Oil for older engines?

Just heard a castrol ad on the radio for oil for older engines...preventing
oil burnoff.

My '94 (157,000 miles) SL2 used just over a quart between oil changes (2,500
miles) when it was new. Now she's burning more. I'm using 10-30 oil.

Anyone have experience with oil for high-mileage cars? Should I use 10-40?
How about some of these additives that are on the market?

Thanks.

And thanks for all the help troubleshooting the whining noise in the engine.
Turned out it was the idler pully. Piece of cake to change out once I
removed the upper motor mount. I replaced the tensioner, too, while I was
at it. $51, and an extra 45 minutes. Well worth it, I think.

I've had good luck using an engine flush (add to you oil, run 5 minutes,
then change your oil and filter) then filling with Mobil 1. Cut my
consumption in half.

Straight 30 weight will work well. If it had been used from the get go, you
probably wouldn't be using oil now. Those thin assed multi vis oils are
worthless.

At normal engine operating temperatures 5W30, 10W30, and
straight 30 weight have almost identical viscosities. When
cold, the 5W30 and 10W30 flow better than the straight 30
weight. There are still applications for straight weight
oil, but modern engines, as used by most people, aren't one
of them.

That might be true if you lived somewhere where it was constantly hot!



....Cold starts, biggest wear factor on an engine. Why make it worse...

Has worked fine here for 35 years. temps from minus 20 to 100+. 30 weight
all year around in my personal vehicles AND the fleet of 35 I'm in charge
of. Diesels, gassers, 4 cylinder up to DT466

And I have been using multi-viscosity oil for 35
years...including five different farm tractors with diesels.
I've never had any sort of engine failure related to the
oil.

Straight 30-weight is only thicker in cold temperatures, when you DON'T want
it to be. There is no reason to use straight-weight oil in a modern engine.
