14 MPG
Hey guys, so yes its another MPG thread
 So my car is getting 14mpg  Thought it would be a small thing that would pass but its been this way for about the last 3 monthes of its driving cycle. Its stored currently but I guess the last month of driving did have winter blend fuel. Without winter blend I would say it was about 15-16 mpg. The car was driven the same way it was before and it was achieiving 21mpg The car now has 50,000km (31,000 miles) I havnt changed the plugs yet, I did do a seafoam treatment back in September. Mods on the Car are the following Vararam Solo Cat Back Black ICE All these mods were installed years ago so dont think I can blame the mods. SO heres my dilemma, im not sure where to start to isolate the issue for the terrible MPG. Heres my possible problem areas: Air leak on the manifold from the black ice? Bad plugs Maf Sesor? (it may have gotten sea foam on it) I mean I dont know what else can cause it to be soo bad. This has occurred through several tanks of gas. Also want to say sorry in advance for the structure of this post, lack of sleep. Is there anything else that could be causing it? No CELs, no mis fires that I can feel, and yes I did the usual checks such as tire pressures, air filter etc. Any help or input would be very much appreciated Ps anyone know how to test the manifold for leaks? Ive heard of smoke methods

Last time you cleaned your air filter?
To check for leaks, spray around the manifold with some carb cleaner... see if the idle changes. Get some MAF cleaner and clean the MAF.

 Then check after a couple of tank fulls of new fresh gas and make sure your checking the MPG correctly. Any one tank can give you miss readings. If you did not fill it the same everytime. I know becasue I have every tank full recorded and see the numbers jumping around depending on the total fill up, how it was driven, temperature plays a huge roll too.

The Vararam is supposed to be oiled. From that video I'm not sure if it was oiled or not. That was a lot of dirt passing through.
