1995 Miata, pretty much stock. has 91,xxx miles on it. I switched to sythetic(yea my b) after it having conventional most of its life at the last oil change. About 2 weeks ago I checked it, it was a bit low, I added about a quart. Got off the interstate today and it was ticking. Limped it home and found that I had MAYBE 2 quarts of oil in it. I live in an apartment complex so no real way to check for oil spots. Doesnt seem to be leaking from anywhere and the car doesnt smoke. Anyone know where my 3 quarts went?
