## Questions & Answers

**Q: Can use zerex g-05 in all bmws, all mini coopers, and all mercedes benz? how come the colour is different? (my 2012 mini cooper countryman)**
A: The Zerex G-05 Antifreeze/Coolant, Ready to Use - 1gal (ZXG05RU1) can be used in all 1997-2011 BMW, MINI, and Mercedes Benz. However, in 2012 the coolant specification was changed and we suggest the use of the Zerex G-48, which unfortunately is not available through Amazon at this time.

**Q: Can i use this in my 2001 nissan xterra**
A: Unfortunately, Zerex would not recommend this product for your 2001 Nissan Xterra application.  The Zerex product that would be recommended for all 2000 and newer year Nissan vehicles (including the 2001 Xterra) is the Zerex Asian Vehicle Antifreeze/Coolant, Ready to Use - 1gal (675130).

**Q: Can i mix coolants in '01 saab? i have slight leak so i occassionally add all make all models green coolant? can i now switch to this brand?**
A: The Zerex G-05 Antifreeze/Coolant, Ready to Use - 1gal (ZXG05RU1) is a universal top off, but if you are needing to add more than a quart of coolant, we recommend using the Zerex DEX-COOL Antifreeze/Coolant, Concentrated - 1gal (ZXEL1) for any 1997 and newer SAAB.

**Q: Is this vw Audi g12 equivalent or better?**
A: Even better same the green for your tires .
