I would agree. Anytime the engine is running more efficiently it makes more power per unit fuel. That means I use less fuel to do the same work. Gas saved.Wonderful news and great information for the archive here on the board! Thanks for posting it up.
I've always been a bit dissappointed with my fuel economy. I check it regularly and haven't been above 24.6mpg yet. I've seen others report 28 (IIRC) and your post makes me wonder if the cats play a role there. What do you think?
I never used to have to worry about spinning tires unless I really flogged it. Now it is quite easy making a curb lane turn (right), especially on an incline. I fear I will now be eating tires. (a good problem considering the alternative).
(Rockauto)For future reference, please post where you order from and if you don't mind, share how much you paid for all of it.
