As stated, turbo engines don't necessarily produce that much more peak cylinder/journal pressure/load. They do produce peak pressure for a much longer period. (Maximum Boost - Corky Bell.) Making a blown engine run well on thinner oil is just a matter of increasing journal/bearing area...

You might want to install an oil pressure gauge. That would give you some hope of spotting a clogging intake screen before the entire engine starves and dies.

Yea, 47.x MPG is gonna be SOOOOO awful! Please report the results of your gas guzzling debauchery.

The RC166's big brother can sound almost as good...

Good old UJM! A bit 'truckish' by today's standards, but fully capable of spirited riding. I'd use whatever dino 15w-40 is on sale every 1000 miles or so. May benefit from a front spring upgrade. 'Progressive' are better than stock, but straight rate-springs generally handle better. Looks...

Yes, a basic transmission cooler will work fine. Make sure the diameter is at least as large as the stock oil cooler. Most engines have a bypass built in to the oil system, usually just a large orifice that forces some of the oil through the cooler. If the cooler is restrictive, the oil is...

Won't hurt a thing. I'll bet that identical Corollas that wind up being exported to Australia are specified to run Xw-30 or thicker. The mileage impact will be some tiny fraction of one MPG that will be more than offset by the warmer weather of Spring.

3x 10w-30 and 1x 10-40 SM spec Valvoline Dino, purchased at a garage sale at 50 cents each!

FWIW, I found that my old Accord burns less oil when running 'German Castrol' 0W-30 than with M1 10-30MH. That said, my rate of consumption is about 1/6 of yours...

What about a block heater?

Unless your engine is a recovering sludger or is in the process of self-destructing, either of those filters will laugh at 10K. I chopped a Pure One at 10K and it was in as-new mechanical shape. (Granted, it was run on a sedately driven Accord.) Your candidate filters are, if anything, even more...

You might try something like M1 0w-40, GC 0W-30 (a thick 30w), various, somewhat rare, 0/5W-50 oils, or similar. Some of Redline's stuff also combines good cold flow and high HTHS. http://www.redlineoil.com/content/files/tech/Motor%20Oil%20Product%20Data.pdf The combination of 0W and Syn...

Mixed viscosity is pretty much proportional to the ratios of the oil multiplied by their viscosity. Assume 3 quarts of 3.0 and 1 qt of 5.4 gives.. ((Q1xV1) + (Q2xV2)) / Total quarts. (3x3) + (5.4x1) /4 (9 + 5.4) / 4 = 3.6 (Or close enough that it probably doesn't matter.)
