Thanks, Charles. I appreciate all the effort you and Jake have put forth and show it by purchasing your products. Let the sceptics be sceptics; like I really trust what the factory did to butcher these engines, when for minimal dollars, they could have produced them correctly.
Keep up the great work and we'll keep reading and upgrading. |

This issue, by the by, is not limited to Porsche M96 engines, and is more common than you might imagine. Back when I raced, it was not uncommon to see some really creative "north west passage" external coolant plumbing systems on some domestic engines to get more coolant flow to problem areas. Might not look very pretty, but if it kept you in the race, it was worth it................... |
Thank you Charles. Running higher oil temps to eliminate water and then offering long oil drain intervals as a marketing tool is the best explanation I have heard yet for Porsche running 180 T-Stats. Thanks to your research we know this was misguided. Running lower engine temps and changing oil more often has two benefits: The motor runs better and lasts longer. Makes sense to me.

Out of curiosity. Did you find that oil consumption increased with the lower t-stat?

No, we have not seen any increase in oil consumption with the LN stat; and (in fact) if anything would expect that we would see consumption decrease with lower operating temps, not an increase........................ |
Why I asked is because with lower temps you might see lower engine tolerances due to lack of expansion. (though at that temp difference it may mean nothing).

Oil consumption would decrease with the low temperature thermostat, if nothing at all, because the oil will be cooler, thus more viscous.
This is akin to the difference between running 0w40 m1 and 15w50mi in an aircooled 911 - a change as little as that has a huge affect on oil consumption, with the thicker oil using significantly less. My 964 would use 1 qt/700 mi with 0w40 and uses 1 qt/1500-2000 mi with 15w50 m1, for example. |
