Thanks

valvoline racing 50 with comp cams break in additive for first 3000 then royal purple racing 20/50. i change oil every 1000 for first 3000 after first fire up. so 4 total in 3000. all with comp cams stuff. but i am just anal that way. clean oil is next to ............u know the rest

I use the 20-50 Valvoline Racing oil. Make sure it says racing. If it does not say racing it will not have the zinc additive that is needed. You should also use ZDDP plus in addition to the racing oil. I would stay away from any synthetic oil. This information is more important if you are runnung a solid lifter cam.

I've been running Delo 400 (same oil I run in my F350 PSD) because of the added zinc ( zinc dithiophosphate or ZDDP ) in current FE build since break-in which now has 3Kmiles.

From ad for ZDDP Plus Oil Additive:
After 70+ years, the EPA mandated that all domestic oil producers remove ZDDP (Zinc Dialkyl Dithio Phosphate) from all conventional and synthetic motor oil. If your engine was designed before 1989 the non-roller lifters require ZDDP to avoid premature deterioration. ZDDP also alters bearing and journal surface characteristics to prevent metal to metal contact. Under extreme conditions like a high performance motor, ZDDP reduces the tendency of parts to scuff or gall under heavy loads.

I haven't used this additive but I did go with Delo because of the added ZDDP and the protection it provides. I have since found that "newer" Delo 400 LE (Low Emissions) does not provide ZDDP at the same levels as the older version of Delo. I am going to do further investigation on ZDDP additives.

Thanks for the post.

I use Rotella T ..15W-40.

Mike:
The EPA has made no such mandate. The ZDDP in any "starburst" oil has been reduced to 800 PPM. This is plenty for all current detroit production (roller everything). For the rest of us with non-roller everything it would be wise to use an oil with a higher amount (at least 1200PPM) of ZDDP.

Myself, I'm using Redline 5W-30 (non-racing) oil which has 1,200 PPM ZDDP. I'm not sure what other brands have the higher ZDDP in the thinner viscosity I prefer. All the heavier oils have it.

10w30 Rotella in the SOHC.

[danc30]

Regular Castrol 10W-40 per the engine builder, Keith Craft. (he said any major name 10W-40). I trust his judgement.

[RodKnock]

Redline has one of the highest ZDDP counts in the industry. I use 10W-40.

I'm also running Valvoline 20/50 Racing Oil.

Valvoline VR-1 20/50 racing oil was what my builder recommended

Bob,

PLEASE READ MY POST----------- It say's "From ad for ZDDP Plus Oil Additive:" This was found on their web site


MORE regarding EPA according again to ZDDPlus www.zddplus.com

" As part of an effort to reduce vehicle emissions, the U.S. EPA offers vehicle manufacturers "credits" for early implementation as well as penalties for violation of emission reduction standards. The EPA's program called for 100,000-mile catalytic converter life by 2004, 120,000 miles by 2007, and 150,000 miles by 2009. To achieve these goals, automotive manufacturers have pressured their oil suppliers to remove substances from motor oils that would shorten the service life, including the proven EP (extreme pressure) additive ZDDP (zinc dialkyldithiophosphate). Zinc and phosphorus from the ZDDP can be present in small amounts in the exhaust gas of an engine depending on the amount of oil which is consumed in combustion. These elements can coat the catalyst reducing the amount of catalyst exposed to the exhaust gases, ultimately increasing emissions at the tailpipe. As a result of the EPA mandate, the ZDDP level in engine oils has been declining since the mid-1990s, roughly coinciding with the implementation of OBDII."

So it appears that the reduction in ZDDP is the result of the auto manufactures "mandate" by EPA to reduce emissions and not a direct mandate to the oil companies.

The more I read up on this topic the more questions seem to arrise. Do check out the link I provide above for some basic reference info. It appear's that bottom line is that oil zinc levels have been reduced to help auto manufacturers meet EPA and that an addive is needed for older "flat tappet" engines to prevent premature engine ware. GM EOS and ZDDPlus appear to be additives to consider.

I used up the last of the 3 cases of Rotella I bought before they reduced the zinc. This spring I'm switching to Brad-Penn as it has high zinc and phos.

Not being a SA but this one of the most ask questions on CC, If you really get down to the basics, all commercial oils are fine. If there was a poison out there, you would know about it real soon. That being said, I run rotella and add MoS2 about every third oil change.

Here you go Mike. http://www.zddplus.com/index.htm I bought a case to use since I went with flat hydraulics.

I use 10w40 Kendall Racing Oil, and I add two bottles of ZDDP Plus additive...

[scootter]

Randy,

Is that a 20W 50? I haven't found a 10W 40 with the additive which I like to use.

Scott

[Randy Rosenberg]

10w40 - I add the ZDDP Plus (two little bottles)...

[Monster]

Scott/Randy,

I saw on the ZDDPlus site that the distributor is in Stockton (www.davidnavone.com ), Randy is that where you are getting yours?

Thanks,
Mike
