From Wkipedia on tetra ethyl lead:
"In most industrialised countries, a phaseout of TEL from motor fuels was completed by the early 2000s because of concerns over air and soil lead levels and the accumulative neurotoxicity of lead. Leaded fuel also spoils catalytic converters, which were introduced in the 1970s to meet tightening emissions regulations. The need for TEL was lessened by several advances in automotive engineering and petroleum chemistry. Safer methods for making higher octane blending stocks such as reformate and iso-octane reduced the need to rely on TEL, as did other antiknock additives of varying toxicity including metallic compounds such as MMT; oxygenates including MTBE, TAME, and ETBE."
A TDI gets better gas mileage than a hybrid except in an actual car driven on a real road. The higher cost in the US of diesel fuel negates any advantage it has over even non-hybrids.
Keep swinging hotshot. Statistics dictate that you'll connect by accident someday.
Sure thing Tojo. I see your understanding of cars is as poor as your scientific acumen.

"58.82 MPG World Record set by Jetta TDI
Herndon, VA – The most fuel efficient car across North America is not a hybrid. It’s a diesel. A Volkswagen Jetta TDI Clean Diesel, to be exact. Making its way across the nation and into a world records, a Jetta TDI recently achieved 58.82 MPG during a successful 9,419 mile bid for the lowest fuel consumption across the Continental United States. Despite being officially rated at “just” 30 MPG city and 41 MPG highway by the EPA, the Jetta TDI managed a whopping 14 percent improvement over the previous record of 51.58 MPG.
Set under real world conditions with a completely stocked Jetta TDI, the record attempt began on September 5, 2008, in Washington D.C., and passed through (take a deep breath): New York, NY; Rutland, VT; Toledo, OH; Des Moines, IA; Spearfish, SD; Missoula, MT; Winnemucca, NV; Santa Monica, CA; Durango, CO; Oklahoma City, OK; Mount Vernon, IL; and Ponchatoula, LA; before finishing up 20 days later and 11.04 tanks of fuel lighter in Beckley, WV. The world record was achieved using simple driving techniques that maximized the already exceptionally efficient TDI engine. Despite the less than ideal weather conditions, varied terrain and frequent traffic congestion, the entire journeyÂ’s fuel cost came in at a paltry $653, with the Jetta TDI Clean DieselÂ’s average consumption costing just 6.9 cents per mile.
