Can you guy's who keep saying this please post in writing where you saw this?
I can't believe the additives would be that expensive to out weigh the cost of running a complete new run of different oil.
I'm thinking whoever is saying this heard it from their 2nd cousin's best friend who works for Ashland.
Or just looking at the VOAs and UOA where napa has aroud 1700ppm of Calcium and synpower has over 2000ppm Calcium, Napa around 250 sodium, synpower 400ppm sodium.
This is quoted in this thread.
I just got this from Ashland. Sounds like the NAPA synth is a really good oil.
How similar is NAPA synthetic to Synpower? Also,how would the NAPA synthetic 15W50 compare to Mobil 1 15W50? Reason I ask,is that the NAPA synth goes on sale at a really good price and the M1 15W50 can be hard to find and/or expensive. Do you have a material data sheet you can email me for the NAPA synth 15W50 (that lists the viscosity,zddp,moly,flash point,pour point,etc)? Thanks.

Good afternoon,
Thank you for contacting Valvoline Product Support with your motor oil question.
The NAPA Synthetic Motor Oil and the Valvoline SynPower Motor Oil are both derived from the same base stocks, however, the additive and detergency package may vary between products.
The NAPA Full Synthetic 15w-50 does meet and exceed all the API service ratings listed on the container. Valvoline uses a superior additive package on top of the use of the highest quality base stocks available.
To locate MSDS sheets for our products we request that you visit
