Hi everyone, I ordered a UOA kit that has a tube and a syringe to get the oil from the dipstick, My questions are: 1. Does the oil need to be hot, engine running, engine just switched off, or cold is fine? 2. If the tube does not go down the dipstick what is another way I can get to the oil without draining it? Can I remove the oil filter and extract some oil from there? Or can I remove the oil cap and try to get some from the head? 3. The kit came with a 30cc syringe and a 100ml or so canister. Is 30cc enough for the lab or must I fill the canister?
