Default Foaming Issues with Brad Penn Oil..

For the last 4 years I've been having issues with Brad Penn oil foaming when the dip stick reads full.. I had to run it a quart low.. This is on two different motors.. The 454 would tick after pulling long hills if it wasn't a qt. low..

At the advice of a few local engine builders and 540rat, I switched to 5-30 Mobil 1 full synthetic.. What a difference!! My stock flat tappet 454 is quiet, the oil lamp doesn't stay on for a few seconds during cold start warm up and no lifter tick...

From what I've been lead to believe, cheap oils have wax in them that cause foaming..

I've had no issue's with Brad Penn 15-40 and been using it for years. Brad Penn has some of the highest levels of zinc around. I do not think Mobil 1 has the level of protection you need for a flat tappet

Sounds like you need a windage tray.
