IM REDOING MY OIL - I WORK IN AN OIL COMPANY SO I GET ALL KINDS OF THINGS DIRT CHEAP SO IM LOOKING TO SEE IF I CAN USE A 15W40 ON MY CAR SINCE I CAN GET IT FOR THE SAME PRICE I WOULD A GENERIC STORE BRAND 5W20 OR WHAT HAVE YOU.

MAYBE A SPIRAX 15W40 OR SOMETHING WOULD IT BE OKAY FOR ME TO USE A 15W40?
MY 440 IS A DAILY DRIVER AND WENT THROUGH MY LAST OIL CHANGE PRETTY QUICK. I THINK I USED 10W30


ANYTHING I SHOULD LOOK OUT FOR?:cheers:

WHY ARE YOU YELLING AT US? Its the internet....no need to yell lol. Is this a bone stock motor? Do you have an oil presser gauge?

this is a bone stock 1973 440 magnum off of a dodge charger oil preasure gauge =yes

I personally wouldn't have any heart burn about running 15-40. I have a feeling most would suggest 20-50 for older higher mileage motors. One thing to keep in mind is you're going to want an oil with zinc in it for your flat-tappet cam.

CORRECTION - oil gauge reads at 60-70 psi
