[TR] 20-50 oil

[terryrs at comcast.net]

Regarding issues of sludge, how much of it has to do with using a top quality, micro-porosity oil filter like say WIX or maybe NAPA?

I've used Mobil 1 synthetic in my Tacoma with a WIX filter, changing both twice a year, and am at 264,000 miles with no oil burn or loss of oil (okay, half a quart) between changes.  Also in the TR3, which leaks oil with the synthetic, but last rebuild at 75,000 miles showed zero sludge.

Just a question.
