things such as crank-grinding once that stuff is used.

Deffo no expert on the subject tho, I'm waiting for John F to reply.

 

There was a huge lot of stuff on the net as to why PTFE based lubricants were totally unsuited to use in engines. Can't find it now unfortunatly.

Only thing I can think of now is if it's so slippery how do they expect it to stick to pistons or bearings....

Oh and if PTFE is 10% as good as Slick 50 and the other b*llsh*t merchants say then why wouldn't Mobil put it in the oil in the first place?

 

jr,Scoobysport in Basildon should be able to cater for all your servicing needs.They sell some sexy aftermarket stuff aswell so watch your wallet!

 

Just put a good fully synthetic oil in your car (Motul 300v 15w50, Mobil 1 15w50 or Castrol RS 10w60 as these seem the most popular) and it will walk all over slick 50 (and as said above, i wouldnt put slick 50 in ANY car of mine!)

hi, i to asked this question a while ago now, and all the answers i got was 'dont use it' and 'it's bad', but no answers as to WHY it was bad to use slick.

Sorry m8

Slick 50 (and other similar products) put flecks of PTFE in their solution. The marketed point of this is that the PTFE cunningly affixes itself to all the parts of your engine that need to be low friction. What actually happens is the stuff sits in a pile in the sump, burning slowly over time, and bunging up the oil filter, making it throw it's little bypass valve open & not filtering the oil any more.
This is not a good thing.
The 'end result' (that they market - not the actual end result!) is produced by a good oil anyway. And these are produced by oil companies who tend to know oil, rather than marketing companies, who know marketing...

 

Well guys thanks for your advise. There goes £25 or 100 miles of fuel. On Sh** that I dont need.Ah well u live and learn.
