This issue was not caused by the product, we have spoken to the particular customer. The exhaust pipe had caught fire near the Catalytic Converter. The fire was caused due to a very clogged catalytic converter. The owner did state that the car had a P0420 code and he added the product, P0420 code is a fuel related problem not oil or coolant. The customer actually used the HG-1 Head Seal not the OS-1 Oil Seal product. The review on amazon is false, the product did not have any factor in the vehicles issues.

Yes, you can use at or in-between oil changes.

@@BarsleaksUSA 2 questions: is it bad in any way, and what if you don’t drive the two hundred miles right away, do you have to?

@@StalinLovsMsmZioglowfagz no it is not bad in any way! The 250 miles we would typically like to see put on the vehicle over 3-4 days of driving if more that is ok. You just want to make sure that the product is circulating into the engine oil and getting to the seals and gaskets so we can solve that leak.

@@BarsleaksUSA I doubt she’ll be able to even go that far as she’s working all week. But if we ought to we can drive some at nite tonight. I think it’ll have been 3 days manana. Cheers
