I have a W124 230TE with a 140,000 miles on the clock and l plan to do an oil change this weekend. Question is, l would like to add slick 50 to the engine because of the claims it makes, however, looking online, all l can see is negatives, with little positives about the product.
Has anyone here had any good/bad experiences with slick 50?
Is it just a gimmick or does it reduce friction, increase fuel economy and increase BHP?
Your views would be welcome.
