I am going to be changing my oil tomorrow that has been in my car for 5,500 miles. I use G.C Syntec 0W-30 and used six quarts when I changed it last and I have only had to put a little less than 1/4 quart in to keep it completely full on the dipstick, so it barely uses any. Unlike when I was using M1 5W-30. Anyway where do you guys send your oil out to? How much do you have to send also?

 

Blackstone Lab, just look the up on the net to get their website. Once there just fill out a form and they will mail you a sample kit to put your oil in with instuctions and all.
