In looking through some industry articles this morning, I see that Joe Gibbs is marketing a new oil. It is specificly designed to address the ZDDP issues. Go to www.JoeGibbsDriven.com for more information. --Further reading into the FGF wisdom points out this had been mentioned. I usually wake up later in the day.
Greg, I'll have to spend some time looking through that JoeGibbs site on the issue. I did note that there is not a straight 30W, which I must use on my 400HO. Second, I would want to be sure that the oil is appropriate for daily use application. Note the information from the ZDDPlus website:
Why Can't We Use Racing Oils? There are some racing oils which maintain a level of ZDDP. Racing oils are optimized for short term severe duty, in contrast to an oil that has been designed for day in, day out street operation. The additive package in a racing oil does not have the same detergent characteristics which are designed into extended service oils. As a result, racing oils may not have the capability of neutralizing acids and keeping contaminants in suspension. Also, the breadth of choice of viscosity, so important to correct street engine operation over a broad temperature range, is not available in racing oils.
By using ZDDPlus™ in addition to a modern high-quality oil of the proper viscosity for your gasoline engine, the correct EP lubrication level is established, and the oil characteristics remain optimized for your engine.r engine.
It does seem odd that staight 30wt isn't available. It took me a long time to get away from the old rule, 30wt summer & 20wt winter, but after making the decision to use the high pressure pump in the 428, I felt a need to try 10w30. It seldom gets to 1,000 miles on a change of oil, which may be a little over cautious, but with the amount of fuel I push through, I do what I can to prevent diluting the oil.
Holy cow! $65 oil change. (oil & filter)
