[Healeys] ZDDP Plus

[Leonard Hartnett]

Following is a copy of the messge I sent to ZDDPPLUS and their response:

Hello Leonard,
The answer depends on your driving conditions and time between oil
changes.... With most daily drivers, approximately 50% of the ZDDP
molecule depletes after 1000 miles of driving. If you change your oil
every 3000 miles, and tend to drive in a sporty manner, I'd recommend
two bottles of ZddPlus per oil change. This will insure an adequate
level of ZDDP...
