I USE IT FOR SHOWS...AND GENERAL DRIVING PLEASURE... IT BURNS A LITTLE OIL...NOT ENOUGH TO MAKE ME REBUILD THE ENGINE. I HAVE BEEN USING CASTROL GTX 20W/50 PLUS SOME LUCAS OIL. I WAS TOLD BY THE CASTROL COMPANY NOT TO USE THIS OIL...AS MY 440 HAS FLAT TAPPETS AND REQUIRES SOME ZINC . THEY SUGGEST CASTROL EDGE. I WAS TOLD NOT TO PUT ANY TYPE OF SYNTHETIC OIL IN THIS MOTOR. HOW ABOUT USING THE GTX 20W/50 WITH A ZINC ADDATIVE??? ANY THOUGHTS ????? FC1221@AOL.COM 917-817-8256 Last edited by magic1; 08/26/15 10:37 PM.

I'm not familiar, but my '80 Aspen 360 is not a roller cam so I use Valvoline Racing Oil, 20W-50 as well. It is a high zinc content and my oil pressure is right where I want it and engine runs smooth and quiet. Facts are stubborn things.

If oil pressure is OK with lower viscosity, no need for the 20W50. Another choice is an oil with high zinc to start with. I guess that is what Castrol recommended. Joe Gibbs, Brad Penn and others have this also. My choice is diesel engine oil. Shell Rotella 15W40. This works for me and many others with flat tappet, readily available and cost effective. Pick your poison. As far as synthetic, the 440 is no different from any other engine. Some additional risk of leaks if changing on a seasoned engine. Mobile 1 20W50 does have high zinc and would be fine with a flat tappet but would not recommend it in your case.

Run what they tell you to if you want to run Castrol oil. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

All I ever run.Ask ten people and you'll get ten different answers,get the actual Zinc content of others then make your choice.
