Anybody put synthetic slick 50 into there scoobs?
If so any problems encountered.

 

i've got slick 50 synthetic in my STi 7, I've always used it since it saved my 16 valve astra engine, top stuff!

 

The argument against Slick 50 is "if it really works, why don't oil manufacturers include similar compounds in their performance lubricants?". The big oil companies spend millions/billions on R&D. I cannot believe that a 3rd party can then come along and add some magical ingredient which dramatically improves their product.

Any modern synthetic will give virtually no engine wear.

 

I've used slick 50 on my previous cars (mineral based oils), and it's had good effects, quiet on start up, smoother running, and cooler running temps.

I agree that synthetics virtually eliminate wear, but every little helps.

The probable reason why oil companies don't add it are: vehicle manufacturers don't want it as it can't be added during the running in period. Also after your 3ys warrentee expires, there's less chance of making more out of you.

 

Don't do it!

 

Adding gunk to the engine doesn't help unless the enginge is on its way out. If there's gaps about the place through worn parts (so knackered astra springs to mind ) the particles in the additive serve to block them. Fine. New engine with very high tolerences - particles will clog things up.
My thoughts are don't use it unless your engine is poo & you're trying to flog the car - it might clear up some of its problems temporarily. But certainly not on a new car and probably not on a modern engine. Think what happens to the oil filter with all the additional partticles! Oooh, look - it's not filtering .
