ZDDPPlus ZDDP Engine Oil Additive Zinc & Phosphorus 3 Bottle Pkg

Update: I don't know why but this product/brand turned to gel after 3 months???..going back to lucas brand.I know all the chemistry involved here and I don't care what they say about zddp and cats and air quality....zddp is a proven additive and is far superior to moly. I have 2 new vehicles. And given the high valve train failure on some of these new vehicles I add 2oz ( half bottle) to every oil change which puts me at around 1000 ppm which is safe for cats, I use castrol edge euro oil because it's the highest rated for protection, which I have tested by Blackstone labs regularly....it works.

Everything was great

I have been using ZDDP on all my cars for years. The product adds back anti wear zinc to modern oil that no longer have it. It is top of the line in preventing engine wear. The bottle says not to use on cars with catalyst, but I have no problems what so ever. I will also say that ABC's customer service is great. I did not receive a shipment one month and they resent it to me immediately. If you want the engine to last add this every oil change.

Would buy again

This is a must have for the earlier engines especially the "Non rollers" the major oil companies pulled out a few of the anti wear additives due to tight "cats" clogging on late model cars etc one of the main additives was the ZINK got to put some back in....recommend.....

Our engine builder instructed us to us a product such as this. We have followed his instructions to the letter and have had no problems.

great product

works great
