THANK YOU! I saved $2,500.00 by using your product.  One of my lifters was stuck on my BMW X5 and the mechanic told me that it was going to cost 2500.00 to fix it.  I went to my local pep boys and spoke to a great salesmen.  He suggested I try the Synthetic oil stablilizer, put it in my car and 1/2 hr later my ticking noise was gone!!! Thank you so much for a great product!!
