Apologies if this has been shared but just found out sale ongoing at the store. Plenty stocked at least at the shop I was at.

Bad news is that the additive package has been changed and not for the better.

here is the latest detailing changes in Brad Penn and VR1

LN is recommending the newest line of Driven oils, specifically Driven GP-1 20w-50 or 15w-40 for the aircooled cars

I see no change in M1 15w-50 and will continue to use it in my cars.

Interesting.

Not sure why DA Lubrication, after purchasing Brad-Penn, changed the name - perhaps a sale provision? It has been said they started out with the Brad-Penn additive package, but according to Bill's link, that was then. It says the current product (Driven GP-1) is new and improved.

Walmart has it in Quart 2-packs for less - $8.76 - every single day. Free 2 day delivery when you buy $35 worth - which you will for a full oil change.
