I have a jdm d15b running on a p28 and the engine makes 220 miles on a full tank. Is that normal. Am i running too rich? Should i get a p08? With the z6 it was making at least 250 miles per tank. Thanks.
The car is a 93 del sol si . Don't really know the size of its tank sorry. 80% highway . 20% city. In the city, i have been gentle on the pedal to see how many miles i can have on a tank with the new engine. Oh i forget to say the car is an auto (does it make any difference?) Thanks.
The only check engine light i've been dealing with is the code 22 (vtec pressure). The thing is that every morning i have that cel. But once the car is warm if i turn it off and restart it , the cel desapears.
