I'm used pennzoil off and on for years, always does a good job of cleaning sludge out and my oil pressure stays steady.

Me an my dad havr always used pennzoil in out race cars an street cars never used any other oil products :)

I had purchased this oil after a previous owner failed to do regular oil changes on my car cleaned the sludge and keeps her running strong
