Zddp

How many of us here use ZDDP additive in their oil? I have never heard of this stuff until just today and I think that I wouldn't mind using it. It sounds like that it is a good idea. Hey, maybe if I buy those POS SE Lifters then I can use it???

Why do you think you need an oil additive?

Some people are experiencing some frosting on their lifters and they using addp to combat it. I thought it was weird because A.) I had never heard of the additive expressed that way 2.) Didn't realize how little of this exists in oil. when I looked up the Wiki, it is basically just adding zinc.

People on HTT were discussing this in a thread that I started asking for their experience with SE Lifters, which I think that I may steer away from. Think STP here as an additive that adds zddp.

Just set your money on fire. Bout the same as adding an oil additive to a decent oil. Just saying is all.

Amsoil, Royal Purple, Mobil-1 dont need an additive.

What is frosting?

If you look at the picture, you can see of discoloration. The sides of the rollers are more metal looking while the centers of the rollers have a milky color to them. I can only assume that that is what is being referred to as "FROST."

Thats cuz them *******s run more spring pressure than they should on a hydraulic roller cam . Dum ass some of them boys run over 500 lbs over the nose that poor lifter and push rod are doing the work of a mule trying to get the valve open . And they are only running in the 650 range of lift .way more spring pressure than they need for a street ridin bike . 150 .330 .is more than enough to run in the 600 lift range and the valve train will last100000 miles and keep a nice valve job for many years . I know if it on the net they must be correctly building twin cam motors . Lmfao

I don't run synthetic oil so will the Zddp work or is it as necessary with dino oil?

Valvoline vr1 20 w 50 haz all the zddp you need

Can't find vr1 20-50 here,I'm using Castrol 20-50 motosickle oil...wouldn't any oil rated for use in motorcycles have enough zddp in it??

Depends ? Zink and phophurus were removed due to converters being damaged . 09 and up bikes have converters so I don't know if all motorcycle oils have zink and phosphorus in them . I don't even know at this point in harley s oil has it removed that's why I run vr1 racing has a good zink package .

Hmmm,that's right,I never thought about that....the Castrol has a SG rating and I've been using it for a long time....zinc package started being diminished from SH rating and up....I think the automotive oil now has a SM rating...

Info I picked up a while ago is that SF or SG rated oils are OK for motorcycles...after that

Oh, just pour some SAE 50 racing oil in the bag and fergitaboutit!

Too cold up here for straight weights....any oil is better than no oil

Don't wanna get an oil thread goin'....does Santa's girl on the right look a little like that Irish sunbather??:drunk:

Yes, and I just LOVE pale skinned women!
