my friends 97 civic has about 250k miles and its consuming maybe 1 quart every 2k miles. He lives in San Francisco, so temps are usually from 50-70f. I was thinking Valvoline Maxlife 10w30.

I run #2 HHO in our Carlin 99FRD. Oh, You mean a car? How can you register a oil burning car in Cali?! - Why, then do I bother purchasing a ULEV engine in a new car?!

To answer your Q:
I would go for Shell Rotella 10w30 triple protection or Pennzoil High Mileage w/ a hefty vis for a SAE30 (last I looked) QS redbottle 10w30 is also worth a look for a 12cSt SAE 30 with a 12 NOACK.

The ML 10W30 is a good choice. Could also try 10W40 or Quaker State High Mileage. I had poor results with Pennzoil High Mileage in my truck previously compared to ML.
 
10w30 Max should work well. If it doesn't seem to help then as already mentioned buy a cheap oil like supertech 10w30 or 10w40.

Kinda depends on the habits of the individual engine. most engines will burn less oil if you go to thicker grades, but some engines do just the opposite. My working theory is that if the oil control rings are weak, sometimes they "skate" over thick oil instead of scraping it off the way they should. Those engines might burn less thin oil since the rings can scrape it down better.

But frankly a quart every 2-3k miles isn't severe at all. Yes, its a lot for a little 4-banger that normally can go a whole oil change without make-up oil, but its still not what you'd call bad. The other thread where a car needs a quart or two every other fill-up has bad oil consumption.
 
You can give maxlife a shot it helped consumption for some of us. You can try experimenting with different brands and grades too.
 
Just for the heck of it, you might try something like Rotella 15w40 - it worked in my '87 Camry that used oil. Didb't stop the oil consumption, but it did cut it in half.

im glad someone finally mentioned this. especially with that many miles, that oil loss is not that bad

Exactly! At 250k and 13 years there is nothing out of ordinary going on with the engine. But if OP feels like experimenting with different types of oils and viscosities, I say go for it, this car is perfect for it, just make sure to post your findings

It depeneds on what is causing the oil burning, Shell did a study and IIRC if it is the rings, upper ring in particular a 20 grade actually was better than a 40 grade for lowering consumption. Goes against what most were told, but it spells it out in the article. If it is bad stem seals and valve guides a HM 10W30 is good, Schaffers #132 added to the oil lowers consumption as well in some instances.

Now the good news, an engine with 250,000 miles on it using a qt of oil every 2000 miles is doing just fine. Car makers consider oil burning for warranty claims as a qt/1000 miles normal. Go figure

Do you know where to get this info? Go to shell for this product and click on the PDS link.

I am at work and I dont have my Oil library loaded here. 10w30 HDEO should be more stable than the risky, dirty, unstable 10-40, all else being equal. 15w40 is too thick for this app IMO.

My Nissan QR25DE used more than that from day one and Nissan said it was 'normal'.
