## Questions & Answers

**Q: What is the rated mileage for this?**
A: I don't think oil is rated, the engine it goes in is but synthetic oil will last longer than regular oil.

**Q: is this only one 1 quart bottle or six 1 quart bottles?**
A: Six (6) - 1 quart bottles.

**Q: Does this product includes filter?**
A: No filter with the product.

**Q: Is it ok to top off regular oil with some of this oil as needed for a slow oil leak?**
A: I have a beater that i use for grocery shopping and Dr appts. It burns oil possibly worn valve guide seals. A friend told me to use synthetic or high mileage and it should help a little. Since i burn about a quart a month ive used everything from this to little known brands. My car still runs fine, passes inspection, no check engine. Oh by the way using a synthetic or a high mileage did cut down on oil consumption.
