Run low oil volume, increase oil temperature?

Some years ago, a recognized industry expert, Terry Dyson, posted regularly on BITOG.
There was a long running thread involving this expert and a member who had some sort of very high-po Audi that had terrible fuel dilution problems.
A number of used oil analysis were done, which showed that the fuel dilution was having a significant impact on engine life.
The ultimate soloution was for the owner to use an ester basestock oil in his engine, from RLI.
I wonder whether fuel dilution problems might be reduced with your engine if you tried an ester based oil?
G-oil is such a beast, Dexos 1 or not, and it is certainly fairly inexpensive, if it works, while RLI oils are more costly.
I'm just throwing this out there in case you would want to consider leaving the Dexos 1 spec behind and searching for an oil that might really work in your situation.

+1, but at present it appears to be the most economically prudent thing to do.

Should the dilution began to manifest itself as overly problematic I can't rule out giving anything a try. During the warranty period I would first switch to a dexos2 oil in order to have some shred of argument that I am staying within specs (at least European ones) so as to arguably not invalidate the warranty. (Though I am not so sure an ester-based oil would preclude dilution as opposed to better deal with it.)

You could leave it a quart low and add 5W-50 at 2K miles or to off set the fuel dilution...

I was the one who recommended that a guy should try using 1/2 qt less in the sump. He was interested in a heat exchanger - [a big royal pain] and I offered an option.
1/2 qt, or even 1 qt, is not low. It is over the minimum mark on most cars. Oil will heat up faster - less capacity.
BTW, we have to consider not just the oil pickup, but there is splash lubrication.

The opposite approach -This is why large sump oil and transmission pans are use in some racing. Simply so the oil heats up slower and runs cooler.

An engine does not have to have 212 F oil to eliminate water in the oil. Similar for fuel. It does so with normal warm/hot heat and the PCV system.
