## Questions & Answers

**Q: Can I use it in a 2000**
A: Honda s2000?  2000 model year Ferrari? 2000 individual mini cooper's? Perhaps the answer isn't in the answer. Perhaps the answer is in the question. As in, why would you touch your vehicle if you can't ask an appropriate question?

**Q: will this work for a 98 jeep cherokee auto 4wd**
A: Here is a link to the list of approved vehicles from Castrol!!!

**Q: does this fluid replaces ATF-Z1?**
A: ATF-Z1 is Dex3 with a friction modifier. This will cover that spec. As the trans ages & wears you may be better served by using a higher viscosity fluid such as AMSOIL ATF. If you are doing a drain & refill, the ffirst one is about 44% new fluid replacement. The 3rd. one will take you to 85%. Think diloution rate vs. volume.

**Q: Can this work w/ toyota camry 1999 uses dexron iii? also, can i mix other brand dexron iii (not for hi mileage) w/ this castrol atf for high mileage?**
A: Yes and yes.  However, in my experience, Dexron VI (even in an old worn transmission) will dramatically improve shift quality even in transmissions rated for Dexron III or Toyota Type IV (which is rebranded Dexron IV).
