Hi all,
I'm struggling to find a product data sheet with ZDDP listed, or VOA for Valvoline Synpower 10w40.
Their PDS shows TBN as 9.3 but doesn't mention ZDDP: https://go.lupinsys.com/valvoline/h...16cf6d/search_api/SynPower_5W-40-PI_Sheet.pdf
The closest I've found is a very helpful member here that posted their Synpower 5w40 results for the past three years:
The readings average to ~900ppm Phosphorous and ~1,000ppm Zinc.
Speedway motors have slightly lower reading, 750p / 950z
In the PDS it states:
Wear protection
Their spiel:
"SynPower is specially designed for vehicles requiring a high performance full synthetic lubricant. It’s unique anti-wear, detergent and dispersant chemistry minimises wear and keeps your engine factory clean for longer engine life. Designed for high performance application 4, 6, V6, V8, naturally aspirated, supercharged & turbocharged engines."
I wonder if Synpower is for modern pushrod V8's i.e. roller cams, as opposed to older flat tappets V8's, hence the seemingly higher zddp content (above ~800), but not the ideal ~1200ppm that's usually mentioned, hence it sitting in the ~1,000 range.
Application:
I'm curious how this would be for a flat tappet engine. Specifically:
Regular street use.
My main concern is making sure it's well protected. Is the oil likely up to it?
I know ZDDP isn't everything - Boron and Molybdenum can also take the place where zddp is lower, if I have understood that correctly? i.e. same protection with lower zddp due to more boron/moly. Only, the PDS doesn't list the amounts (the UOA from the above member do show the amounts though).
Alternatives:
Being outside of the U.S, I don't have access to several of the go-to's (Penn etc.), or they are very expensive due to shipping. In fact, I used to use Driven HR which was priced the same as my daily driver oil. But shipping costs have increased across the board and as such, Driven is 50% higher than what it used to be.

In the PDS it states:
Wear protection
- Zinc additive package provides tough anti-wear protection. Excellent wear protection enhances engine life without adversely effecting emissions system

Application:
I'm curious how this would be for a flat tappet engine. Specifically:
- 1970's 318 Dodge, completely stock
- 1970's 350 SBC, stock or potentially has an RV cam (still in the very mild category)
Regular street use.

- Valvoline VR1
- This is a viable option here, except my understanding and from reading their PDS, it is not intended to stay in the crank case for long. It's ideal for a few weeks / 500 miles, by their recommendation
- Valvoline Maxlife 10w-40 API SN, SM/CF | ACEA A3/B4
- ZDDP levels appear to be lower than Synpower, for Maxlife they work out at ~770z/850p
- TBN: 10
- That suggests that likely the better of the two is Synpower, in terms of zddp pacakge
- Shell Rotella
- A controversial one, whilst it meets the zddp numbers, I'm shying away from it due to it not being recommended for non-diesels due to the high detergent package... from what I've read

I've been a reader of the forum for a few years.I've been using Driven HR for years and now that I'm needing to switch, I became as confused as could be. Some swear that running low zddp on older engines caused them lost lobes. Others say anything is better than what they had back 40-50 years ago.
