When I have my 2002 ZX2 (with a 2.0 L Zetec engine), curiously it said in the manual that it required 5W-20 oil. I put 5W-30 in, as it was the spring, and it ran fine...maybe if you can find some 5W20 that might help, as it's a little bit thinner.
Then again, stick with what your manual says...that's usually safest.
