Normally the car would avg 32mpg but today i checked again and its around 25.
Front nearside tyre is leaking air so i have to fill up every other day but im going to get front tyres changed this friday. That alone couldnt cause such a drastic drop in mpg, right?
I looked in the engine bay and after taking the engine cover off, i noticed its a bit moist in the place where spark plugs go in. Also, one of the connectors that goes into headgasget? is also a bit moist and the screw right under it a bit moist too.
I barely know anything about cars so im looking at some advice. What could cause such a big drop in mpg.
