I just changed oil (for the first time) and considered changing to

Mobil 1 until

I saw the price ($4.50/qt vs. $0.99 for Discount Autopart's).

Is it really worth it? What's the advantage.

One thing I should mention. The oil I drained (after maybe 40 hours

on the

engine) was dark (black). I didn't think there'd be any blow-by in a

rotary?

I would bite the economic bullet and use Mobil 1. Way better than

regular oil

in resisting break down at high temp. You can get get it in Walmart by

the

case for less than $4.50/qt I think.

Thanks, I'll check that out.

Interesting on that dark black. How is your compression?
Was that the cheap  $0.99 oil? Did you lap those end housings?

I haven't checked compression the last couple of years and don't remember

the numbers

before that. Yes, that was the cheap oil. No, I didn't lap the end

housings.

BTW, I had to run the starter for more than 2 minutes before I got oil

pressure

showing! I guess next time I should try filling the oil filter before

mounting it.

Another point. After my no-oil pressure bearing failure, I decided to add

ProLong. Is

there now a better additive out there? I really like the idea of being

able to limp

home without the bearings sizing after oil loss.

What caused the loss of oil pressure?

I have no experience of rotaries other than stripping a well used 1988 turbo
model. The oil had been drained before I bought it bu what struck me was how
clean the remaining oil was and everything else in the engine, there was no
sign of gunge I have always found in a piston engine
