Mike I'm very glad you decided on having the Groove done to your Lucino, you've done a fine job of sharing your experience here with us. By the time you are back from your latest 2 weeks aboard, this thread will be well past 2000 views!
Seeing the screen shots of fuel consumption data- Yikes it's costing $100.00 or so at each fillup!
Ouch! So I recommend the following to help more: At oil change, use a good anti-friction treat. like RVS look in fuel savers button on front page or go here:
This stuff does work IMHO, Justin Clark knows the product and oil inside-out.
Tire pressure "trick" first fill cold tires to max rating on sidewalls, then try 5 lbs. over that see how it does. Watch treadwear, monitor handling/traction esp. wet conditions.
MPG Remedy look in the Index, or in the (long) message thread here in forum about it. BTW, another G-Man has a different take on it, depending if the gas down in NZ has alcohol content. He uses Acetone with the uncoated aspirin and hydrogen peroxide, instead of alcohol. He uses/prefers gas that has no alcohol, and uses Marvel Mystery Oil as a lubricant as well similar to my use of Lucas Upper Cylinder Lubricant. If using acetone, a lubricating agent is good idea. MPGR has had wide success with Gadgetmen and customers to help economy. I've witnessed one "Miracle cure" w/it's use in an 89 Nissan Maxima, using the alcohol based version.
BTW- Dan Merrick told us early on with this that it can be used in Diesel's as well...(original alcohol based version).
Last, Ron Hatton told us all to open up the spark plug gaps by 20% to increase spark intensity. When you can, you might consider Ignition parts upgrades, see my Plasma Ignition thread-even if you don't go all the way to Plasma spark, there's lots of room for improvements, esp. w/ dist. type ignition.
Check your mailbox when you get back, Mike! And smooth sailing, Mate!
