What oil has the most ZDDP?

[MrWideTires]

So.. What non-racing oils have the highest ZDDP?

How much does GC, Mobil1 5W30 EP, and Amsoil S.S. 0W30 have?

Just wondering if I have the right stuff in my crankcase?

 

[chevrofreak]

I'd say Rotella 10w30. I've seen VOA's of that stuff that showed around 1700ppm.

Amsoil SSO 0w30 would have the most. I can't remember what the exact number is but I believe it is in the 1000 - 1100ppm.

I use this oil in the winters and it is superb.

I don't know the exact numbers but I know Red Line has high ZDDP and Moly.

Redline has alot, but for 10$ a quart it [censored] well better

Here is the VOA for Amsoil SSO 0w30 as posted by another member in the UOA section.

Here's an extensive ZDDP article from the Opel Club.

A bunch of modern oils and break-in additives are quantified.

The oils mentioned don't have particularly/relatively high ZDDP compared to HDEO's.

Which engine and car are we talking about?

 

[chevrofreak]

Rotella 10w30 is an HDEO.

Mr. Wide - you may have the right stuff in your crankcase with an oil with less than the highest amount of zinc.

Their street/race oils contain 1200/2500 ppm of P repectively

I would say the three oils you list will be just fine and no undue wear will occur due to lack of ZDDP.

 

[chevrofreak]

Yeah, there's no real need for high zinc in that car.

Mr. Widetires

Understand that the zinc, bound in a zinc phosphate compound, is not THE ingredient for a robust oil. Oils are a combination of ingredients. The ZDDP compound is just the cheapest highly effective antiwear and antioxidant agent. Reduced zinc levels plus other ingredients do a fine job. Some old engines, especially if they have especially high pressure on the valve train parts due to high performance parts substitutions, require more antiwear and antiscuffing agents than modern oils, but this is very few engines, and probably no modern engines.

The lowest cost way to get a very robust oil that is also high zinc is to use one of the 10w30 or 5W-40 dual-rated diesel & gasoline engine oils. Buy whichever you find first...they're all very good.

Is zddp the only additive/element used in energy conserving oil prevent oxidation?
