We recently bought a 1990 Honda Civic Dx hatchback and the engine runs smoothly, no major performance problem, we change air filter and a bunch more things, however, when we checked the oil we manage to take out only a little more than a liter of engine oil. We found this odd but when we filled it up the same thing happen it only manage to take a little more than a liter. I'm wondering if this is normal or is there a problem with his car? has this happened to you? Thank you i really appreciate it a lot.
