I'm planning on using one or the other for my next oil change, and I'm open to opinions on which one? 132 is their moly ep additive, which I would add to regular engine oil. 703 is their supreme 7000 10W-30. I figure I could order 3-4 bottles online of the 132 and that would be cheaper than a case of 7000 from my local rep. I would not be adding the additive to the 7000. Thanks.
