    LN Engineering puts out an informative series of updates on this topic

    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.
