1989 300te After a few years now of owning this car, I got the glovebox manual. It says engine oil should be 20-50 for my temp range (New York). I have been using 10-30 Mobil One. Should I change? Do synthetic #'s mate with Dino #'s?
My mechanic uses ATF in the steering pump/ rear hydrolic suspension. My Steering pump fluid is low right now...what do I top up with? They suggest an MB product...Any thoughts?
I have to do a brake fluid flush...Can I just use my good ole Castrol brake fluid?
Thanks.
