2014What year is your Durango?
Their 5w-40 is really stout. More than any 5-40 Walmart carries.Here is the PDS for our HDMO motor oils. We have an extensive range of viscosities available. They are all available in quart cases, gallon cases (4X1), 5 gallon pails, 55 gallon drums and 320 gallon totes

I think that's what we will do, when the UOA shows the oil is condemned or close to being condemned, then we'll change.Why automatically stop at 20,000 mi?
Sample every 5,000 mi and change the filter as required (20,000 mi?). Change the oil when the analysis says it's time.

A TBN of 12.3 with 5k miles on it? That's either incredible, or a testing error.
It's accurate. It's part of HPL's specialization, make oils that have great performance and are safe for extended drains.

Lot of you are impressed with HPL 5W-20 high TBN and such oil can be considered safe for extended drains since it has a high reserve of alkalinity to neutralize harmful acids. HPL 5W-20 has on average about 30% higher TBN compare to at least half a dozen 5W-20 oils I looked at.
The oils I looked at which had higher TBN had always higher mg/kg of detergents (Ca & Mg). Since ash is the result of non-combustible residue of oil detergents like Ca and Mg, wouldn't oil with too high TBN also contribute to higher deposits build up on valves and pistons?
Thanks.Not if the oil isn't evaporating much. Higher SA%, but lower volatility.
Thanks.
Didn't know that oil volatility had effect on ash. I thought that oil volatility had only effect on viscosity. Less volatile oil the longer it retains its initial viscosity.
