I know a lot of people don't want to hear this, but I swear by it. There IS scientific research that a good molybdenum teflon additive can help.
I am not exaggerating, when I had my 94 classic rover, it suffered dry starts. I began using a teflon additive from MPT Industries. Sometimes I use "Greased Lightening" from O'Reillys. Immediately after I began adding with new oil change in 94, and added with every oil change, DRY STARTS COMPLETELY ELIMINATED.
I then used it on a TR7 (excellent results), a lotus esprit and my latest rover (2001 P38). No vehicle I use it on has any dry starts. I used it on a 1954 Jeep willy. The engine was taken down for a burned exhaust valve (caused by not using lead subst. in gas, nothing to do with oil). Mechanic noted engine was like the day it was built, no signs of engine wear. I also use the gear additive from MPT on my vehicles with standard gear boxes.
All I can tell you is the molybdenum sticks to the metal and I can assure you no matter how some people do not like it, you will not have dry starts if you start using it.
