Hello,I have a 2003 ford Taurus with 110K on it.Still looks new, and I have been religeious on the oil changes.Is putting in slick 50 a good or bad idea?
BAAAAADDDD Idea!!! don't waste your money.
I have used prolong and slick 50 and have seen no harming effects from using it, they actually increased my RPM at idle almost 200 RPM by lubricating the engine better and my gas mileage increased a little also.
They are a bad idea and have been proven to be frauds those so called additive do nothing at all for your engine. Just stick with a good name brand high mileage oil and you will be fine, dont waste your money on junk.
