Checked the reservoir on my 1987 Mercruiser 175 / v6 and the power steering fluid is really low. The only thing my local store had was the pennzoil power tilt and trim fluid. It says on the front "Ideal for: power steering systems" - but I was wanting to make sure this is ok to use? I know there is a specific mercruiser brand power steering fluid also? Should I find and use that instead? Or is it ok to use the Pennzoil fluid?
