Last week i had RP XPR{Race Formula} and E3 spark plugs installed on my car. Overall this week has been very HOT. Mid 90's and i'm pretty impressed. Even in stop and go driving the temp needle will not go past the middle line. Since i installed the E3's i feel a much more defined pull in the mid range.

Gas mileage : 2 weeks ago i averaged 294 miles and filled up with 11.2 gallons.

2 Weeks Ago : 294 / 11.2 = 26.25Mpg

This Week : 311 / 11.1 = 28.01Mpg

Now before anyone says anything. Did the plugs help? I'm sure but let's not draw any conclusions. These are just my observations. That is with a mix of 70% freeway and 30% city. I also have a massive misalignment of the front wheels so i honestly think i could hit 30mpg with this car which is simply amazing.

I use the Royal Purple 5W30 oil, Royal Purple 'Purple Ice' Coolant additive, and ZEX triple electrode plugs. I have noticed a difference in mpg and engine temp. My coolant temp never ever goes above 185 anymore--it used to be over 200* in the summer. I'm pretty impressed with RP's stuff.
