Driven Racing Oil:

[Captain D]

Just curious to ask please:

I'm thinking about trying out the Driven Racing Oil. I realize that factory for a 69' Charger (383, Base Charger) called for 10w-30, and here in PA it's probably a good weight, but synthetic blend or conventional?

Like any (older) vehicle, yeah there's some minor seepage around the oil pan (minor),but with that being said would conventional be best? I've used 10w-40 Brad Penn / Penn Grade1 synthetic for a lot of years, but the oil pressure could have / should have  been higher. Any thoughts?

Thank you,
