## Questions & Answers

**Q: Whats the differnce from this blue bottle and the high mileage one?**
A: The high mileage version contains stop leak and seems a bit thinner. I did not have good results with the high mileage version, but the standard on is great. The high mileage label also claims it cleans your engine, which seems like nonsense; it just made part of my engine oil turn into a gel. I recommend the standard version.

**Q: Can it be used with synthetic oil?**
A: I have a classic muscle car and use conventional oil and need the extra ZZDP. Not sure about synthetic oil, but my guess is not.

**Q: can you use this on modern cars? jeep 2006 burns oil - about 1 qt every 3 months**
A: This particular product has ZDDP and is not recommended for vehicles with catalytic converters. I would recommend the STP 17881 for synthetic motor oil.

**Q: Can I use this in my differential?**
A: Use only differential gear oils recommended by your owners manual.
