thanks so much that does sound easy!You can submit payment (credit card) on the form in the bottle when you return it or just enter the payment on their website with your account. Easy peasy. They'll send you several sample kits.
It there any particular reason why you feel it should be higher if they put a full quart extra? I don’t know where exactly the dip stick enters the engine or whether it’s at an angle to provide more resolution so I’d love to know if there’s something you know lolThat is exactly the same as mine, I would think if it was an entire quart over it would be higher up.
