I'm curious of how the relative capability (drain length) of oils that meet various common specs. For instance how would a basic SP GF-6 compare to a basic Dexos 1 Gen 2 Oil.
The lowest cost brand name that meets those specs at the local Walmart is Havoline.
Havoline Synthetic Blend 5W-30 SP GF-6
$16.97 per 6 qt of 5W-30.
Havoline Pro DS Lifelong Synthetic D1.2
$19.65 per 6 qt of 5W-30.
How much longer drain (if any) would you expect the D1.2 oil to be capable of?
I'm asking an opinion. I know the proper way is with analysis of the vehicle, driving habits and lubricants involved.
Disclaimer: This isn't a question about whether you drain your oils at 1,000 mi or 40,000 mi. If your answer is zero that's fine.
