I've been doing some looking around online for a while and can only find anecdotal information regarding gasoline lubricity and lubricity of additives. I became very interested in this after getting my wifes '03 Jetta TDI which does have hard evidence supporting the addition of fuel additives as shown by the Spicer Report. Is there anything similar to this for gasoline? Seeing MMO having such a negative effect in D2 and TCW-3 having a great result I'm apprehensive of running MMO in my gas engines ('93 Saturn SL1 and '95 Yamaha XV1100). Right now I plan on running around 10k miles, pulling plugs with no additives, 10k with MMO each tank, and 10k with TCW-3. I noticed a good bit of ash build up on the plugs after 30k miles when I changed them this round but I've used a variety of additives inconsistently. But I have a feeling this will have too many variables to be very conclusive (temp variations, running A/C, being the main two).
Is there any conclusive information for gas additives? Any tips for making this an effective test? My normal work commute is 57miles round trip and I almost always fill up at my place of business.
