Re: Anybody using Royal Purple in there v6 engines??
So? that doesn't mean its as good as before - it can meet the specs and still be inferior to other products - my guess is that Pennzoil came up with a better incentive for Chrysler, Jiffy lube and my local garage
FWIW my 2001 has had nothing but M1 in it since the initial change after the factory fill at 2k miles... The last one I had to get Pennzoil as my garage had switched and didn't have time to screw around with it.... So far so good...
