Synthetic Oil with Additive Package = Better Protection
This is a curve from an IntelliStick customer with a 2007 Mini Cooper S, super charged. It is driven in stop and go conditions. This customer uses Royal Purple 5W 30 and bumps it with a BG MOA additive package. BG MOA is a high-end additive package that you can’t purchase at just any auto parts store. For more info on BG MOA, check out their web site at: http://www.bgprod.com/products/engineoil.html
In contrast to the customer using a traditional oil without an additive package, this customer’s additive protection lasts nearly twice as long - 800 miles vs. 450 miles. What we don’t know is what the curve would look like without the BG MOA.
While the additives are depleted after 800 miles, oxidation will not become a critical issue for at least another 4,000 miles. This customer changes his oil every 5,000 miles. It’s possible he could go longer between oil changes.
