## Questions & Answers

**Q: I need one for my x5 in new jersey in the usa self it i’ll pay shipping**
A: You have Amazon in USA you should be able to get it through them. Bob

**Q: Do you just add to the engine oil?**
A: Yes after changing the engine oil and the filter just empty the contents of the seal conditioner in to the engine. Bit of advice if you car/van has high mileage I would use Forte engine flush before changing engine oil & filter.

**Q: How much do i need it for 3.0 bmw engine?**
A: I have a 3.0 Ltr engine coupled to an auto gearbox,  with a slight leak on the oil seal. I have used 2 x 125 ml tubes, as one tube is for engines up to 2 Ltrs. However, I have yet to monitor the results.

**Q: Do you deliver to the US**
A: As I don't work for the Company I can not answer the question. I am retired mechanic small garage owner that has used the Forte products for over 30 years and I have found after using other products on the market the Forte in my opinion is the only one that does what it said on the bottle. ( it works ) Bob the mechanic.
