Was thinking of running some primrose405 & 409 for colder months. The lows seldomly drop to freezing. Is 409 nessary and has anybody used the primrose 405,409


Thanks, Dave

Lots of people do, don't understand why you haven't got several replies. I used FPPF until recently when I switched to Schaeffers "SOY SHIELD". The guys laugh when I tell them its a Soy Bean product but whe I tell hem so are there tires they get serious. I don't care about the water removal hype or cetane boost, just Lubricitity. Only time will tell if I'm doing right. Edited by: Bill Gisse
