I got a horizontal engine NOT running alcohol and my oil is kinda foamy. Just got the engine( its on a snowblower). The engine had no oil in it because the crankcase seal was removed. I filled the engine with sae 30 and let it run for about 20-30 seconds. Then turned it off and checked the oil. It was lower than before but not enough to cause damage. It was foamy like when you pour new pop into a glass and you get that foam. My dad says there could have been moisture in the tank which could have been a possibility because the engine was sitting for a year or two. What should I do. Sorry for hijacking your thread.
See the crank will whip a low oil level into a foamy broth quicker with less oil than with more. But both are bad. Water or antifreeze is number 2. I have never seen excessive blow by cause foamy oil unless accompanied by a blown head gasket with anti-freeze leaking into the oil. Drain the oil you have in there (for insurance) after you warm the engine to operating temperature. Then refill to the proper level with the oil of you're choice. I my self prefer Shell Rotella T 15w40. Good luck and make sure you drain all the old oil out.
