I have been running 15w40 Delo 400 with Royal Purple break-in oil in my 383 since I had it rebuilt 1000 miles ago. After comparing oils with Zinc/Phosphates in them I have decided to use Brad Penn. Here is my dilemma, should I use 10w30 or 15w40? I live in Ohio so temps. are anywhere form say April to October 50's to 90 degrees. Car runs 180 to 190 all day. Now, which do I use? I can get Brad Penn $50.00 a case which is 12 quarts, not too bad! Please help me with my dilemma! Thanks!

If it seems high at a idle when warm try the 10w30. Im currently runing 10w30 in my fresh 440 no problems

There is a oil company distributor of this oil within a few miles that they will only sell it in cases and not single quarts. The case of 12 for $50.00 works for me. And at $4.00 a quart you can't be it. The other guys can't even come close to that. Joe Gibbs, Zalt, Amsoil or even Edelbrock and compcams oil can't seem to want to touch that price with a ten foot pole.

Well according to the trusty 1969 Plymouth Service Manual here, it's specifying 45-65 PSI operating pressure @ 1000 R.P.M. with a minimum pump pressure of 20 PSI @ 500 R.P.M. But your oil pump could be doing excess by-passing with the 15W-40. I'd still give the 10W-30 Brad Penn a try with NO aftermarket pour-and-pray motor oil additives. CompSyn

I just did an oil change yesterday in my 451, using the Summit 10w-40. Bottles say manufactured by I.L.C. in Brookfield Conneticut. LemonWedge - Street heavy / Strip ready - 11.07 @ 120

Plus, it would be a real bummer to twist or break the intermediate shaft because of the excess torque required to spin the pump...
