I had been using VR1 10w30 oil in my flat tappet engines for years. It was over $5 a quart. I was happy to find Quakerstate Defy 10W30 had high enough levels of ZDDP to protect the cams in older engine for a lot less money than the VR1. The they changed the formula for Defy. So I switched to Rotella 10W30. Now it seems they have changed the formula of that and reduced the level of ZDDP. I can't find what the new level is, Does anyone know the amount of ZDDP in Rotella 10w30 T4, T5 and T6 ? I've also read that Valvoline reduced the ZDDP in VR1 is this true does anyone know the amount of ZDDP in VR1 10w30 ? I'm having a hard time finding this information and want to used the a off the shelf oil with the most ZDDP that I can find. Thank you.
Off the shelf oil with highest ZDDP ?

What did you expect? Off the shelf means different things to different people

Motorcycle oil, usually around 1600-1700ppm.
Does anyone know the amount of ZDDP in these oils. I was thinking about using a additive. Without knowing the amount off ZDDP I don't want to end up with too much. I've read that can be as bad as not enough.

One of the stoutest oils out there, Mobil1 0w-40, has 20% more ZDDP than the typical Xw30 SN limit. If you need more, add just 1/4 cup of https://rislone.com/product/3x-concentrated-engine-oil-supplement-with-zinc-treatment/ to boost it even further to about 40% more than a standard Xw30 SN oil (1200 ppm total).

Pennzoil Racing GT has even more. Zddp at 2000ppm. Scroll all the way down:

Is that still true with the current formulation?

I've heard Penrite (an Australian oil formulator) has some select products exported to the US of A. Many of their products boast high zinc, and high viscosity, if that interests you!
If you'd be willing to bump up to 10w40, they supply several oils that could be viable if you can get them at a reasonable price.

Mobile 1 TDT 5w40
Good for gas engines too, more ZDDP than the mobile 1 0w40
I have a ton of this stuff and plan to use it with 0w20 AFE mobile to reduce the amount of ZDDP for less risk of cats going bad.

Where do you buy Mobile 1? It's not on the shelves around here.

Here is a recent VOA of Rotella T5 CK-4 10W-30 right from our forum.
Motorcraft 10W-30 diesel oil says right on the front of the jug that it has over 1,000 phosphorous. It is sold in 5 quart jugs too. My local Walmart has plenty of it in stock.

Yes. All current Mobil1 phosphorus (the limited part of ZDDP) is at:

http://pqiadata.org/ChevronDelo400XLE10W30.html Go look for remaining stock. 1,200 PPM is plenty for flat tappet motors.
PQIA will have new HDEO tests soon with the new formulations.

Thank you everyone. I think on my next oil change I will go with yellow bottle Pennzoil and the Rislone Zinc additive. I think cost wise it's a good way the go and that way I will know my engines have a good amount of ZDDP. I won't have to worry about formula changes in the oils that they don't tell you about.

Excessive ZDDP will prematurely wear your engine.
