Re: Oil level go up! Volvo Penta 4,3. GXI.
1. If gas was getting into the oil you would be able to smell it, and the oil would be thinner.
2. Anything in an EFI engine that would put that much raw fuel into the engine oil would make the engine run terrible.
3. Check the oil after the engine has been off for several minutes to let the oil level settle down to normal.
4. Remove the dipstick, wipe it off and then re-dip to check the oil. Don't just pull it out and check the oil. It will never be right that way.
5. When checking the oil with the boat on a trailer, make sure the waterline is about level if you are comparing the reading from when it was in the water.
