Between my cars and the cars of my customers, approximately 15,000 gallons of this oil (using the same storage and filtration methods) has been ran through a wide variety of single and dual tank converted cars and trucks over the last decade without any problems whatsoever.
Some advance notice is preferred for amounts exceeding 40 gallons of oil at a time.
