Mobil 1 oil weight

[Taka Mizutani]

Same experience here- Mobil 1 15W50 (before they went to the crap Type III
that they're using now) never burned any oil, no lifter clatter, good oil
pressure and oil temps. Even subjected to summertime track abuse, the oil
didn't crap out on me.

I won't use the light stuff in the I-5 cars- I tried Castrol 5W50 in the
200, LOUD lifter clatter, oil consumption, etc.

Mobil 1 10W30 in the winter months was okay, but I used oil, maybe 1/2 qt.
every 5k oil change.

I'm currently running Pennzoil Platinum 10W30 (the old Group V stuff) or
German Castrol Syntec 10W30 or my last existing bit of the old Mobil 1
10W30.

I've put Quaker State Q Power full synth in the Miata, because it's normally
aspirated, not high strung and I don't really care- engines are dirt cheap
for a Miata. Still run full synthetic and do 3-5k oil changes even in the
engine that I don't care about.
