91 minimum octane. 93?
no ethanol gas or add Lucas ethanol additive?
Add lead to gas?

In the 73 that my dad and I have, before we had the engine updated to handle unleaded fuel properly, we typically used midgrade with a lead additive. That seemed to give us the least problems with our engine, but your mileage may vary. Most stations now have ethanol in their gas, so it is nearly impossible to avoid. I would suspect that you would be fine using premium (either 91 or 93) and if your engine hasn't been updated, I would use a lead additive. This is just my opinion though, and I would welcome you to get advice from everyone you can so you can decide what is best for you.  |
