Thanks for the added info. I wonder if there is some formula for oil consumption which might be a function of displacement and average rpm or something like that?
 
For me it's been all over the map. I've had engines big and small, low revving and high revving that have and have not used oil. The worst was a '92 Saturn SL2 that burned about a 1qt every 500 miles after 60k miles and Saturn said it was normal.
 
My first car was a '75 Buick Regal with a 350, my grandpa bought it new and gave it to me in '87. It used a qt every 1,000 miles since it was new. It still lasted well over 130k. Trans was heading south when I got rid of it.
 
I had a '98 Ford SVT Contour which had a DOHC 2.5L 195hp v6 that would easily rev to it's 7200rpm fuel cut off. It never used a drop of oil over the 75k miles I put on it and I beat that car using it in many SCCA Solo II competitions and such.
 
The '03 305 v8 in our boat has never used any oil either and you'll be hard pressed to find a harsher environment for a car engine (basically a car engine with a few marine spec parts). It's spent many hours running 1/2 to full throttle at 3k - 5k rpm.
 
I had a '95 Neon with the DOHC 150hp 2.0L 4cylinder that also would rev to 7k rpm and it would occasionally use a qt per oil change interval, never a big deal. I'd have to add a qt occasionally to my 5.3 powered Suburban, primarily if I had been towing the camper or boat a lot in hot weather. The 5.4 in my Expedition has yet to use any oil at 51k miles.
 
I think the owners manual in every vehicle I've owned has stated some oil consumption is considered normal. It probably comes down to variation in the manufacturing process. Some will some won't I guess unless it's a Northstar and then it's considered a normal side effect of it's exotic machining process or whatever...LOL

I don't understand why it's a big deal to add a quart of oil once in awhile.
 
I've had a couple of Mazda RX-7's and they need to burn some oil. I know that I had to watch the oil level and add a quart about once every 1000 miles.
 
If I had a Northstar I would do the same thing. Not a big deal.
 
With our Hondas, I rarely check the oil level between changes and I guess I should in case they decide to start using a bit of oil.

Many years/decades ago, that was the norm, the expectation. In my own experience with GM vehicles with V8's in the 70's, 80's, 90's, adding oil was not questioned.
 
Starting in 1984 with first Honda, I was pleasantly surprised that it did not need any oil additions to crankcase between changes. That has been my experience with many Hondas and Acuras (and Nissan) since then.
 
The Japanese auto builders had refined the engineering of their engines to have attributes of good power, reliability and no (or extremely low) oil consumption between changes.I recall the sales brochure of my 97 Maxima extolling the advanced engineering features of their engine including a term, if I recall, micro fine finishing on all interior engine and component touching surfaces.
 
Apparently, GM was incapable of engineering a Northstar engine without having to use a quart of oil every 1k-1.5k from what I hear.
 
Imagine if norm was "burning" one quart of oil every 1k miles for every vehicle manufactured today. What a waste of petroleum resource, not to mention added pollution.

but people have better things to do with their time than baby their cars.
 
They do? I can't think of anything better!

Also, the Northstar holds more oil: 8 qts vs. the usual 5.

Wow. If this is Harley Earl's personal 'Vette, he'd have been 71 years-old when it was new! Go, Grandpa, go!

Jim Mateja, Chicago Tribune writer/tester for last 30 years, listed his 10 most memorable GM cars in yesterday’s newspaper.
 
1959 Cadillac – sports largest tail fins ever
2002 Cadillac CTS – saved the division with its leading edge design
1954 Chevrolet Corvette – true American sports car
1957 Chevrolet Bel Air – featured tail fins, one of most popular collector cars
1960 Chevrolet Corvair – immortalized Ralph Nader’s Unsafe at Any Speed
1967 Chevrolet Camaro/Pontiac Firebird – double barrel competition for Ford Mustang
1964 Pontiac GTO – launched muscle car era in US
1984 Pontiac Fiero – last minute GM decision made it a 4-cyl econocar
2001 Pontiac Aztek – defined butt ugly
1996 EV1 – started life as Impact, the worse car name ever
 
No Buick, Oldsmobile, Saturn, Hummer, GMC, Saab on top 10 list.
 
Pictures of the cars were shown by decades: 50's, 60's, 80's, 90's, 00's. Nothing memorable from 70's by him.

Yeah, that's HIS opinion. Notice there's nothing before the 1950s either and a few glaring omissions. Why mention the 1954 Corvette when the 1953 model was the first Corvette? The CTS debuted as a 2003 model, not a 2002. I wouldn't credit it as having saved the Cadillac division as much as the Escalade. The EV1 is memorable? By whom? Why is the EV1 a bad name? I'd say "Edsel" was a much worse name. Even the Ford family didn't really like it. Notice, he only mention three as to bash GM. I'm surprised the knucklehead didn't mention the Vega if that was his intention.

The most awesome Buicks on your list, in my opinion, considering their period were the first three ('36 Century [arguably the first muscle car with big engine in a mid size body], '41 Limited, '41 Roadmaster), and the '63 Riviera. The were drop dead gorgeous cars.
 
I think you may have meant the '49 Olds 88, which was the first model year for the all-new Rocket V8. It was introduced in the fall of '48.
 
The first generation Toronado was a break-through design, even though several European cars and Cord featured front wheel drive much earlier. I believe the Toro was the first powerful FWD V8 with automatic transmission, with available seating for six.
