hi all,just brought my first ever audi s3 225,1.8turbo on a 52 plate and i love it its just done 100,000miles and has full audi dealer history,im wondering if its safe to use/put a bottle of slick 50 into the engine oil.ive read lots of mixed views on the subject,some good,some bad!!basically im wanting to know if it will have any nasty affect on the turbo/bugger it up??
anyone who has some honest views/advice for me id be very thankfull!!
