I did a tune up and installed Bosch Platinum+2 spark plugs in the fall. Since then my MPG has decreased by at least 10%
I used to get over 20 MPG on the highway, now if I'm lucky, I get 17-18.
What is your opinion on these dual ground plugs??
Has anyone else had a similar experience??
I expected better MPG, not worse...

"More platinum in the center electrode with two yttrium-enhanced ground electrodes and a more powerful spark.
If you require smoother acceleration, better gas mileage, and optimum engine performance, Platinum+2 is the spark plug for you. Unlike conventional air gap spark plugs, Platinum+2 uses surface air gap technology. The spark of a Platinum+2 first travels over the surface of the insulator nose and then arcs across the air gap to a ground electrode for a longer spark, without increasing the voltage requirement. Plus, the yttrium alloy ground electrodes help to reduce gap wear and oxidation, extending the service life of the spark plug.
Only Bosch offers this revolutionary firing technology, which combines the advantages of platinum, multiple electrodes and surface air gap technology for optimum engine performance. "
Blah, blah, blah....
