I recently saw Valvoline Synpower Synthetic oil on sale so I decided to look up it's VOA on PQA's web site . I noticed a high Sodium level which other than to throw off a Blackstone report may help with cleaning . I will also note that in terms of what I could see - Valvoline synthetic oil does not have an add pack that particularly jumps out at you versus M1 or PP...Your thoughts on sodium in a add pack as well as Valvoline Synpower in general ?
