    Default Modern Oil for Excelsior Super X

    The Super X manual calls for Valvoline Heavy or Gargoyle/Mobileoil BB in the oil tank. Iíve done some searching in the forum and on the wider internet and havenít yet found any clear recommendations on a modern substitute. Any advice from Super X owners or mechanics would be appreciated. Not really looking for a debate on this brand vs that brand, but recommendations on type and weight; detergent/non-detergent; multi-grade/straight weight; etc. What are people using? If there is an existing thread on the forum that Iíve missed, I apologize, and please point me to it. Thanks!

    Good choice, Likemall!

    'Ashless' is ideal for a "total-loss machine", even if its actually only a tired, tortured, war-horse panhead.

    The dramatic differences in mileage/consumption was proof enough for me.

    I have no explanation.

    I used AeroShell in my total-loss 1928 Ariel on the last Cannonball. I had to install a new guide in Pierre SD, having nothing to do with the oil, so I had the head off there. The piston had no build-up of carbon.

    Asking for a friend sitting on some.
