So after the valve lash, and oil change, tranny oil change,
and a change in oil brandnames had me thinking what kind of differences might I make.

I have been using in the tranny, Royal Purple Synchromax.
And for motor oil, the royal purple 5w 20.

attatched is a picture of my mileage, it was reset before i started the car after filling up with 93 premium. This wasnt ALL highway mileage, and it wasnt all city. I even did a few races and fun stuff on the streets.
So just to explain that i didnt baby the car to milk mileage...
I drove how i normally drove.

The car was washed and waxed on day 2 of the fill up,
the fill up was done on thursday after the valve lash was set straight.

The red light turned on at the indicated number below...
I used to only get about 290.

 

I average about whatever equals 107% * 220 miles... since i have oversized tires my od' reads a little slower...

Also note, i'm a VERY spirited driver...

 

I have barely managed 190, coasting down hill, not reving it. a few spirited pulls but not many

 

I get around 220-250 til the light comes on.....I did notice the milage get better after I got the p&p IM.........

 

my record is 617 km's or 383 miles. That was all 100% highway, never driving over 100kms/h or 60mph and never using mivec. But that was really boring driving so i usualy dont care and jus givr'!!!

 

I got 372...crazy stuff there...im trying to get better now. I love good gas milage. I will have a pic up by tomarrow

 

260 the most

 

whoa,
thats astronomical...
im takin a trip from buffalo to philadelphia on august 10th,
and this mileage has me smiling about it...
cause straight hwy mileage means ill be getting up there...
but you bet ill have about 5 layers of wax on the whip before i take off...
haha, it will glide through the air... wind resistance wont exist!

Im still blown away at 372... i thought i did awesome...

 

I just kept it at around 60mph so it wouldnt go into mivec and I wouldnt shift over 2,500rpm's

 

Somewhere in the 370's. I could've gone more, but you get to that point where you're not sure how much longer you have before you're out. Came out to around 31mpg and change. I only get that high when I'm really trying to get good mileage, which as someone else pointed out, is really boring. Normally I get around 300-315 per tank (around 29mpg)

 

385 and that was leaning it out with a piggy and highway cruising @ less than 65 mph

 

I more or less get the same in the city.
