it seems Roush and Valvoline have teamed up: http://www.roushoil.com/sae-40.html http://www.roushoil.com/zinc_chart2.gif haven't tried it myself but i see they're making ad buys in the circle track magazines.
Not for street use id bet too hehehe stupid EPA Like a bootlegger, the product will get through by hook or crook
That looks good to me. I was planning on finding some of the Bradd Penn oil for my next change but will probably use this stuff instead. I have been using the old formula Rotella previously. Bert
The closet dealers to me are all Ford dealers. Its close to Holloween I guess I could wear a disguise when I go in.:laugh: Bob H.
[long trench coat pulled up high, dime store dective hat.] -Probably gotta ask for it like asking to buy drugs.- Pst, hey, do - ya - got any [lean in] "break-in oil" wink wink I need it for my glocomia cough cough. -As the EPA secret aget is peeking over a newspaper watches you.-
The only thing that concerns me is the potential for leaks to begin when I switch to the synthetic oil. Any opinions on the likelihood of the leaks starting when I switch? Thanks Bert
I've used Brad Pen break in and their raceing oil in my 455 since new.I talked to their engineer and asked about the synthetic portion of their oil and was advised it is a very small amount.He didn't give me the % of synthetic ,but assured me that oil leaks would not be a problem.The % of zddp is .012 by volume,and is classified as a raceing oil.
I don't know how the .012 by volume converts to ppm, but it is common to find oil for diesel engines with 1200 ppm zinc. Might not be much advantage to using this racing oil, not if it costs a lot more than diesel oil.
Select Ford dealers have the exclusive "Roush" franchise to sell the "Roush" Mustangs. They also have access to everything Roush.
Jim ,some oil Co. use a % by weight and some use ppm it appears to me to be the same figure.After re visiting the Brad Penn site i quoted the incorect figure for the zn.The 10/30 racing oil is stated having 1500 ppm zn and 1340-1400 ppm.phosphorus.As for the cost i'm buying mine for $5.50 a bottle and have it shipped from Seattle Wa.The cost is worth not having to worry about my valve train wear.Check out their site at www.bradpennracing.com
With that added info on PPM who has the best pour in oil addtive??? this kind only comes in a 1oz bottle and claims "MotorHead ZBoost concentrate is the most zinc-rich additive you can buy (9.0% zinc) will raise the zinc and phosphorous levels by an additional 700 ppm (in a 5 quart oil change)" Anyone know how ZDDPLUS that comes in a 4oz bottle compares???

Complicated answer. Crane Super Lube has the highest tested concentration of zinc (Zn) and phosphate (P) at 130,000+ ppm. www.bobistheoilguy.com has lots of test results for oils and additives - they are called VOA (virgin oil analysis). ZDDP plus, CamShield, EOS, etc are good ones too. Short answer - you want to end up with at least 1200 ppm Zn and P but not more than 3000 ppm. Over .3% has been shown to increase wear. 1600 ppm is an old spec (SF, ca. 1989). 1200 ppm is not sufficient for cam break-in, but may be ok for lighter spring pressures, lower llift cams, etc. 1400 ppm should be the minimum if youy have high spring pressures, high-lift cams, etc. I would shoot for 1600+ ppm for new cam break-in. Also be careful about oils with high levels of detergents (like calcium, etc.) found in most diesel oils (HDEO). Some HDEO are ok. 2000 ppm and below is a good target. Too much detergent has been shown to reduce the anti-wear (AW) effect of Zn and P.
I don't know any one that has used it for break-in.I believe Royal Purple is a synthetic oil so check that out ,given that syn. oil is pron to leaking problems.As stated above i used Brad Penn Break-in given its characteristics.
