Hello,
First question - for anyone running a 00 + Tahoe/Suburban, what do you typically get for MPG (summer and winter).
Second question - In September, I removed the original Platinum plugs in my 01 Tahoe, and had the replacement Iridium plugs installed. Without doing a 'scientific' MPG study, I knew right away that I lost at least 1 mpg after they were installed. In all the threads I've read, I've never heard this happening. The vast majority of people indicate a slight uptick in MPG and performance with the Iridium plugs installed.
My driving is very consistent, and the winter blend was not online yet, when this downturn in MPG occurred. I didn't do the wires at the time (has 72k on it), and now am wondering if I shouldn't get these installed soon.
What are your thoughts?
