Drove my 07 Toyota Corolla from San Fernando Valley in Los Angeles to Mesa, AZ getting 38 MPG without the groove. Just grooved it myself with Ron's help. Will post gains soon as I return.
It is good to see newer cars respond well to the groove. One would think that newer cars would also have less vacuum issues to fix as well. Looking forward to your mileage results!
While you got more than 10%, remember you're driving one that does NOT like to give up mileage! THAT is a STATEMENT!
Also, it has only just started adjusting.
Thanks for the report. As you can tell, there are others who are curious for MORE... Next time, perhaps you can feed their hunger with your first post!
Just as important, how did the engine respond with regard to emissions. I know the newer cars are tighter but it would be interesting to know if Ron got another "0" to put on his wall.
Welcome to the family and enjoy the groove.
