I did a test using Power Services white bottle cetane boost additive. On a 1,000 mile trip, I alternated tanks with and without. The fuel economy consistently increased from 18.5 to over 20mpg when running the additive and back down when not. I'll use the silver bottle now that warm temps are here.

That was in my F-250 7.3 Powerstroke, 3.73 rear end, 2wd, singe rear wheel.

I'm currently running a test on my '82 VW Rabbit diesel 1.6/ 5 speed. Without AC, best I got was 51.3 but all highway. AC knocks it down to about 45. This last tank was an 80/20 mix of highway/town driving. Economy without AC was 49.6mpg. I'm currently running the white bottle additive and will report back on the economy at my next fill up.

By the way, the naphtha is a great solvent but the cetane boost comes from the ethylhexl nitrate. The naphthalene and 1,2,4 trimethylbenzene are both ingredients in a common high flash naphtha.
