Engine Oil

[Nassau1969]

What engine oil are you using in your 440 (1969 1970), I'm using Mobil 1. Is it to thin for these motors.

nope, but it doesnt have the ZDDP that you need to rejuvenate the metal components in your engine without an additive.

Royal Purple XPR 10w40 will be preferred, because it has good availability.

I haven't had to consider oils for 3 years now lol.

My past 'field testing' (7500RPM Sportster 883's) showed only a few oils which would prevent piston scuffing;

Royal Purple Racing
Bardahl Racing
Amsoil Racing
Klotz Racing
Mobil 1 20w50 (probably no longer)


Obviously, this is high-speed testing and the particular problem on these bikes is piston scuffing. There is no direct comparison to traffic-jam flat tappet cams with high spring pressures. YMMV.

Is it to thin for these motors.

Too thin depends on your specific motor, stock or mod, environmental conditions, your driving style, etc. I think it's reasonable to say that "too thin" is ultimately determined when your see what the wear looks like inside the engine. But too "thick" will be just as bad with every engine start, let alone in freezing weather (say a straight 50 or 60 weight)

All of us (most?) select the weight and type that we hope has the highest probability of optimal lubrication for 95% of our typical driving. And keep our fingers crossed.

VR1 10-30 (conventional) works great for my Hemi and my driving. I change it often. If I raced more I'd use 20-50.

Switched to Joe Gibbs HR 10w-30 a while back. It'supposed to have the Zinc our flat tappet cams need.

I use diesel oil from Rotella t, It has the old properties that the old oils had back in the day. Johnny

You're answer is right here.

im using valvoline VR1 69 440

[charger2fast4u]

so pretty much if you have older engines like us you most likely need to run an oil additive unless your oil brand you use has it already added in? i use castrol 10-30 in my 440. i'm not to good with what oils to use in what temperatures and motor applications could someone set me in the right direction on this? what weight oil is good to use in a  stock to mild 440 during summer anywhere from 70-100 degree weather? also if you use a zink additive like ZZDP how much do you put in with your oil? about to do a tune up and change the oil soon lucky a thread like this came up before i make a mistake.

Seconding that.

Based on what I've read I'd have to agree, Rotella isn't what it once was.

Mobil 1  15W-50 +  Comp Cams break in lube.  Mobil's web site states that 15W-50 has over 1300 ppm ZDDP which should be enough and recomends it for older style engines. I still am adding the break in lube, probably overkill . Change it once a year , about 5000 miles.  15.000 miles on the build, so far. so good.
