Well, at the risk of starting up another Thread That Wouldn't Die,
we in AZ are in the process of losing all our leaded pumps. It
won't be illegal until Jan 1 but the major companies are converting
their leaded pumps to that new middle octane unleaded even now.
With specific respect to Triumph 6-cylinder engines (in my case
a Vitesse, head equivalent to a Mk I GT6) has anybody experienced
valve recession problems when going over to unleaded?
I've started her on premium unleaded with a wee dram of Marvel's
Mystery Oil (tee-em) in the hope that this will help provide the
missing lubrication. Do I have much to worry about? How is
Triumph steel at handling unleaded?
