Valvoline VR-1, Driven racing oil, Penn grade Are all great. Buy the oil made for the job, forget the ZDDP additives in off the shelf Modern motor oil. It has too much detergent and it fights your additive. many oil tests test the oil, then when thy put in the additive in the same oil the...

You can get the Penn Grade oil from Summit and the good WIX oil filter too.

...probably not too different from Maryland where I live. I think your choice of oil is a little light as regards weight. In my 440s, I run Penn Grade 15W-40, and I use NAPA gold filters. Sounds like you got the right filter, but your choice of a conventional oil is not a good idea. Penn...

...Cams 15W-40 break-in oil. I figgered: it's their cam - therefore, I'll use their break-in oil. Cam break-in went well, and I'm still running that oil, since I have fewer than 400 miles on the new engine. After a few more miles, I'm gonna dump it and fill the crankcase with Penn Grade 15W-40.

...-- an amazing price in light of current petroleum product price hikes (e.g., it is half the Lunati price at Summit and 40% less than the Penn Grade 15W40). That will make a big difference (almost $100 with tax) on 2 oil changes, and since the VR1 has gotten very good reviews from most...

I hear ya. . . I use Penn Grade 15W-40 in my '66 300 440s. Quality oil with high ZDDP content needed for flat tappet cams. You can get it from Summit.

And there is my answer...

...and exhaust - hence the 30-30 cam. You should have heard that thing! As regards oil: The 10W-30 oil may be a little light. Is it a break-in oil you are using? I would probably go with 10W-40 or even 20W-50. I would also be sure to use a high ZDDP content oil like Penn Grade. Love yer poly!

Yes. Penn Grade does.

I have been using Penn Grade 15W40 in Medina, happy with that oil so far (changed it twice already, 5k miles and 2.5 years). At the suggestion of @david hill I bought Valvoline VR1 10W30 for my 1970 TNT 'vert and will be using that oil in that car. Question: Ming's engine was just rebuilt (head...

Penn Grade all the way!:thumbsup:

Thanks much for that sound advice! Can't wait to share what this car sounds like running again :) Thanks! Sounds good, thanks for the tips! Very true :)

That's one of The Very Best, isn't it? About 1400 ppm Zn or so?

Nothing but Penn Grade here. I’ve always run straight 40 weight in my almost 160k mile 440 however this year I started driving it regularly a lot earlier so I’m running 10w-40.

I don't mind it at all! Thanks! I'm using Castrol gtx but I added the Lucas zddp stuff they make. I broke my cam in using Schneider cam break in oil Ill do an oil change and try a 20w-50 and see if I can find one with zddp in it instead of buying a bottle to add.

Well I will be the exception. Can't remember if I lost one or two cams on VR1, but I switched to Driven some years back when I lost 3 cams in a short span. 440 and 383 engines - nothing crazy. Its the old Joe Gibbs oil. Its not just zddp - its the whole package.

Seriously what’s the difference between the Penn Grade and the cheap “5 quarts for 12 bucks” oil you get at Walmart? I’ve been using the cheap stuff in all my daily drivers for years without issue, changed every 10k.
