I know this has been beat to death, but I been running 15-40 Rotella with ZPPD for a couple of years since freshening engine. I noticed some posts claiming long term use of such could do more damage than good. What would be the best oil to use with ZDDP for a 440 street engine?

I agree it's beat to death. I break my engines in with a GOOD Quality 30 weight with Comp's additive then run Valvoline VR1 10-30 after that. never had a problem

You can use the Heavy Duty Engine Oils (HDEOs) in older gasoline engines just fine. Many people here are doing so and have good luck.

This directly from the Shell Rotella main page: "Many gasoline engines, especially the hard-working engines of pickup trucks, sport-utility vehicles (SUVs), minivans and motorcycles"

Recent lab reports have Zinc content of the new formula CJ4 Rotella in the 1200ppm range, which is an accepted level for flat-tappet cam use.

Some fear this Zinc level may be reduced at any time without warning.

If you don't want to continue to use HDEOs, there are many options out there for high zinc non-HDEO motor oil.

Also depends a lot on the lift/duration of your cam and the tension on your valve springs. Gonna be a big difference in how concerned you need to be between a stock cam/springs and an aftermarket setup with .6 of valve lift and 600# spring pressures.

I have the same concern. I just primed my engine with a drill and it made 80 PSI. Am just as concerned about the intermediate gear as I am about the cam and lifters. Do you think I'd need a bronze gear? Bill

I do have a higher lift cam and valve springs. So what oils do you reccomend?

I run Rotella for my flat tappet cams. Anything on sale for newer daily drivers. You definately have to pick an oil for your application as is why there are a few custom oil companies. Everyone I've talked to lately is fawning over Brad Penn oils.

I run a big Hyd ( over .600 lift ) flat tappet cam and use Royal Purple racing oil with a zinc additive. No problems so far.

what motor and cam. oil pressure will not hurt anything and goes down quick when hot. bronze gears are for performance roller cams not sure about stock hydraulic rollers though?!!

I think the reason you run bronze on a roller as rollers are billit steel not cast and the need for dis similar metal contact?? something like that??

How about 10W40 valvoline or 10W40 castrol gtx? Are these good oils for a street 440? Would I need ZDDP?

most believe you need additive with any SM rated oil.

One of the reason a lot are switching to Brad Penn,check the Zinc content.

I run VR1 in my Hemi w/ 590 solid & no problems. Easier to find than the Brad Penn I used to use & a lot cheaper. Check out www.bobistheoilguy.com for more info about your question.

I run valvoline Vr1 20w-50 in my car. I ran two samples so far and the zinc is 1172ppm.


The only Carbs I care about are under the hood!

I run Royal Purple in just about everything I own. I have never had an oil related failure with it.

I've been running Rotella 15w-40 for a few years. I don't like that my oil pressure is a bit high with the 40 weight oil. This fall I'll change to a non-specialty 10w-30 with a dose of ZDDPlus.

Rotella is now SM rated. I know that some feel that you need SL rated oil for older engines with flat tappet cams. Tractor Supply Company's house brand oil is also a 15w 40 oil and it still has an SL rating and is available in container sizes from a quart up to a 5 gallon pail.
