    IMG_2836.JPG So i have a D16y7(No Vtec). when i bought the car it was running conventional oil and I decided to switch it to full synthetic oil. I noticed the car keeps running out of oil About every 200 miles. the car never leaks oil but the oil pan and the bottom of the transmission always seem to have an oil residue or grease on them. I even tried putting paper and cardboard under the car after many drives and no leaks. So I decided to dyno the car a while back and it turned out to be that my car is running rich. So far i have replaced the oil drain plug and went to the many screws surrounding the oil pan to tighten. I tested the car an on average it runs 25MPG. For those who wanted to know the car ran 100 whp on the dyno.

    It's very common to develop oil leaks after switching from conventional to synthetic oil. Locate and fix the oil leaks (e.g., distributor, oil pan, valve cover, oil pump, valve cover, front crank & cam seals, rear main seal).

    The oil leak and running rich are separate issues. What exactly in the dyno makes you think the engine is running rich?
