I had a 1990 Probe GT which I bought new and kept for 13 years/115,000
miles. It still ran like new and used no oil between changes. After it was
broken in, I used nothing but Mobil 1 synthetic oil, both 10W-30 and
later,
when Ford changed their recommendation, 5W-30.
As long as your Probe is not burning oil, a good 5W-30 or 10W-30 synthetic
like Mobil 1 would be the best for the turbo bearings. If you are having
to
add a quart or more between oil changes, then you might want to use 20W-50
(and forget synthetic, because your engine is already too worn to benefit
from the extra expense).
