Hybridbird said:10W40 Pennzoil. I use it in the Mustang and the Taurus.I've never used anything but Pennzoil,it got me over 200,000 in my 5.0 T-Bird and it never gave up in any of my Turbo Coupes either.I second the motion on the conventional oil.There's been plenty of old school hot rod racers and builders long before my time that never had anything but and they got along just fine so,it's good enough for me. :banana:
