Anyone use this in their RS's? Or is it not needed with modern oil?

 

not needed

 

Nooooo don't do it!
At the best it won't be any benefit, and at worst it'll cause you problems.
Just use a decent oil and change it regularly
Have a search around the web for various horror stories about oil additives in general, including Slick50,

 

Was just wondering really im abit extreme with oil changes as i change

it every 1000 miles and only use silkolene pro-s 10-50

was just curious but surprised in how it may damage your engine

 

I have used it in loads of engines, but not in RS as it is not really of benefit with decent oil
tabetha

 

i use stp oil additive which is the same as the slick 50 stuff every time i do an oil change have done so for past 7 yrs now with no probs at all

 

What oil do you use matey?

Maybe it can cause problems with just certain types of oil if other peeps

have had trouble?

 

the potential issues with slick50 are to do with the suspension of PTFE particles floating round your engine, and where they end up, rather than interaction with the oil.
If you are using Pro-S and changing it with that regularity, you will be getting all the protection the engine needs and more.
Interesting point to consider - If the additives were so beneficial, then the vehicle manufacturers would be endorsing them

 

Great in a 1980 metro nothing else

 

I used it years ago in my mk2 escort and it quietened the engine down no end but i've read that its not good for turbocharged cars, can block the oil galleries?
