Hi I recently bought a 08 Holden Commodore SV6 that I've owned for about 3 months. It had no oil, other fluid or water leaks, until Where I usually park it in the garage, tonight I found how should I explain it. A clear SUBSTANCE on the cement. I touched it and it's feels like oil but no so thick like there is water in it, it smells MUSTY. At the moment my Engine Light showing "Check Engine" as in my previous post. ????? What could this fluid I wonder....I believe something seriously wrong, but I could be wrong.
