     It seems that Rotella T is being replaced by Rotella T1, which no longer contains 1400 ppm of ZDDP additive.

 

     Vech revealed his findings from his inquiry with Schell Oil.  The new Rotella T1 has less ZDDP additive than regular Rotella T. Vech says Shell still handles to ‘T’ version, only it harder to get.

 

      There are alternatives, but first, let us discuss why ZDDP is important as an additive in the oil we stuff into our engines. Originally it was added to oil to aid in corrosion protection. Here’s what Vertechhal of Sheridan, WY has to say in one of their tech briefs:

 “...The same corrosion protection afforded to the block by ZDDP is afforded to cams and lifters. The special consideration for these components is their unique wear mechanism as they rotate in a sliding boundary lubrication mode. This is the third and most unexpected benefit of ZDDP. As discussed at length I previous Tech briefs, ZDDP has a unique mechanism of forming a glassy anti-wear coating between rubbing parts. Oils began incorporating ZDDP in the late 1930’s, and when the horsepower race began in the 1950’s, the demands on anti-wear characteristics of oil became severe. It was then noticed that the formulations containing ZDDP afforded the greatest anti-wear protection to the cams and lifters. This gave additional impetus to oil formulators to increase the levels of ZDDP in their heavy duty formulations. To date, there has been no anti-wear agent which has equaled the protection afforded to flat-lifter cams by ZDDP.”

This message came from the internet: 

     I called Castrol Consumer North America 1-800-462-0835 regarding ZDDP in Castrol Grand Prix 20W-50 Motorcycle Oil. The minimum ZDDP in this product is 1200 ppm and it could be as high as 1500 ppm. They said the levels in their automotive products had been lowered but at this time they were not intending to lower the ZDDP in their motorcycle oil.

 

     This wasn't their first call regarding this topic as the rep had the answers as fast as I asked the questions.

 

     The ZDDPlus web site says heavy duty oils used to have a level between 1200 -1600, today the levels are in the 600 range. ZDDPlus bases their dilution calculations on oil having the reduced amount of ZDDP. I will add 20 mls or less than 1 oz of ZDDPlus at my next oil change.

 The stuff is about $9.00 a bottle which will treat 4-5 quarts of oil, in other words it means one bottle would be good for two oil changes. Here’s another:

      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. Simply add ZDDP-Plus to every 4-5 quart oil change and your motor will be protected from metal to metal contact. Add one 4 ounce bottle to a 4-5 quart oil change modifier to eliminate any metal-to-metal contact.
